Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The embodiment of the application provides a picture rendering method, a picture rendering device, a storage medium and electronic equipment.
The screen rendering device may be specifically integrated in an electronic device. The electronic device may be a terminal or a server. For example, the terminal may be a mobile phone, a tablet Computer, an intelligent bluetooth device, a notebook Computer, or a Personal Computer (PC).
The following are detailed below. The numbers in the following examples are not intended to limit the order of preference of the examples.
In this embodiment, a screen rendering method is provided, where an execution subject of each step included in the method may be a server or a terminal, and execution subjects of different steps may be the same or different. As shown in fig. 1, the method for rendering a screen includes the following steps:
101. a first camera distance of a target three-dimensional model in the virtual scene relative to a plane where the virtual camera is located and a second camera distance of the two-dimensional model relative to the plane are obtained respectively.
The virtual scene refers to a three-dimensional scene which needs to use a picture rendering technology, namely a three-dimensional virtual scene. For example, the virtual scene may be a network game scene, a network animation scene, and the like.
In this embodiment, the number of the target three-dimensional models may be one or more. The target three-dimensional model can be a three-dimensional object with a relatively fixed position in a virtual scene, such as a three-dimensional model of furniture articles like chairs, tables, sofas, boxes and the like. The two-dimensional model may be a two-dimensional map with variable positions (especially freely movable) placed in a three-dimensional virtual scene, such as a two-dimensional paper person, a two-dimensional paper car, and the like.
In this embodiment, the virtual camera may be considered to be an observer of the screen. When the distance between the three-dimensional model and the virtual camera is calculated, the three-dimensional model can be regarded as a whole to calculate the distance between the three-dimensional model and the plane where the virtual camera is located, and the distances between each pixel point in the three-dimensional model and the virtual camera are not calculated. Referring to fig. 2, the dotted line is considered as the plane of the virtual camera (i.e., the light incident surface from the viewer's perspective), which may be perpendicular to the horizontal plane. Then, the first camera distance of the target three-dimensional model relative to the plane where the virtual camera is located, namely, the vertical distance from the target three-dimensional model to the plane; the second camera distance of the two-dimensional model relative to the plane in which the virtual camera is located means the perpendicular distance of the two dimensions to the plane.
In practical application, the manner of obtaining the distance between the three-dimensional model and the virtual camera may be various, and may be specifically selected according to actual requirements. For example, the distance between the three-dimensional model and the virtual camera may be calculated by using the position of the center point of the three-dimensional model (i.e., the position point with the same distance to the periphery of the model) as the position of the entire model. That is, in some embodiments, when obtaining the first camera distance of the three-dimensional model of the object in the virtual scene relative to the plane where the virtual camera is located, the following process may be included:
determining the position of a central point of the target three-dimensional model;
and taking the distance between the central point position and the virtual camera as the first camera distance of the target three-dimensional model relative to the plane where the virtual camera is located.
For another example, the distance between the three-dimensional model and the virtual camera may be calculated by using the position of the point closest to the virtual camera in the three-dimensional model as the position of the entire model. That is, in some embodiments, when obtaining the first camera distance of the three-dimensional model of the object in the virtual scene relative to the plane where the virtual camera is located, the following process may be included:
determining the distance between each pixel point in the target three-dimensional model and the virtual camera to obtain a distance set;
and taking the shortest distance in the distance set as the first camera distance of the target three-dimensional model relative to the plane where the virtual camera is located.
In addition, the position of the point farthest from the virtual camera in the three-dimensional model can be used as the position of the whole model, so that the distance between the three-dimensional model and the virtual camera can be calculated.
In this embodiment, a three-dimensional model in a screen may be controlled to be displayed by using a Stencil Buffer. The stereo Buffer is a Buffer for recording object information used by a GPU (graphics Processing Unit), and can control the display of an object on each pixel when rendering a screen. Since the Stencil Buffer generally has 8 bits, if the number of the two-dimensional models is less than or equal to 8, 0-7 serial numbers can be allocated in sequence.
In some embodiments, when the number of the two-dimensional models in the virtual scene exceeds a preset number, the two-dimensional models may be grouped according to the position of each two-dimensional model in the virtual scene to divide the two-dimensional models into models of different model types, and the front-back position relationship between the two-dimensional models and the target three-dimensional model may be set according to the divided model types. Specifically, the anteroposterior positional relationship between the two-dimensional model and the target three-dimensional model belonging to the same model type may be set to be the same. That is, for a two-dimensional model of the same model type, the anteroposterior positional relationship between it and the three-dimensional model is the same.
In specific implementation, two-dimensional models with relatively close positions can be divided into the same model type according to the distance relation of the positions.
