With the development and popularization of game entertainment devices, players have increasingly demanded reality and immersion of game scenes. For example, cloud models are rendered in VR game scenes to create immersion for players.
At present, under the condition of rendering a cloud model in a VR game, the adopted technical scheme comprises two types: the first technical solution adopts a ray stepping+noise technology (RAY MARCHING +noise) to perform texture volume rendering processing on the cloud model, but the technical solution can generate high consumption. The second technical scheme comprises the following steps: firstly, creating a plurality of facing camera surface patch particles, and then combining texture maps corresponding to cloud models in game scenes with the surface patch particles to obtain rendered cloud models. However, when the player rotates the view angle in the left-right direction, the face sheet facing the camera has a rotation effect in the direction perpendicular to the view angle, which reduces the sense of realism of the cloud model and causes a problem that the cloud model has no sense of volume.
In response to the problem, the present disclosure proposes a virtual object processing method.
It should be noted that, in the exemplary embodiments of the present disclosure, the virtual object processing method described below may be generally implemented by a server, that is, each step of the virtual object processing method may be performed by a server, in which case the virtual object processing apparatus may be configured in the server.
In addition, the virtual object processing method may be implemented by a terminal device (e.g., a cellular phone, a tablet, a personal computer, etc.), that is, the respective steps of the virtual object processing method may be performed by the terminal device, in which case the virtual object processing apparatus may be configured in the terminal device.
Hereinafter, each step of the virtual object processing method in the present exemplary embodiment will be described in more detail with reference to the accompanying drawings and examples.
Fig. 1 schematically illustrates a flowchart of a virtual object processing method of an exemplary embodiment of the present disclosure. In the following description, an example is described in which a server is an execution subject. Referring to fig. 1, the virtual object processing method may specifically include the steps of:
S102, acquiring a first virtual object, wherein the first virtual object comprises a plurality of intersecting patches.
In an exemplary embodiment of the present disclosure, the first virtual object may be, but is not limited to, various objects simulating real clouds, fog, dust, etc. in a virtual scene, and a model of the first virtual object may be used to simulate a virtual model of the cloud fog.
The number of patches included in the first virtual object may be, but is not limited to, obtained according to the size of the three-dimensional model and the preset consumption number; the number of patches may also be adjusted during construction of the three-dimensional model according to the rendering effect of the game scene.
Before the server obtains the first virtual object, according to an exemplary embodiment of the present disclosure, the server may first obtain a map corresponding to the first virtual object; then, constructing a three-dimensional model by using a plurality of mutually intersected patches; then, a first virtual object is determined based on the map and the three-dimensional model.
The map may be a picture containing the object that the first virtual object needs to simulate.
Taking fig. 2 as an example, the server first obtains a map 201 of the cloud, then constructs a three-dimensional model 203 using two crisscross patches, and then combines the map 201 of the cloud and the three-dimensional model 203 to determine a virtual object: cloud 205.
S104, determining the normal direction of each patch.
In an exemplary embodiment of the present disclosure, the normal line of the panel may refer to a straight line passing through the center position of the panel and perpendicular to the panel, and the normal line direction may be the direction in which the panel is outward.
After the server acquires the first virtual object, a straight line passing through the center position of the patch and perpendicular to the patch may be determined as a normal line of the patch, and an outward direction of the straight line vertical patch may be determined as a normal line direction.
The server may set a direction passing through the center of the patch and oriented vertically to the patch as a normal direction.
S106, determining a reference normal direction of a scene where the first virtual object is located.
The scene where the first virtual object is located is a three-dimensional virtual scene, for example, may be a virtual game scene or a virtual animation scene. A scenario in which the first virtual object may be constructed may be regarded as a scenario protected by the present disclosure.
The reference normal line of the scene may be any line of sight for observing the outer periphery of the first virtual object, and the reference normal line direction may be a direction along any line of sight toward the first virtual object. The reference normal direction may also be referred to as the viewing angle direction. The reference normal direction may be the same as or opposite to the normal direction of the patch.
S108, respectively calculating the included angles between the normal direction of each surface piece and the reference normal direction, and adjusting the transparency of the corresponding surface piece according to the calculated included angles.
In exemplary embodiments of the present disclosure, the transparency of a dough sheet may refer to the degree to which the dough sheet is visible. When the transparency of the dough sheet is 1, it may indicate that the dough sheet is completely visible; when the transparency of the dough sheet is 0, it may indicate that the dough sheet is completely invisible; when the transparency of the dough sheet is a number between 0 and 1, the transparency degree of the dough sheet can be expressed.
