在动画设计中，通常会设置内层模型与外层模型之间的半透明效果，例如，皮肤模型和衣服模型的半透明显示。相应的，半透明显示主要是依赖内层物体所反射的光经过一定距离后穿透外层物体并入射到人眼后所显示的效果。其中，各模型是由一个个点构成的，当内层物体上的点与外层物体上与其相对应的点的距离越远，半透明效果比较弱，反之半透明效果就相对比较强。In animation design, the translucent effect between the inner model and the outer model is usually set, for example, the translucent display of the skin model and the clothes model. Correspondingly, the translucent display mainly depends on the effect displayed after the light reflected by the inner layer object penetrates the outer layer object after a certain distance and is incident on the human eye. Among them, each model is composed of points one by one. When the distance between the point on the inner layer object and the corresponding point on the outer layer object is farther, the translucent effect is weaker, and vice versa, the translucent effect is relatively strong.
相关技术中，确定半透明效果，主要是设定外层模型的透明度显示值，该透明度显示值通常是固定不变的，外层模型上的所有点依据设定的透明度显示值来实现透明显示，此种方式产生的透明显示效果与实际情况存在一定的偏差，透明显示效果不佳，用户体验较差。In the related art, determining the translucent effect is mainly to set the transparency display value of the outer layer model. The transparency display value is usually fixed, and all points on the outer layer model realize the transparent display according to the set transparency display value. , the transparent display effect produced by this method has a certain deviation from the actual situation, the transparent display effect is not good, and the user experience is poor.

The target detection point may be a preset detection point on the first sub-model; it may also be that the preset point on the first sub-model is divided into a plurality of blocks, and the center point of each block may be used as the target detection point; or It can be a detection point set by the developer according to actual needs; of course, it can also be that the first sub-model is composed of multiple points, and each point can be used as a target detection point. The photographing device is a device for observing and photographing the first sub-model, and the relative photographing angle is the relative angle between the photographing device and each target detection point on the first sub-model. The relative shooting angle information is determined according to the position information between the shooting device and each target detection point.
例如，拍摄装置与每个目标检测点所对应的目标拍摄角度存在差异，根据拍摄装置与第一子模型上每个目标检测点的相对位置关系，可以确定拍摄装置与每个目标检测点的相对角度信息，并可以将该角度信息作为相对拍摄角度信息。For example, there is a difference in the target shooting angle corresponding to the shooting device and each target detection point. According to the relative positional relationship between the shooting device and each target detection point on the first submodel, the relative position of the shooting device and each target detection point can be determined. angle information, and the angle information can be used as relative shooting angle information.
S120、对每个目标检测点，确定与当前目标检测点相对应的目标重建函数，并将与当前目标检测点对应的相对拍摄角度信息输入至目标重建函数中，得到目标检测点在当前拍摄角度信息下第一子模型与第二子模型之间的距离信息。S120. For each target detection point, determine a target reconstruction function corresponding to the current target detection point, and input the relative shooting angle information corresponding to the current target detection point into the target reconstruction function to obtain the target detection point at the current shooting angle The distance information between the first sub-model and the second sub-model under the information.
其中，第一子模型为包裹第二子模型局部的子模型；重建函数是基于目标 检测点在球谐函数中各基函数上的投影系数值构建出来的。每个目标检测点存在一个与其相对应的目标重建函数。Among them, the first sub-model is a sub-model that wraps the part of the second sub-model; the reconstruction function is constructed based on the projection coefficient value of the target detection point on each basis function in the spherical harmonic function. Each object detection point has a corresponding object reconstruction function.
为了清楚的介绍本实施例技术方案，可以以重建其中一个目标检测点的重建函数为例来介绍。In order to clearly introduce the technical solution of this embodiment, the reconstruction function of reconstructing one of the target detection points may be used as an example for introduction.
其中，目标检测点的重建函数是根据球谐函数对当前目标检测点的投影系数进行处理后，得到当前目标检测点向空间中每个方向发射物理射线时，物理射线与第二子模型碰撞时所对应的距离值构建出的函数。重建函数可以用于对输入的相对拍摄角度进行处理，以确定在该相对拍摄角度下目标检测点所对应的第一子模型与第二子模型之间的距离信息。Among them, the reconstruction function of the target detection point is to process the projection coefficient of the current target detection point according to the spherical harmonic function, so as to obtain when the current target detection point emits physical rays in each direction in space, when the physical rays collide with the second sub-model The function constructed from the corresponding distance value. The reconstruction function can be used to process the input relative shooting angle to determine the distance information between the first sub-model and the second sub-model corresponding to the target detection point under the relative shooting angle.
例如，基于预先设置的球谐函数中的每个基函数对当前目标检测点所对应的投影系数值进行处理，可以得到当前目标检测点向空间中每个方向发射物理射线时，物理射线与第二子模型碰撞时的碰撞点与当前目标检测点的距离信息。根据当前目标检测点所对应的空间中每个方向的距离信息，构建当前目标检测点所对应的重建函数。For example, by processing the projection coefficient value corresponding to the current target detection point based on each basis function in the preset spherical harmonic functions, it can be obtained that when the current target detection point emits physical rays in each direction in space, the physical ray and the first The distance information between the collision point and the current target detection point when the two sub-models collide. According to the distance information of each direction in the space corresponding to the current target detection point, a reconstruction function corresponding to the current target detection point is constructed.
在确定当前目标检测点与目标拍摄装置之间的目标拍摄角度后，可以将目标拍摄角度输入至与当前目标检测点所对应的重建函数中，重建函数可以对目标拍摄角度进行处理，输出目标拍摄角度下当前目标检测点与目标拍摄装置所属直线与第二子模型碰撞时，碰撞点与当前目标检测点之间的距离信息。After determining the target shooting angle between the current target detection point and the target shooting device, the target shooting angle can be input into the reconstruction function corresponding to the current target detection point. The reconstruction function can process the target shooting angle and output the target shooting angle. The distance information between the collision point and the current target detection point when the current target detection point and the line belonging to the target photographing device collide with the second sub-model under the angle.