In order to achieve better rendering effect, the Buffer space provided by the Stencil Buffer can be fully utilized, and the number of the packets is maximized. That is, the two-dimensional model may be divided into models of different model types to obtain the preset number of model types. For example, if the number of two-dimensional models exceeds 8, the two-dimensional models may be clustered to be divided into 8 categories, and then 0 to 7 serial numbers may be assigned according to the divided categories. That is, when all the two-dimensional models are divided into different model types according to the positions of the two-dimensional models in the virtual scene, the virtual scene may be specifically divided into a preset number of regions along the view direction of the virtual camera, and the two-dimensional models located in the same region may be divided into the same model type.
For example, referring to fig. 3, a method of dividing a region may be employed to divide a scene into 8 regions along the direction of a camera. The two-dimensional model characters in the same region can be assigned with the same serial number and share the same digit on the Stencil Buffer, so that more two-dimensional model characters are supported.
102. And determining the front-back position relation of the target three-dimensional model and the two-dimensional model according to the first camera distance and the second camera distance.
In this embodiment, in order to avoid the problem of object insertion display caused by comparing the front-back relationship between the three-dimensional model and the two-dimensional model according to the depth information at the pixel level, the three-dimensional model is regarded as a whole to calculate the camera distance, so that the camera distances of all the pixel points on the three-dimensional model are kept consistent, and all the pixel points on the three-dimensional model are ensured to be positioned in front of or behind the two-dimensional model at the same time.
Specifically, when the first camera distance is greater than the second camera distance, the target three-dimensional model is determined to be behind the two-dimensional model; when the first camera distance is less than the second camera distance, the target three-dimensional model is determined to precede the two-dimensional model.
It should be noted that, if the first camera distance is equal to the second camera distance, returning to the essence of the camera distance, when the first camera distance is calculated based on the model center point, the target three-dimensional model may be arbitrarily determined to be located behind or in front of the two-dimensional model; when the first camera distance is calculated based on a point in the model closest to the plane where the virtual camera is located, the target three-dimensional model may be arbitrarily determined to be located behind the two-dimensional model; when the first camera distance is calculated based on the point in the model that is furthest from the plane in which the virtual camera lies, the target three-dimensional model may be arbitrarily determined to be located before the two-dimensional model.
103. And determining the region of the target three-dimensional model to be drawn based on the front-back position relation.
In some embodiments, when determining the region where the target three-dimensional model and the two-dimensional model need to be drawn based on the front-back position relationship, the region where the target three-dimensional model and the two-dimensional model need to be drawn may be determined according to preset Mask (Mask) information and the front-back position relationship. The mask information may define an area of the scene to be rendered. Specifically, when determining a region to be drawn in the target three-dimensional model, the following process may be specifically included:
acquiring a third camera distance of each pixel point in the target three-dimensional model relative to a plane where the virtual camera is located;
when the first camera distance is larger than the second camera distance, determining an area to be drawn according to pixel points of the target three-dimensional model, of which the third camera distance is larger than the first camera distance, and preset mask information;
and when the first camera distance is smaller than the second camera distance, determining the area to be drawn according to the pixel point of which the third camera distance is smaller than the first camera distance in the target three-dimensional model and preset mask information.
The distance of each pixel point in the target three-dimensional model relative to the third camera of the plane where the virtual camera is located is equivalent to the depth of each pixel point relative to the plane where the virtual camera is located.
And when the first camera distance is greater than the second camera distance, the target three-dimensional model is positioned behind the two-dimensional model, and the part of the target three-dimensional model inserted in front of the two-dimensional model is not drawn. At this time, a region to be rendered in the scene picture may be determined based on the preset mask information, and a local region formed by pixel points (i.e., pixel points located behind the central point) having a depth value greater than the first camera distance in the target three-dimensional model located in the region range is determined as the region to be drawn.
And when the first camera distance is smaller than the second camera distance, the target three-dimensional model is positioned in front of the two-dimensional model, and the part of the target three-dimensional model inserted behind the two-dimensional model is not drawn. At this time, a region to be rendered in the scene picture may be determined based on the preset mask information, and a local region formed by pixel points (i.e., pixel points located before the central point) having a depth value smaller than the first camera distance in the target three-dimensional model located in the region range is determined as a region to be drawn.
In this embodiment, when determining the context, the camera distance is used instead of the depth information because the depth information is at the pixel level and the depths of different places on the same object are different, which may cause a part of the object to be located in front of the person and another part to be located behind the person, resulting in a puncturing effect (refer to the left image of fig. 4). And the information of the camera distance on the object is consistent, so that the object can be ensured to be positioned in front of or behind the person at the same time, and when the distance between the object and the camera is calculated by selecting the central point, the camera distances of other points on the object and the central point can be ensured to be consistent, so that the interpenetration of the objects is avoided, and a better shielding effect is achieved (refer to a right side diagram of fig. 4).