After determining the normal direction of each patch and the reference normal direction of the scene where the first virtual object is located, the server may perform normalization processing on the normal direction of each patch and the reference normal direction of the scene where the first virtual object is located first, and then calculate the included angle between the normal direction of each patch and the reference normal direction after the normalization processing.
It should be noted that, the value of the included angle between the normal direction of each of the patches and the reference normal direction after normalization processing may be any value between 0 and 1.
According to the method and the device, the included angle between the normal direction of each surface patch and the reference normal direction is calculated, and the transparency of the corresponding surface patch is adjusted according to the calculated included angle, so that the problems of obvious interpenetration between objects and flaky sensation of the objects in a rendering scene are avoided, the volume sensation of the virtual object is improved, and the rendering effect is enabled to have more realism.
In an exemplary embodiment of the present disclosure, the virtual object processing method may be applied to a virtual reality game. Fig. 3 illustrates a game running effect after running the virtual object processing method in the virtual reality game.
And after calculating the included angles between the normal direction of each surface piece and the reference normal direction after normalization processing, the server compares the calculated included angles with an included angle threshold value. And if the calculated included angle is larger than the included angle threshold value, adjusting the transparency of the corresponding dough sheet according to the calculated included angle.
Wherein, the transparency of the dough sheet and the included angle form a negative correlation, namely, the larger the angle is, the lower the transparency of the dough sheet is.
Referring to fig. 4, the left side of the arrow indicates that the angle between the normal direction of a panel in the virtual object and the reference normal direction is 90, the transparency is low, and the flaky effect is generated. The right side of the arrow shows the rendering effect that the transparency of each patch of the virtual object becomes high after the angle is adjusted, and the virtual object has no flaky feel.
According to the method and the device, the calculated included angle is used for adjusting the transparency of the corresponding dough piece, and the included angle threshold value is set, so that the range of the included angle is more accurate, the transparency adjusting process of the first virtual object is further simpler, and the resource consumption is reduced.
According to an exemplary embodiment of the disclosure, the server may also perform dot product operation on the normal direction of each patch after normalization processing and the reference normal direction to obtain an included angle between the normal direction of each patch and the reference normal direction, and then perform nonlinear fitting processing on the calculated included angle through a preset power function to determine transparency of the patch corresponding to the calculated included angle.
According to another exemplary embodiment of the present disclosure, the server determines center coordinates of the first virtual object; determining reference position coordinates of a scene where the first virtual object is located; calculating a distance between the reference position coordinates and the center coordinates of the first virtual object; and if the distance is within the preset distance range, adjusting the transparency of the first virtual object according to the distance.
The center coordinates of the first virtual object may be center position coordinates of a plurality of intersecting patches included in the first virtual object. The reference position coordinates of the scene in which the first virtual object is located may be position coordinates for viewing the first virtual object. The preset distance range may be a distance determined according to a position coordinate corresponding to a completely visible condition of the transparency of the first virtual object and a position coordinate corresponding to a completely invisible condition of the transparency of the first virtual object.
The server may compare whether the distance between the reference position coordinate and the center coordinate of the first virtual object is within a preset distance range after calculating the distance between the reference position coordinate and the center coordinate of the first virtual object, and if the result is that the distance between the reference position coordinate and the center coordinate of the first virtual object is within the preset distance range, the server may adjust the transparency of the first virtual object according to the distance between the reference position coordinate and the center coordinate of the first virtual object.
It should be noted that, when the distance between the reference position coordinate and the center coordinate of the first virtual object falls within the preset distance range, the distance between the reference position coordinate and the center coordinate of the first virtual object has a positive correlation with the transparency of the first virtual object. For example, in a case where the distance between the reference position coordinate and the center coordinate of the first virtual object falls within a preset distance range, the smaller the distance between the reference position coordinate and the center coordinate of the first virtual object, the smaller the transparency of the first virtual object until the first virtual object is invisible. Conversely, the greater the distance between the reference position coordinates and the center coordinates of the first virtual object, the greater the transparency of the first virtual object until the first virtual object is fully visible.
According to the method and the device for adjusting the transparency of the first virtual object, the transparency of the first virtual object is adjusted according to the distance between the reference position coordinate and the center coordinate of the first virtual object within the preset distance range, so that the transparency of the first virtual object is adjusted more flexibly, and the display process of the transparency of the virtual object is facilitated for workers to understand.