示例性的，在确定某个目标检测点A的重建函数后，并在确定该目标检测点与拍摄装置之间的相对拍摄角度为45°时，可以将相对拍摄角度输入至目标检测点A的重建函数值，可以得到目标检测点A在该角度下目标检测点A所对应的第一子模型和第二子模型之前的距离信息，如，得到的距离信息为5nm。Exemplarily, after the reconstruction function of a certain target detection point A is determined, and when it is determined that the relative shooting angle between the target detection point and the shooting device is 45°, the relative shooting angle can be input to the target detection point A. Reconstructing the function value, the distance information before the first sub-model and the second sub-model corresponding to the target detection point A at this angle can be obtained. For example, the obtained distance information is 5 nm.
需要说明的是，每个目标检测点与拍摄装置之间的相对拍摄角度存在一定的差异，可以确定每个目标检测点与拍摄装置之间的相对拍摄角度，并将确定的角度作为与每个目标检测点的相对拍摄角度。It should be noted that there is a certain difference in the relative shooting angle between each target detection point and the shooting device, and the relative shooting angle between each target detection point and the shooting device can be determined, and the determined angle is used as the The relative shooting angle of the target detection point.
S130、当检测到第一子模型为半透明显示时，根据各目标检测点所对应的距离信息，确定与各目标检测点所对应的待碰撞点的透明度信息。S130. When it is detected that the first sub-model is translucent display, according to the distance information corresponding to each target detection point, determine the transparency information of the to-be-collision point corresponding to each target detection point.
其中，半透明显示可以理解为第一子模型所采用的材料为半透明材料。与每个目标检测点所对应的距离信息可以相同也可以不同。每个目标检测点所对应的距离信息指的是拍摄装置与目标检测点所属的直线与第二子模型碰撞时，目标检测点与待碰撞点之间的距离。透明度信息是用于表示模型显示时的透明程度，可以使用百分比来表示，例如：透明度为80％等。The translucent display can be understood as the material used in the first sub-model is a translucent material. The distance information corresponding to each target detection point may be the same or different. The distance information corresponding to each target detection point refers to the distance between the target detection point and the point to be collided when the line to which the photographing device and the target detection point belong collide with the second sub-model. Transparency information is used to indicate the degree of transparency when the model is displayed, which can be expressed as a percentage, for example: the transparency is 80% and so on.
需要说明的是，确定不同目标检测点的透明度参数是采用相同的方式，为 了清楚的介绍本实施例技术方案，以确定其中一个目标检测点的透明度参数为例来介绍。It should be noted that the same method is used to determine the transparency parameters of different target detection points. In order to clearly introduce the technical solution of this embodiment, the transparency parameters of one of the target detection points are determined as an example to introduce.
例如，根据与当前目标检测点所对应的第一子模型和第二子模型之间的距离信息，确定当前目标检测点的透明度参数可以是：根据距离信息在预先存储的距离信息与透明度参数之间的对应关系中确定透明度参数，也可以是根据预先设置的透明度参数计算模型来计算，将距离信息输入至透明度参数计算模型中，经过计算可以获取与该距离信息对应的透明度参数。For example, according to the distance information between the first sub-model and the second sub-model corresponding to the current target detection point, determining the transparency parameter of the current target detection point may be: according to the distance information, between the pre-stored distance information and the transparency parameter The transparency parameter is determined in the corresponding relationship between the two, or it can be calculated according to a preset transparency parameter calculation model, and the distance information is input into the transparency parameter calculation model, and the transparency parameter corresponding to the distance information can be obtained through calculation.
示例性的，将距离信息记为dist，若0nm＜dist≤5nm，透明度参数为90％，5nm＜dist≤10nm，透明度参数为80％，当dist＝7.5nm时，对应的透明度参数为80％。Exemplarily, the distance information is recorded as dist, if 0nm<dist≤5nm, the transparency parameter is 90%, 5nm<dist≤10nm, the transparency parameter is 80%, when dist=7.5nm, the corresponding transparency parameter is 80% .
当然，也可以采用相应的计算方式来确定透明度参数，其中，透明度计算公式为a i＝f(l i)，其中，a i表示第i个目标检测点，l i表示第i个目标检测点所对应的第一子模型和第二子模型之间的距离信息，f为具有单调性，且是单调递减的函数。 Of course, a corresponding calculation method can also be used to determine the transparency parameter, wherein the transparency calculation formula is a i =f(li i ), where a i represents the ith target detection point, and li represents the ith target detection point For the corresponding distance information between the first sub-model and the second sub-model, f is a monotonic and monotonically decreasing function.
在确定目标检测点的透明度参数之后，为了使第一子模型和第二子模型的视觉体验效果更好，可以将第一子模型上的目标检测点按照相对应的透明度参数进行显示，并将目标检测点与目标拍摄装置所属直线与第二子模型的交点按照相对应的透明度参数进行显示，以得到透明显示的效果。After determining the transparency parameters of the target detection points, in order to make the visual experience of the first sub-model and the second sub-model better, the target detection points on the first sub-model can be displayed according to the corresponding transparency parameters, and the The intersection of the target detection point and the line to which the target photographing device belongs and the second sub-model is displayed according to the corresponding transparency parameter, so as to obtain the effect of transparent display.
根据每个目标检测点，确定每个目标检测点的透明度参数，可以实现将第一子模型和第二子模型进行透明显示的效果。According to each target detection point, the transparency parameter of each target detection point is determined, and the effect of transparently displaying the first sub-model and the second sub-model can be realized.
例如，根据各目标检测点所对应的距离信息，可以在预先存储的每个距离信息与透明度参数的对应关系中，确定与距离信息相对应的透明度参数，可以包括第一子模型的透明度参数以及第二子模型的透明度参数，以便后续透明显示时使用。在确定目标拍摄角度下各目标检测点所对应的用于显示第一子模型和第二子模型的透明度参数后，基于上述透明度参数可以调节与第一子模型上各目标检测点所对应的待碰撞点的属性信息。For example, according to the distance information corresponding to each target detection point, the transparency parameter corresponding to the distance information may be determined in the pre-stored correspondence between each distance information and the transparency parameter, which may include the transparency parameter of the first sub-model and The transparency parameter of the second submodel for subsequent transparent display. After determining the transparency parameters for displaying the first sub-model and the second sub-model corresponding to each target detection point under the target shooting angle, the to-be-to-be-detected points corresponding to each target detection point on the first sub-model can be adjusted based on the above-mentioned transparency parameters. Attribute information of the collision point.