104. And performing picture rendering on an area needing to be drawn in the virtual scene.
Specifically, the region to be drawn is colored based on preset rendering parameters, and the depth information of the region to be drawn relative to the virtual camera is written into a depth buffer, so as to realize the picture rendering of the virtual scene.
In practical application, for some scenes where a more complex three-dimensional model is constructed to interact with a two-dimensional model, the three-dimensional model is not absolutely positioned before or behind the two-dimensional model. For example, taking a three-dimensional model as a three-dimensional seat model with armrests as an example, when a two-dimensional paper sheet person sits on the three-dimensional seat model and a hand of the two-dimensional paper sheet person is placed on the outer side of the armrests of the three-dimensional seat model, if the constructed scene is viewed from the side, the three-dimensional seat model should be displayed sequentially from near to far: two-dimensional paper people's hands, the armrests of the three-dimensional seat model, and other visible parts, two-dimensional paper people's body parts. At this time, the camera distance cannot be calculated by taking the three-dimensional seat model as a whole, so that the problem that the display effect is not consistent with the actual situation due to the fact that the three-dimensional seat model is behind the two-dimensional paper people because the two-dimensional paper people are closer to the camera and the whole three-dimensional seat model is shielded is solved.
Based on the scheme, the three-dimensional model with the complex structure can be split into the plurality of three-dimensional models with the simple structures, the camera distance of each three-dimensional model with the simple structure is calculated, and the front-back position relation with other two-dimensional models is determined according to the camera distance, so that the problem that the display effect is not consistent with the actual situation due to the complex structure of the three-dimensional models is solved. The three-dimensional model with a complex structure can be a concave body model with uneven appearance; the structurally simple three-dimensional model may be a non-concave model that is not concave in appearance. That is, in some embodiments, when obtaining the first camera distance of the three-dimensional model of the target in the virtual scene relative to the plane where the virtual camera is located, the following process may be specifically included:
obtaining the main body shape of the target three-dimensional model;
decomposing the target three-dimensional model into a plurality of sub three-dimensional models according to the main body shape, wherein the main body shape of each sub three-dimensional model is a non-concave body;
and respectively obtaining the distances of the plurality of sub three-dimensional models relative to the plane where the virtual camera is located to obtain a first camera distance.
Specifically, when the shape of the main body of the target three-dimensional model is obtained, small decorations, small objects and the like which have no shielding effect on the model can be ignored. Then, the target three-dimensional model is decomposed to different degrees according to the complexity of the shape of the main body. For example, when it is recognized that the main body shape is a concave body, the target three-dimensional model may be decomposed into a plurality of sub three-dimensional models whose main body shapes are non-concave bodies, and a splitting example may refer to fig. 5 (the left side is a concave body, and the right side is a non-concave body after splitting). And then, respectively acquiring the distance of each sub three-dimensional model relative to the plane where the virtual camera is located by utilizing the camera distance acquisition mode to obtain a first camera distance, so that a picture can be rendered based on the position relation between each sub three-dimensional model and the two-dimensional model, and the picture display effect is further improved. In order to save system resources, when the shape of the main body is recognized to be a convex body (such as a sphere and a cuboid), model decomposition is not needed.
In some embodiments, the first camera distance comprises: and the sub-camera distance of each sub-three-dimensional model relative to the plane of the virtual camera. When the front-back position relationship between the target three-dimensional model and the two-dimensional model is determined according to the first camera distance and the second camera distance, the front-back position relationship between each sub three-dimensional model and the two-dimensional model may be determined according to a plurality of sub camera distances and the second camera distance.
It can be known that, in the image rendering method provided in the embodiment of the present application, a first camera distance of the target three-dimensional model relative to the plane where the virtual camera is located and a second camera distance of the two-dimensional model relative to the plane where the virtual camera is located in the virtual scene are respectively obtained, and a front-back position relationship between the target three-dimensional model and the two-dimensional model is determined according to the first camera distance and the second camera distance. And determining the areas of the target three-dimensional model and the two-dimensional model which need to be drawn at least based on the front-back position relation, and performing picture rendering on the areas which need to be drawn. The model is regarded as a whole in the scheme, the front-back position relation between the objects is judged through the distance between the model and the virtual camera plane, so that the distances between all points on the model and the camera are kept consistent, the model is ensured to be positioned in front of or behind the two-dimensional model at the same time, the problem of interpenetration between the objects is avoided, and the picture display effect is improved.