According to an exemplary embodiment of the present disclosure, a scene in which a first virtual object is located includes a second virtual object, and if a pixel depth value of the second virtual object in the scene is smaller than a pixel depth value of the first virtual object, the server may determine a first depth difference value between the first virtual object and the second virtual object; and if the first virtual object and the second virtual object have an overlapping area, adjusting the pixel depth value of the second virtual object based on the first depth difference value so that the second virtual object covers the overlapping area.
The second virtual object may be, for example, a mountain, a tree, etc. in the virtual game scene. The first depth difference value may refer to a portion of the first virtual object having a pixel depth value that is greater than a pixel depth value of the second virtual object. The overlapping region may refer to a region in which the first virtual object is displayed in the second virtual object. The first depth difference value may be greater than a pixel depth value of the overlap region.
It should be noted that, the server may also increase the pixel depth value of the second virtual object to infinity so as to completely cover the overlapping area of the first virtual object and the second virtual object.
After determining the first depth difference, the server may increase the first depth difference to the pixel depth value of the second virtual object, to obtain the adjusted pixel depth value of the second virtual object, so as to completely cover the overlapping area of the first virtual object and the second virtual object.
According to an exemplary embodiment of the present disclosure, if there is an overlapping region between the first virtual object and the second virtual object, the server may determine a second depth difference value between the first virtual object and the second virtual object in the overlapping region; determining a contour line of the second virtual object in the overlapping area; and adjusting the pixel depth value of the second virtual object according to the contour line and the second depth difference value so that the second virtual object covers the overlapping area.
The second depth difference value may be a pixel depth value of an area where the first virtual object is displayed in the second virtual object model, that is, a pixel depth value of an overlapping area between the first virtual object and the second virtual object.
According to the method and the device, the pixel depth value of the second virtual object is regulated, so that the second virtual object covers the overlapping area, the obvious problem of interpenetration between the first virtual object and the second virtual object is reduced, and the rendering effect of the virtual scene is improved.
Fig. 5 illustrates the effect of the two virtual objects in the virtual scene before and after the interpenetration and fusion rendering, wherein the first virtual object 502 and the second virtual object 504 interpenetrate each other with an overlapping region therebetween.
The left side of the arrow illustrates that the overlapping area of the first virtual object 502 and the second virtual object 504 shows a distinct interpenetration rendering effect and has a flaky feel before adjusting the pixel depth value of the second virtual object 504. The right side of the arrow illustrates that after the pixel depth value of the second virtual object 504 is adjusted, the overlapping area of the first virtual object 502 and the second virtual object 504 overcomes the problem of obvious interpenetration, and improves the interpenetration fusion rendering effect of the two virtual objects in the virtual scene.
According to an exemplary embodiment of the present disclosure, a first virtual object includes a surface color feature of the first virtual object, and a server may first acquire illumination information; then, determining the illumination influence intensity of the first virtual object; and then, adjusting the surface color characteristics of the first virtual object according to the illumination information and the illumination influence intensity so as to obtain an adjusted first virtual object.
Wherein the surface color feature of the first virtual object may refer to a color feature overlaid on the surface of the first virtual object. The illumination information may refer to color information of a surface color feature overlaid on the first virtual object, and the illumination information may be, for example, illumination of a yellow color, for example, illumination of a red color.
The illumination influence intensity may be represented by a value of 0-1. 0 may indicate that the surface color features of the first virtual object are unaffected by the illumination; 1 can represent that the surface color characteristics of the first virtual object are affected by illumination and have high intensity; a value between 0 and 1 may represent an intensity value of the surface color feature of the first virtual object affected by the illumination. In addition, 1 may also indicate that the surface color characteristics of the first virtual object are not affected by the illumination; 0 may also indicate that the surface color features of the first virtual object are affected by the illumination and are intense.
It should be noted that although the steps of the methods in the present disclosure are depicted in the accompanying drawings in a particular order, this does not require or imply that the steps must be performed in that particular order, or that all illustrated steps be performed, to achieve desirable results. Additionally or alternatively, certain steps may be omitted, multiple steps combined into one step to perform, and/or one step decomposed into multiple steps to perform, etc.
Further, in an exemplary embodiment of the present disclosure, a virtual object processing apparatus is also provided.