例如，所述当检测到第一子模型为半透明显示时，根据各目标检测点所对应的距离信息，确定与各目标检测点所对应的待碰撞点的透明度信息，包括：当检测到第二子模型为半透明显示时，根据与各目标检测点所对应的距离信息，按照预先建立的距离信息和透明度信息之间的对应关系，确定各目标检测点所对应的待碰撞点的透明度信息。For example, when it is detected that the first sub-model is translucent, the transparency information of the to-be-collision point corresponding to each target detection point is determined according to the distance information corresponding to each target detection point, including: when the first sub-model is detected When the two sub-models are displayed semi-transparently, according to the distance information corresponding to each target detection point, and according to the corresponding relationship between the pre-established distance information and transparency information, determine the transparency information of the to-be-collision point corresponding to each target detection point .
其中，可以预先建立距离信息和透明度参数之间的对应关系，可以根据对应关系确定各目标检测点的透明度参数。如，距离信息为5mm时，根据对应关 系确定透明度参数为0.5,；距离信息为10mm时，根据对应关系确定透明度参数为0.2。The corresponding relationship between the distance information and the transparency parameter may be established in advance, and the transparency parameter of each target detection point may be determined according to the corresponding relationship. For example, when the distance information is 5mm, the transparency parameter is determined to be 0.5 according to the corresponding relationship; when the distance information is 10mm, the transparency parameter is determined to be 0.2 according to the corresponding relationship.
也就是说，在确定距离信息后，可以根据距离信息和透明度参数对应关系，确定各目标检测点对应的透明度信息。That is to say, after the distance information is determined, the transparency information corresponding to each target detection point can be determined according to the corresponding relationship between the distance information and the transparency parameter.
S140、基于各待碰撞点的透明度信息，调整各待碰撞点的属性信息，以使所述第二子模型上的各待碰撞点基于所述属性信息进行透明显示。S140. Based on the transparency information of each point to be collided, adjust the attribute information of each point to be collided, so that each point to be collided on the second sub-model is transparently displayed based on the attribute information.
其中，待碰撞点为第二子模型上的点。针对各目标检测点，在确定当前目标检测点与拍摄装置连线后，可以与第二子模型碰撞得到待碰撞点。即，待碰撞点是在各目标检测点的相对拍摄角度下，第二子模型上与各目标检测点所对应的点。属性信息可以是待碰撞点的颜色属性，如，待碰撞点与对应目标检测点之间的距离信息越小，待碰撞点的颜色深度约深，透明显示效果越好；待碰撞点与对应目标检测点之间的距离信息越大，待碰撞点的颜色深度越浅，透明度显示效果相对弱一点，与实际理论相符。The point to be collided is a point on the second sub-model. For each target detection point, after it is determined that the current target detection point is connected to the photographing device, the point to be collided can be obtained by colliding with the second sub-model. That is, the point to be collided is a point corresponding to each target detection point on the second sub-model under the relative shooting angle of each target detection point. The attribute information can be the color attribute of the point to be collided. For example, the smaller the distance information between the point to be collided and the corresponding target detection point, the deeper the color depth of the point to be collided, and the better the transparent display effect; The greater the distance information between the detection points, the lighter the color depth of the point to be collided with, and the relatively weaker transparency display effect, which is consistent with the actual theory.
例如，在确定各目标检测点的透明度信息后，可以根据透明度信息调整与目标检测点所对应的第二碰撞点的颜色属性，如，距离信息越大，待碰撞点的颜色越深，反之越浅，此种方式实现了在外层半透明显示时，可以调整各目标检测点所对应的待碰撞点的颜色深度，进而实现透明显示。本实施例的技术方案，通过确定的目标拍摄角度，以及从顶点色和/或属性信息中调取投影系数值，目标检测点所对应的第一子模型和第二子模型之间的距离信息，进而确定透明度参数并进行显示，解决了以固定透明度显示值对第一子模型进行透明显示时透明显示与实际情况存在偏差而导致的透明显示效果不佳，用户体验较差的技术问题，根据实际情况调整透明度参数，使透明显示效果与实际理论效果相符，提高了用户体验。For example, after determining the transparency information of each target detection point, the color attribute of the second collision point corresponding to the target detection point can be adjusted according to the transparency information. For example, the greater the distance information, the darker the color of the point to be collided, and vice versa. In this way, when the outer layer is semi-transparently displayed, the color depth of the to-be-collision point corresponding to each target detection point can be adjusted, thereby realizing transparent display. In the technical solution of this embodiment, the distance information between the first sub-model and the second sub-model corresponding to the target detection point is obtained by determining the target shooting angle and retrieving the projection coefficient value from the vertex color and/or attribute information. , and then determine the transparency parameter and display it, which solves the technical problem of poor transparent display effect and poor user experience caused by the deviation between the transparent display and the actual situation when the first sub-model is transparently displayed with a fixed transparency display value. Adjust the transparency parameter according to the actual situation, so that the transparent display effect is consistent with the actual theoretical effect, and the user experience is improved.
在上述技术方案的基础上，所述基于各待碰撞点的透明度信息，调整各待碰撞点的属性信息，以使所述第二子模型上的各待碰撞点基于所述属性信息进行显示，包括：根据各待碰撞点的透明度信息，调整各待碰撞点的颜色深度值，以基于所述第二子模型上各待碰撞点的颜色深度值进行透明显示。其中，属性信息可以是颜色深度值。此时，由于第一子模型采用的是半透明材料，可以根据每个目标检测点对应的透明度参数，调整与各目标检测点所对应的第二碰撞点的颜色深度，如距离越近颜色深度值越大，反之，待碰撞点的颜色越浅。On the basis of the above technical solution, the attribute information of each point to be collided is adjusted based on the transparency information of each point to be collided, so that each point to be collided on the second sub-model is displayed based on the attribute information, The method includes: adjusting the color depth value of each point to be collided according to the transparency information of each point to be collided, so as to perform transparent display based on the color depth value of each point to be collided on the second sub-model. The attribute information may be a color depth value. At this time, since the first sub-model uses a translucent material, the color depth of the second collision point corresponding to each target detection point can be adjusted according to the transparency parameter corresponding to each target detection point. For example, the closer the distance, the color depth. The larger the value, the lighter the color of the point to be collided with.
