With the development and popularity of game entertainment devices, players have increasingly demanding requirements for realism and immersion in game scenes. For example, the cloud model is rendered in a VR game scene to create an immersive sensation for the player.
At present, under the condition of rendering a cloud model in a VR game, the adopted technical scheme includes two types: the first technical solution performs texture volume rendering processing on the cloud model by using a ray stepping + NOISE technique (RAY MARCHING + NOISE), but the technical solution generates high consumption. The second technical scheme comprises the following steps: firstly, creating a plurality of patch particles facing a camera, and then combining texture maps corresponding to cloud models in a game scene with the patch particles to obtain rendered cloud models. However, in the case where the player rotates the angle of view left and right, the patch facing the camera may generate a rotating effect in a direction perpendicular to the angle of view, reducing the reality of the cloud model, and causing a problem that the cloud model is not voluminous.
To address this problem, the present disclosure proposes a virtual object processing method.
It should be noted that, in the exemplary embodiment of the present disclosure, the virtual object processing method described below may be generally implemented by a server, that is, the steps of the virtual object processing method may be executed by the 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 mobile phone, a tablet, a personal computer, etc.), that is, the respective steps of the virtual object processing method may be executed 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 drawings and examples.
Fig. 1 schematically shows a flowchart of a virtual object processing method of an exemplary embodiment of the present disclosure. In the following description, a server is used as an execution subject. Referring to fig. 1, the virtual object processing method may specifically include the steps of:
s102, obtaining a first virtual object, wherein the first virtual object comprises a plurality of mutually crossed 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, flying dust, etc. in a virtual scene, and a model of the first virtual object may be used to simulate a virtual model of cloud fog.
The number of patches included in the first virtual object may be, but is not limited to, derived from the size of the three-dimensional model and a 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 acquires the first virtual object, according to an exemplary embodiment of the present disclosure, the server may first acquire a map corresponding to the first virtual object; then, constructing a three-dimensional model by utilizing a plurality of mutually crossed surface patches; subsequently, 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 cloud map 201, then constructs a three-dimensional model 203 by using two patch crosses, and then combines the cloud map 201 and the three-dimensional model 203 to determine a virtual object: cloud 205.
And S104, determining the normal direction of each patch.
In an exemplary embodiment of the present disclosure, a normal of a patch may refer to a straight line passing through a center position of the patch and perpendicular to the patch, and a normal direction may be a direction outward of the perpendicular patch.
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 of the patch, and a direction of the straight line perpendicular to the patch and outward may be determined as a normal direction.
The server may use a direction passing through the center position of the patch and vertically facing the patch as the normal direction.
And S106, determining the reference normal direction of the scene where the first virtual object is located.
The scene in which the first virtual object is located is a three-dimensional virtual scene, and may be a virtual game scene or a virtual animation scene, for example. The scene in which the first virtual object can be constructed can be taken as the scene protected by the present disclosure.
The reference normal of the scene may be any line of sight for viewing the surroundings outside the first virtual object, and the reference normal direction may be a direction towards the first virtual object along any line of sight. The reference normal direction may also be referred to as a viewing angle direction. The reference normal direction may be the same as the normal direction of the patch or opposite to the normal direction of the patch.
And S108, respectively calculating an included angle between the normal direction of each surface patch and the reference normal direction, and adjusting the transparency of the corresponding surface patch according to the calculated included angle.
In an exemplary embodiment of the present disclosure, the transparency of the patch may refer to the degree to which the patch is visible. When the transparency of the patch is 1, it can indicate that the patch is completely visible; when the transparency of the patch is 0, it may indicate that the patch is completely invisible; when the transparency of the patch is a number between 0 and 1, the transparency of the patch can be expressed.
After the normal direction of each patch and the reference normal direction of the scene where the first virtual object is located are determined, the server may first 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, and then calculate an included angle between the normal direction of each patch and the reference normal direction after the normalization processing, respectively.