The above-mentioned image rendering method will be further described in detail in the embodiments of the present application, taking the two-dimensional model as a two-dimensional paper figure and the three-dimensional model as a seat model as examples.
Specifically, a sequence number needs to be allocated to each two-dimensional character in the virtual scene, and since the Stencil Buffer generally has 8 bits, if the number of characters is less than 8, the sequence numbers of 0-7 can be allocated in sequence; otherwise, the human beings can be clustered, and divided into 8 classes, and then the serial numbers of 0-7 are distributed according to the classes.
Since the 2.5D view angle is used, it is simple to determine the anteroposterior relationship between the 2D character and the 3D model, and therefore, the positions of the two can be selected and compared by calculating the distance in the camera direction. The camera distance is used instead of the depth of the prior art because the depth information is pixel-level and the depth is different at different places on the same object, which causes one part of the object to be in front of the character and the other part to be behind the character, resulting in the interpenetration effect. And the information that the camera distance is consistent on the object can ensure that the object is in front of or behind the person at the same time.
In practical application, the center point of the three-dimensional model can be selected to calculate the distance between the three-dimensional model and the plane where the virtual camera is located, so that the camera distances between other points on the three-dimensional model and the plane where the virtual camera is located are consistent with the camera distance between the center point and the plane where the virtual camera is located.
It should be noted that. For some special models (such as carpet and floor) which do not cause the blocking of people, the position relation of the model does not need to be considered.
Because the Stencil Buffer generally has 8 bits and can respectively correspond to 8 personal article serial numbers, for each three-dimensional model, one bit of the three-dimensional model is set to be 1 to represent that a two-dimensional paper sheet person with a corresponding serial number is in front of the three-dimensional model, and is set to be 0 to represent that a two-dimensional paper sheet person with a corresponding serial number is behind the three-dimensional model; for each two-dimensional sheet man, the corresponding bit is set to 1.
During model rendering, specifically, a tencil value of the model is written into a tencil Buffer, so that the effect of controlling the display of the two-dimensional model is achieved. Assume for three-dimensional model a that two-dimensional sheet people with numbers 1, 3, and 6 are located at its back, and the rest are located at its front. Then, the tencel value of the three-dimensional model a: 0b 00100101. Where 0b represents the prefix of the binary number, the ontology is 00100101, the tencel operation is set to replace, and the value is written into the tencel Buffer template cache when drawing the picture.
Before rendering the character, the current tencil value is checked. If the corresponding position is 1, the position is blocked, and drawing is not performed, otherwise, the control of the two-dimensional model is drawn. Assuming that the serial number is 1 for the person B, the mask information step mask of B is 0B00000010, and the operation of the stencil buffer test step is not equal, that is, the and operation is performed on the step value of the current pixel and the mask information step mask during drawing. If the value is 1, drawing is not carried out so as to realize the shielding of the three-dimensional model on the two-dimensional paper sheet.
In practical applications, when a three-dimensional model is taken as an example of a seat presenting a concave body, when a two-dimensional paper sheet person sits on the seat, the two-dimensional paper sheet person will block in front due to the armrest of the seat, and therefore an effect inconsistent with the actual situation is generated. This is because the small person is closer to the camera than the seat, so the system determines that the seat is positioned behind the two-dimensional paper sheet person, thus causing the seat as a whole to be obscured by the two-dimensional paper sheet person.
In order to make the armrest part block in front of the two-dimensional paper people, the seat model needs to be disassembled, and the base and the armrest are separated. Specifically, when the model is split, the main body shape of the three-dimensional model may be obtained first (ignoring small decorations and small objects without occlusion), then the shape with the recess may be split into shapes without the recess (specifically, refer to a method of convex splitting a concave polygon), and finally a plurality of convex polyhedrons of the three-dimensional model may be obtained. For example, referring to fig. 6, the concave body seat is divided into three rectangular parallelepipeds, an armrest X1, a base X2, and an armrest X3.
And finally splitting the original model according to the split position to obtain a final result. When a small person sits in the chair, the base is adjusted to the back of the small person and the armrests are adjusted to the front of the small person, and then drawing is performed according to the previous method. The scheme can solve the problems of seats with armrests, galleries with railings and the like, and the characters have more substituted feeling.
The model is regarded as a whole in the scheme, the front-back position relation between the objects is judged through the distance between the model and the virtual camera plane, so that the distances between all points on the model and the camera are kept consistent, the model is ensured to be positioned in front of or behind the two-dimensional model at the same time, the problem of interpenetration between the objects is avoided, and the picture display effect is improved.