需要说明的是，可以根据实际情况设置不同透明度参数所对应的颜色属性，即颜色深度值，在确定透明度参数后，可以根据透明度参数对应的颜色深度值调整各待碰撞点的颜色深度值。It should be noted that the color attributes corresponding to different transparency parameters, that is, the color depth value, can be set according to the actual situation. After the transparency parameter is determined, the color depth value of each point to be collided can be adjusted according to the color depth value corresponding to the transparency parameter.
例如，在确定每个目标检测点所对应的第一子模型和第二子模型之间的距离信息后，可以获取第一子模型和第二子模型的属性信息，结合属性信息和距离信息，综合来确定每个目标检测点所对应的透明度信息，从而使第一子模型和第二子模型透明显示。For example, after determining the distance information between the first sub-model and the second sub-model corresponding to each target detection point, the attribute information of the first sub-model and the second sub-model can be obtained, combining the attribute information and the distance information, The transparency information corresponding to each target detection point is determined comprehensively, so that the first sub-model and the second sub-model are transparently displayed.

Before determining the target reconstruction function corresponding to each target detection point according to the pre-received projection coefficient values of each target detection point in the spherical harmonic function of each basis function, the method further includes: determining the projection coefficient of each target detection point value. The specific implementation can refer to the following introduction, wherein, the technical terms that are the same as or corresponding to the above-mentioned embodiments are not repeated here.
如图3所示，所述方法包括：As shown in Figure 3, the method includes:

For the collision point information to be processed, the distance values of the current target collision in each direction are determined according to the current target detection point and the information of each collision point to be processed. According to the distance values of each target detection point in each direction, a distance function corresponding to each target detection point is determined.

其中，第一子模型与第二子模型是相对而言的，若应用场景为皮肤模型和衣服模型时，可以将衣服所对应的模型作为第一子模型，皮肤所对应的模型作为第二子模型。目标检测点可以是第一子模型上预先设置的检测点；也可以是将第一子模型上的预先设置的点划分为多个块，可以将每个块的中心点作为目标检测点；也可以是开发人员根据实际需求设置的检测点；当然，也可以是，第一子模型是由多个点构成的，可以将每个点作为目标检测点。距离函数是与每个目标检测点相对应的，即一个目标检测点对应一个距离函数。针对每个距离函数，可以理解为：可以根据某个目标检测点在空间中的每个方向上与第二子模型之间的相对距离信息确定出来的。Among them, the first sub-model and the second sub-model are relative. If the application scene is a skin model and a clothing model, the model corresponding to the clothes can be used as the first sub-model, and the model corresponding to the skin can be used as the second sub-model. Model. The target detection point may be a preset detection point on the first sub-model; it may also be that the preset point on the first sub-model is divided into a plurality of blocks, and the center point of each block may be used as the target detection point; or It can be a detection point set by the developer according to actual needs; of course, it can also be that the first sub-model is composed of multiple points, and each point can be used as a target detection point. The distance function corresponds to each target detection point, that is, a target detection point corresponds to a distance function. For each distance function, it can be understood as: it can be determined according to the relative distance information between a certain target detection point and the second sub-model in each direction in space.
由于是球面分布的距离函数，每个目标检测点在各方向与第二子模型之间 的距离，可以是：以目标检测点为球心，向空间中每个方向发射物理射线，确定各条物理射线与第二子模型的交点与目标检测点之间距离信息。Since it is a distance function of spherical distribution, the distance between each target detection point and the second sub-model in each direction can be: take the target detection point as the center of the sphere, emit physical rays in each direction in space, and determine each Distance information between the intersection of the physical ray and the second sub-model and the target detection point.

需要说明的是，确定不同目标检测点的球面分布距离函数是采用相同的方式，为了清楚的介绍本实施例技术方案，以确定其中一个目标检测点的球面分布函数为例来介绍。It should be noted that the same method is used to determine the spherical distribution distance function of different target detection points. In order to clearly introduce the technical solution of this embodiment, the spherical distribution function of one of the target detection points is determined as an example to introduce.
例如，可以以第一子模型上的一个目标检测点作为球心，向空间中的每个方向发射物理射线，确定各条物理射线与第二子模型的交点与目标检测点之间距离信息。若物理射线在该射线的方向上与第二子模型存在交点，则将该交点与目标检测点的距离作为目标检测点在该方向上与第二子模型之间的距离信息。若球形射线在该射线的方向上与第二子模型不存在交点，则可以将预设的最大距离信息作为目标检测点在该方向上与第二子模型之间的距离信息。For example, a target detection point on the first sub-model can be used as the center of the sphere, physical rays can be emitted in every direction in space, and the distance information between the intersection of each physical ray and the second sub-model and the target detection point can be determined. If the physical ray has an intersection with the second sub-model in the direction of the ray, the distance between the intersection and the target detection point is used as the distance information between the target detection point and the second sub-model in the direction. If the spherical ray does not have an intersection with the second sub-model in the direction of the ray, the preset maximum distance information may be used as the distance information between the target detection point and the second sub-model in this direction.
根据目标检测点在空间中的每个方向上的确定的距离信息，可以确定目标检测点的球面分布的距离函数，例如：目标检测点A的球面分布距离函数为According to the determined distance information of the target detection point in each direction in space, the distance function of the spherical distribution of the target detection point can be determined. For example, the spherical distribution distance function of the target detection point A is:
Figure PCTCN2021131500-appb-000001
Figure PCTCN2021131500-appb-000001
其中，i表示第i个方向，F(i)表示第i个方向上的距离信息，dist_i表示具体的距离信息，n表示方向的总数量。Among them, i represents the ith direction, F(i) represents the distance information in the ith direction, dist_i represents the specific distance information, and n represents the total number of directions.
需要说明的是，每个目标检测点的球面分布的距离函数是一个复合函数，该复合函数中子函数的个数可以根据预设的采样数量确定，默认的可以是16×32的精度，即复合函数中包含512个子函数。当采样数量越大时，复合函数中的子函数数量越多，精度越高。具体的采样数量可以根据实际需求来确定。It should be noted that the distance function of the spherical distribution of each target detection point is a composite function, and the number of sub-functions in the composite function can be determined according to the preset number of samples. The default can be 16×32 precision, that is, The composite function contains 512 sub-functions. When the number of samples is larger, the larger the number of sub-functions in the composite function, the higher the precision. The specific sampling quantity can be determined according to actual needs.
还需要说明的是，确定不同目标检测点的投影系数值是采用相同的方式，为了清楚的介绍本实施例技术方案，以确定其中一个目标检测点的的投影系数值为例来介绍。It should also be noted that the same method is used to determine the projection coefficient values of different target detection points. In order to clearly introduce the technical solution of this embodiment, the projection coefficient value of one of the target detection points is determined as an example.
其中，球谐函数由多个基函数构成，可以使用基函数对每个距离函数进行处理。球谐函数不同的阶数对应的基函数数量不同，二阶球谐函数包含4个基函数，三阶球谐函数包含9个基函数，四阶球谐函数包含16个基函数等。投影 系数值是根据球谐函数中的基函数对距离函数进行处理后，得到的系数值，其系数值的数量与基函数的数量相同。根据球谐函数与其对应的多个基函数可以对目标检测点的球面分布距离函数进行压缩，以得到投影系数值。Among them, the spherical harmonic function is composed of multiple basis functions, and each distance function can be processed by using the basis function. Different orders of spherical harmonics correspond to different numbers of basis functions. The second-order spherical harmonics include 4 basis functions, the third-order spherical harmonics include 9 basis functions, and the fourth-order spherical harmonics include 16 basis functions. The projection coefficient value is the coefficient value obtained by processing the distance function according to the basis function in the spherical harmonic function, and the number of coefficient values is the same as that of the basis function. According to the spherical harmonic function and its corresponding multiple basis functions, the spherical distribution distance function of the target detection point can be compressed to obtain the projection coefficient value.
示例性的：球谐函数为二阶，即包括4个基函数，那么将目标检测点所对应的距离函数输入至该球谐函数中可以得到4个投影系数值，以此将距离函数压缩为4个投影系数值。Exemplary: the spherical harmonic function is second-order, that is, it includes 4 basis functions, then inputting the distance function corresponding to the target detection point into the spherical harmonic function can obtain 4 projection coefficient values, so as to compress the distance function into 4 projection coefficient values.
需要说明的是，球谐函数的阶数越高，在重建时重建出来的球形与实际球形的相似度就越高，因此开发人员可以根据实际需求选择不同阶数的球谐函数。越高阶的球谐函数包含的基函数越多，在后续根据球谐函数以及投影系数值还原距离函数时的还原程度越高。It should be noted that the higher the order of the spherical harmonic function, the higher the similarity between the reconstructed sphere and the actual sphere during reconstruction, so developers can choose spherical harmonic functions of different orders according to actual needs. The higher-order spherical harmonic function contains more basis functions, and the degree of restoration of the distance function is higher in the subsequent restoration of the distance function according to the spherical harmonic function and the projection coefficient value.
例如，在确定球谐函数的具体阶数后，可以将目标检测点的球面分布的距离函数输入至球谐函数中，基于球谐函数中的基函数对距离函数进行处理，以获得上述距离函数在每个基函数上的投影系数值。由此可知，投影系数值的数量与球谐函数中的基函数的数量相等。For example, after determining the specific order of the spherical harmonic function, the distance function of the spherical distribution of the target detection point can be input into the spherical harmonic function, and the distance function is processed based on the basis function in the spherical harmonic function to obtain the above distance function. The projection coefficient values on each basis function. It follows that the number of projection coefficient values is equal to the number of basis functions in spherical harmonics.
需要说明的是，不同目标检测点的球面分布的距离函数可以相同也可以不同，当不同目标检测点在空间中每个方向上的距离信息都相同时，不同目标检测点所对应的距离函数相同，当不同目标检测点在空间中每个方向上的距离信息存在至少一个不同时，不同目标检测点所对应的距离函数不同，其中，距离函数是否相同是根据目标检测点在空间中每个方向上的距离信息来确定的。将不同的距离函数输入至预先设置的球谐函数进行处理后，得到的投影系数值不同。It should be noted that the distance functions of the spherical distribution of different target detection points can be the same or different. When the distance information of different target detection points in each direction in space is the same, the distance functions corresponding to different target detection points are the same. , when there is at least one difference in the distance information of different target detection points in each direction in space, the distance functions corresponding to different target detection points are different, and whether the distance function is the same is based on the target detection points in each direction in space. The distance information on it is determined. After inputting different distance functions into the preset spherical harmonic function for processing, the obtained projection coefficient values are different.
S320、将每个目标检测点的投影系数值按照空间位置关系对应存储至至少一副图像中，并将所述至少一副图像存储至目标位置，以从所述目标位置获取所有目标检测点在对应阶球谐函数上的投影系数值。S320. Store the projection coefficient value of each target detection point in at least one image according to the spatial position relationship, and store the at least one image in the target position, so as to obtain all target detection points at the target position from the target position. The value of the projection coefficient on the corresponding spherical harmonic function.
在上述技术方案的基础上，在确定各目标检测点所对应的投影系数值之后，还包括，将投影系数值存储至至少一副图像中，以从至少一副图像中获取相应目标检测点的投影系数值，从而重建出相应的目标重建函数。Based on the above technical solution, after determining the projection coefficient value corresponding to each target detection point, the method further includes: storing the projection coefficient value in at least one image, so as to obtain the corresponding target detection point from the at least one image. Projection coefficient value, so as to reconstruct the corresponding objective reconstruction function.
例如，将每个目标检测点的投影系数值按照空间位置关系对应存储至至少一副图像中，并将所述至少一副图像存储至目标位置，以从所述目标位置获取所有目标检测点在对应阶球谐函数上的投影系数值。For example, the projection coefficient value of each target detection point is correspondingly stored in at least one image according to the spatial position relationship, and the at least one image is stored in the target position, so as to obtain all target detection points in the target position from the target position. The value of the projection coefficient on the corresponding spherical harmonic function.
需要说明的是，存储不同目标检测点的投影系数值的方式是相同的，可以以存储某个目标检测点所对应的投影系数值为例来介绍。It should be noted that the method of storing the projection coefficient values of different target detection points is the same, and it can be introduced by taking the storage of the projection coefficient value corresponding to a certain target detection point as an example.
其中，若球谐函数是二阶的，则基函数的数量可以有四个，通过球谐函数 中的基函数对距离函数进行处理后，可以得到四个投影系数值。可以将投影系数值按照空间坐标位置信息存储至图像中，例如，投影系数值有四个，则可以采用四幅图像来存储投影系数值，每幅图像中的每个像素点存储一个投影系数值。可以将至少一副图像存储至引擎中，可以将存储至引擎中的位置作为目标位置。将图像存储至目标位置的好处在于：可以从目标位置获取存储的投影系数值，以便根据投影系数值构建出重建函数。Among them, if the spherical harmonic function is second-order, the number of basis functions can be four, and after the distance function is processed by the basis functions in the spherical harmonic function, four projection coefficient values can be obtained. The projection coefficient values can be stored in the image according to the spatial coordinate position information. For example, if there are four projection coefficient values, four images can be used to store the projection coefficient values, and each pixel in each image stores a projection coefficient value. At least one image may be stored in the engine, and the location stored in the engine may be used as the target location. The advantage of storing the image to the target location is that the stored projection coefficient values can be obtained from the target location so that a reconstruction function can be constructed from the projection coefficient values.
例如，可以根据投影系数值的数量，确定图像的数量，并将投影系数值按照空间坐标信息存储至图像中的相应像素点。For example, the number of images may be determined according to the number of projection coefficient values, and the projection coefficient values may be stored in corresponding pixel points in the image according to the spatial coordinate information.
示例性的，球谐函数的阶数为3阶，则球谐函数中基函数的数量为9个，则每个目标检测点存在9个投影系数值。此时，可以确定九幅图像，并按照空间坐标信息将每个目标检测点的九个投影系数值存储至每幅图像中的对应像素点中。Exemplarily, if the order of the spherical harmonic function is 3, then the number of basis functions in the spherical harmonic function is 9, and each target detection point has 9 projection coefficient values. At this time, nine images can be determined, and the nine projection coefficient values of each target detection point can be stored in the corresponding pixel points in each image according to the spatial coordinate information.
需要说明的，也可以将投影系数值存储至顶点色中。可以将第一子模型上的每个目标检测点作为顶点色，每个目标检测点对应有像素通道，即RGBA四个通道，可以在每个通道中存储该目标检测点的投影系数值。属性信息可以是每个目标检测点所对应的可扩展信息，例如：UV，即u,v纹理贴图坐标。目标检测点所对应的顶点色以及当前目标检测点的属性信息可以共同使用来存储投影系数值。It should be noted that the projection coefficient value can also be stored in the vertex color. Each target detection point on the first sub-model can be used as a vertex color, each target detection point corresponds to a pixel channel, that is, four RGBA channels, and the projection coefficient value of the target detection point can be stored in each channel. The attribute information can be scalable information corresponding to each target detection point, for example: UV, ie u, v texture map coordinates. The vertex color corresponding to the target detection point and the attribute information of the current target detection point can be used together to store the projection coefficient value.
例如，将当前目标检测点所对应的投影系数值存储至与当前目标检测点所对应的顶点色中时，可以是按R，G，B以及A四个通道分别存储4个投影系数值，并且，可以根据投影系数值的数量确定需要顶点色的数量。也可以在一个顶点色中存储4个投影系数值，并将剩余的投影系数值存储至与当前目标检测点所对应的UV坐标中，上述方式可以减少顶点色的使用，并且便于投影系数值的存储以及后续的调取和使用。For example, when the projection coefficient value corresponding to the current target detection point is stored in the vertex color corresponding to the current target detection point, four projection coefficient values can be stored respectively according to the four channels of R, G, B and A, and , the number of vertex colors required can be determined according to the number of projection coefficient values. It is also possible to store 4 projection coefficient values in one vertex color, and store the remaining projection coefficient values in the UV coordinates corresponding to the current target detection point. The above method can reduce the use of vertex colors and facilitate the calculation of projection coefficient values. storage and subsequent recall and use.
例如，还可以将目标检测点所对应的顶点色与当前目标检测点所对应的UV坐标共同使用来存储投影系数值，例如：若存储9个投影系数值，可以使用两个顶点色存储8个投影系数值，并将剩余的1个投影系数值存储至与当前目标检测点所对应的UV坐标中。For example, the vertex color corresponding to the target detection point and the UV coordinate corresponding to the current target detection point can also be used together to store the projection coefficient value. For example, if 9 projection coefficient values are stored, two vertex colors can be used to store 8 projection coefficient value, and store the remaining 1 projection coefficient value in the UV coordinate corresponding to the current target detection point.
当投影系数值完成存储后，可以根据当前目标检测点的索引坐标导入引擎中的目标位置进行存储，以根据目标检测点从引擎中调取与当前目标检测点所对应投影系数值，以根据投影系数值重建后的目标距离信息，确定各目标检测点的透明度参数，进而基于各透明度参数显示第一子模型和第二子模型。After the projection coefficient value is stored, it can be imported into the target position in the engine according to the index coordinates of the current target detection point for storage, so that the projection coefficient value corresponding to the current target detection point can be retrieved from the engine according to the target detection point. The target distance information reconstructed by the coefficient value determines the transparency parameter of each target detection point, and then displays the first sub-model and the second sub-model based on each transparency parameter.
S330、针对各目标检测点，从目标位置调取至少一副图像，并确定当前目 标检测点在至少一副图像中的目标像素点位置，并根据调取的各投影系数值，得到当前目标检测点所对应的目标重建函数。S330. For each target detection point, retrieve at least one image from the target position, determine the target pixel position of the current target detection point in the at least one image, and obtain the current target detection point according to the retrieved projection coefficient values The target reconstruction function corresponding to the point.
在实际应用过程中，若需要透明显示第一子模型上的每个目标检测点时，需要确定各目标检测点在相对拍摄角度下的距离信息，进而根据距离信息确定透明度参数。在确定各目标检测点在相对拍摄角度下的距离信息时，可以根据目标位置存储的投影系数值重建出与各目标检测点所对应的重建函数，以便将相对拍摄角度输入至相应的重建函数中，得到各目标检测点所对应的距离信息。In the actual application process, if each target detection point on the first sub-model needs to be displayed transparently, the distance information of each target detection point at the relative shooting angle needs to be determined, and then the transparency parameter is determined according to the distance information. When determining the distance information of each target detection point under the relative shooting angle, the reconstruction function corresponding to each target detection point can be reconstructed according to the projection coefficient value stored at the target position, so that the relative shooting angle can be input into the corresponding reconstruction function , to obtain the distance information corresponding to each target detection point.
例如，针对每个目标检测点，可以获取当前目标检测点空间坐标信息，可以根据空间坐标信息，确定当前目标检测点在每一幅图像中的目标像素点位置，可以从每一幅图像的目标像素点位置获取存储的投影系数值。根据球谐函数对各存储的投影系数值进行重建处理，得到当前目标检测点向空间中每个方向发射物理射线时，各物理射线所对应当前目标检测点与第二子模型碰撞时，当前目标检测点与待碰撞点之间的距离信息，并根据各距离信息得到的距离函数，即每个目标检测点所对应的目标重建函数为距离函数。For example, for each target detection point, the spatial coordinate information of the current target detection point can be obtained, and the target pixel position of the current target detection point in each image can be determined according to the spatial coordinate information. The pixel position gets the stored projection coefficient value. Reconstruct each stored projection coefficient value according to the spherical harmonic function, and obtain when the current target detection point emits physical rays in each direction in the space, when the current target detection point corresponding to each physical ray collides with the second sub-model, the current target detection point The distance information between the detection point and the point to be collided, and the distance function obtained according to each distance information, that is, the target reconstruction function corresponding to each target detection point is the distance function.

S360、当检测到第一子模型为半透明显示时，根据各目标检测点所对应的距离信息，确定与各目标检测点所对应的待碰撞点的透明度信息。S360. When it is detected that the first sub-model is translucent display, according to the distance information corresponding to each target detection point, determine the transparency information of the to-be-collision point corresponding to each target detection point.
S370、基于各待碰撞点的透明度信息，调整各待碰撞点的属性信息，以使所述第二子模型上的各待碰撞点基于所述属性信息进行透明显示。S370.

图4为本申请另一实施例提供的一种确定透明度的方法的流程示意图。在前述实施例的基础上，确定距离函数的具体确定方式，可以参见本实施例技术方案。其中与上述各实施例相同或相应的术语的解释在此不再赘述。FIG. 4 is a schematic flowchart of a method for determining transparency according to another embodiment of the present application. On the basis of the foregoing embodiment, for the specific determination method of determining the distance function, reference may be made to the technical solution of this embodiment. The explanations of terms that are the same as or corresponding to the above embodiments are not repeated here.
如图4所示，所述方法包括：As shown in Figure 4, the method includes:
S410、对第一子模型上的各目标检测点，确定当前目标检测点向各方向发 射物理射线透过第二子模型时的各待处理碰撞点信息。S410. For each target detection point on the first sub-model, determine the information of each to-be-processed collision point when the current target detection point emits physical rays in all directions and passes through the second sub-model.
其中，各待处理碰撞点的信息可以包括各待碰撞点的位置信息，例如：空间坐标信息等。例如，以当前目标检测点为球心，向空间中的任意方向发射物理射线，记录各物理射线与所述第二子模型相交时的待处理碰撞点，并确定各待处理碰撞点与目标检测点之间的距离值。The information of each collision point to be processed may include position information of each collision point to be collided, such as spatial coordinate information and the like. For example, take the current target detection point as the center of the sphere, emit physical rays in any direction in space, record the collision points to be processed when each physical ray intersects the second sub-model, and determine the collision points to be processed and the target detection point. Distance value between points.
例如，可以是基于第一子模型上的各目标检测点向每个方向发射物理射线，上述各条物理射线可能会透过第二子模型，当物理射线透过第二子模型时，确定物理射线与第二子模型存在待处理碰撞点，并将物理射线与第二子模型的交点作为待处理碰撞点。待处理碰撞点信息可以是用于描述该点位置的信息，如空间坐标信息。因此，根据待处理碰撞点可以确定与待处理碰撞点相对应的空间坐标信息为待处理碰撞点信息。For example, physical rays may be emitted in each direction based on each target detection point on the first sub-model, and the above-mentioned physical rays may pass through the second sub-model. There is a collision point to be processed between the ray and the second sub-model, and the intersection of the physical ray and the second sub-model is used as the collision point to be processed. The collision point information to be processed may be information used to describe the position of the point, such as spatial coordinate information. Therefore, according to the collision point to be processed, it can be determined that the spatial coordinate information corresponding to the collision point to be processed is the information of the collision point to be processed.
在本实施例中，确定待处理碰撞点信息可以是：可以以当前目标检测点为球心，向空间任意方向发射物理射线，确定各物理射线透过第二子模型时的待处理碰撞点信息。In this embodiment, determining the information of the collision point to be processed may be: taking the current target detection point as the center of the sphere, emitting physical rays in any direction in space, and determining the information of the collision point to be processed when each physical ray passes through the second sub-model .
例如，可以将从第一子模型上的各目标检测点向每个方向发射物理射线看作是以当前目标检测点为球心，向球面的每个方向发射物理射线。若物理射线透过第二子模型，则将物理射线与第二子模型交点的空间坐标信息作为待处理碰撞点信息。For example, the emission of physical rays in each direction from each target detection point on the first sub-model can be regarded as taking the current target detection point as the center of the sphere, and emitting physical rays in each direction of the spherical surface. If the physical ray passes through the second sub-model, the spatial coordinate information of the intersection of the physical ray and the second sub-model is used as the collision point information to be processed.
S420、根据当前目标检测点与各待处理碰撞点信息，确定当前目标检测点在各方向上与所述第二子模型之间的距离信息。S420: Determine the distance information between the current target detection point and the second sub-model in all directions according to the current target detection point and the information of each collision point to be processed.
当物理射线与第二子模型存在待处理碰撞点时，则确定待处理碰撞点信息与当前目标检测点的距离信息。When there is a collision point to be processed between the physical ray and the second sub-model, the distance information between the information of the collision point to be processed and the current target detection point is determined.
例如，当存在待处理碰撞点时，可以根据当前目标检测点的空间坐标信息以及待处理碰撞点的空间坐标信息，使用空间中两点之间距离的计算公式计算得出待处理碰撞点信息与当前目标检测点的距离信息。For example, when there is a collision point to be processed, according to the spatial coordinate information of the current target detection point and the spatial coordinate information of the collision point to be processed, the calculation formula of the distance between two points in the space can be used to calculate the difference between the information of the collision point to be processed and the spatial coordinate information of the collision point to be processed. The distance information of the current target detection point.
当物理射线与第二子模型不存在待处理碰撞点时，则将与待处理碰撞点所对应的距离信息设置为设定值。When there is no collision point to be processed between the physical ray and the second sub-model, the distance information corresponding to the collision point to be processed is set as a set value.
例如，若物理射线不透过第二子模型，如，发射的物理射线与第二子模型是平行的或者是朝着背向第二子模型的方向发射的物理射线，此时物理射线与第二子模型之间不存在碰撞点，可以将此时的待处理碰撞信息设定为设定值。该设定值可以是待处理碰撞点信息与当前目标检测点的最大距离信息。For example, if the physical ray does not pass through the second sub-model, for example, the emitted physical ray is parallel to the second sub-model or the physical ray emitted in the direction away from the second sub-model, at this time, the physical ray and the first There is no collision point between the two sub-models, and the collision information to be processed at this time can be set as the set value. The set value may be the maximum distance information between the collision point information to be processed and the current target detection point.
根据与每个待处理碰撞点所对应的距离信息或设定值，确定当前目标检测点在各方向上与第二子模型之间的距离信息。According to the distance information or set value corresponding to each collision point to be processed, the distance information between the current target detection point and the second sub-model in each direction is determined.
例如，基于上述两种情况，可以确定当前目标检测点发射的各条物理射线所对应的距离信息或设定值，并将距离信息或设定值作为当前目标检测点在各方向上与第二子模型之间的距离信息。For example, based on the above two situations, the distance information or setting value corresponding to each physical ray emitted by the current target detection point can be determined, and the distance information or setting value can be used as the current target detection point in all directions with the second Distance information between submodels.
S430、根据每个目标检测点在各方向上的距离信息，确定相应目标检测点的球面分布的距离函数。S430 , according to the distance information of each target detection point in each direction, determine the distance function of the spherical distribution of the corresponding target detection point.
例如，将每个目标检测点在空间中每个方向上的距离信息作为目标检测点的球面分布的距离函数中的一个子函数，可以得到目标检测点的球面分布的距离函数。该距离函数中的子函数数量与目标检测点在球面每个方向上的距离信息数量相同。For example, taking the distance information of each target detection point in each direction in space as a sub-function of the distance function of the spherical distribution of the target detection point, the distance function of the spherical distribution of the target detection point can be obtained. The number of sub-functions in this distance function is the same as the amount of distance information of the target detection point in each direction of the sphere.
需要说明的是，为了提高精度，可以增加子函数的数量，即增加物理射线的密度，具体物理射线的数量可以根据实际需求来确定。It should be noted that, in order to improve the accuracy, the number of sub-functions can be increased, that is, the density of physical rays can be increased, and the specific number of physical rays can be determined according to actual requirements.
S440、确定球谐函数的阶数以及距离函数，确定基函数的数量和基函数的表示方式。S440. Determine the order of the spherical harmonic function and the distance function, and determine the number of basis functions and the representation of the basis functions.
其中，不同阶数的球谐函数中包含的基函数数量不同，例如：二阶球谐函数包含4个基函数，三阶球谐函数包含9个基函数，四阶球谐函数包含16个基函数等。球谐函数的阶数越高，在后续使用重建函数进行重建时的效果会越好，具体的阶数需要根据实际需求来设定。Among them, the number of basis functions contained in spherical harmonics of different orders is different. For example, the second-order spherical harmonic function contains 4 basis functions, the third-order spherical harmonic function contains 9 basis functions, and the fourth-order spherical harmonic function contains 16 basis functions. function etc. The higher the order of the spherical harmonic function, the better the effect of subsequent reconstruction using the reconstruction function. The specific order needs to be set according to actual needs.
例如，根据需求确定球谐函数的阶数为a，那么可以确定球谐函数中的基函数数量为a^2。根据距离函数与投影系数值的关系可以确定每个基函数的表示方式。For example, if the order of the spherical harmonic function is determined to be a according to the requirements, then the number of basis functions in the spherical harmonic function can be determined to be a^2. The representation of each basis function can be determined according to the relationship between the distance function and the value of the projection coefficient.
S450、针对每个目标检测点，基于球谐函数中的各基函数对当前目标检测点的距离函数进行处理，得到当前目标检测点的投影系数值。S450. For each target detection point, process the distance function of the current target detection point based on each basis function in the spherical harmonic function to obtain a projection coefficient value of the current target detection point.
需要说明的是，确定不同目标检测点的投影系数值是采用相同的方式，为了清楚的介绍本实施例技术方案，以确定其中一个目标检测点的的投影系数值为例来介绍。It should be noted that the same method is used to determine the projection coefficient values of different target detection points. In order to clearly introduce the technical solution of this embodiment, the projection coefficient value of one of the target detection points is determined as an example.
其中，投影系数值的数量与基函数的数量相同。投影系数值是使用预先设置的球谐函数中的每个基函数对距离函数进行计算确定的值。where the number of projection coefficient values is the same as the number of basis functions. The projection coefficient value is a value determined by calculating the distance function using each basis function of the preset spherical harmonic functions.
例如，基于每一个基函数对目标检测点的距离函数进行处理都可以得到与该基函数对应的投影系数值，因此，投影系数值的数量与基函数的数量相同。将目标检测点的距离函数输入至球谐函数的每个基函数中，可以获得上述距离函数在每个基函数上的投影系数值。For example, by processing the distance function of the target detection point based on each basis function, a projection coefficient value corresponding to the basis function can be obtained. Therefore, the number of projection coefficient values is the same as the number of basis functions. By inputting the distance function of the target detection point into each basis function of the spherical harmonic function, the projection coefficient value of the above distance function on each basis function can be obtained.
需要说明的是，每个目标检测点的球面分布的距离函数不同，将不同的距 离函数输入至预先设置的球谐函数进行处理后，得到的投影系数值不同。It should be noted that the distance functions of the spherical distribution of each target detection point are different, and after inputting different distance functions into the preset spherical harmonic function for processing, the obtained projection coefficient values are different.