It should be noted that the value of the included angle between the normal direction of each patch after the normalization process and the reference normal direction 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 and flaky object feeling between objects in a rendering scene are solved, the volume feeling of the virtual object is improved, and the rendering effect is more realistic.
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 execution effect after a virtual object processing method is executed in a virtual reality game.
And after the server respectively calculates the included angle between the normal direction of each surface patch after normalization processing and the reference normal direction, comparing the calculated included angle 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.
The transparency of the patch and the included angle are in a negative correlation relationship, namely, the larger the angle is, the lower the transparency of the patch is.
Referring to fig. 4, the left side of the arrow indicates that the angle between the normal direction of a patch in the virtual object and the reference normal direction is 90, the transparency is low, and the sheet-like effect is generated. The right side of the arrow indicates that the transparency of each patch of the virtual object becomes high after the angle is adjusted, and the virtual object has no rendering effect of flaky feeling.
The transparency of the corresponding patch is adjusted by the calculated included angle, and the included angle threshold value is set, so that the included angle range is more accurate, the transparency adjusting process of the first virtual object is further simpler, and the resource consumption is reduced.
According to the exemplary embodiment of the present disclosure, the server may also perform a dot product operation on the normal direction of each normalized patch 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 a nonlinear fitting process on the calculated included angle through a preset power function to determine the 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 center coordinates of the first virtual object; and if the distance belongs to 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 patches included in the first virtual object and intersecting with each other. The reference position coordinates of the scene in which the first virtual object is located may be position coordinates for observing the first virtual object. The preset distance range may be a distance determined according to a position coordinate corresponding to a case where the transparency of the first virtual object is completely visible and a position coordinate corresponding to a case where the transparency of the first virtual object is completely invisible.
The server may compare whether a 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 the 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, 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 to be understood by workers.
According to an exemplary embodiment of the present disclosure, the first virtual object is located in a scene including 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, or the like in the virtual game scene. The first depth difference value may refer to a portion where a pixel depth value of the first virtual object is greater than a pixel depth value of the second virtual object. The overlap region may refer to a region where 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 the server determines the first depth difference value, the server may add the first depth difference value to the pixel depth value of the second virtual object to obtain an 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 disclosure, if there is an overlapping area between the first virtual object and the second virtual object, the server may determine a second depth difference value of the first virtual object and the second virtual object in the overlapping area; 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.
Here, the second depth difference value may be a pixel depth value of a region where the first virtual object is displayed in the second virtual object model, that is, may be a pixel depth value of an overlapping region between the first virtual object and the second virtual object.
The pixel depth value of the second virtual object is adjusted, so that the second virtual object covers the overlapping area, the problem that the first virtual object and the second virtual object are obviously interspersed is reduced, and the rendering effect of the virtual scene is improved.
Fig. 5 illustrates the effect of two virtual objects before and after the interleaving fusion rendering in the virtual scene, where the first virtual object 502 and the second virtual object 504 are interleaved with each other and have 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 exhibits a pronounced interspersed rendering effect and has a flaky feel before the pixel depth value of the second virtual object 504 is adjusted. 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 interleaving, and improves the interleaving fusion rendering effect of the two virtual objects in the virtual scene.
According to an exemplary embodiment of the present disclosure, the first virtual object includes surface color features of the first virtual object, and the server may first acquire illumination information; then, determining the illumination influence intensity of the first virtual object; subsequently, the surface color feature of the first virtual object is adjusted 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 color feature overlaid on the surface of the first virtual object, and the illumination information may be, for example, yellow-colored illumination, and may be, for example, red-colored illumination.
The light influencing intensity can be represented by a value from 0 to 1. 0 may indicate that the surface color feature of the first virtual object is not affected by illumination; 1 may indicate that the surface color feature of the first virtual object is affected by illumination and is intense; a value between 0-1 may represent an intensity value at which the surface color feature of the first virtual object is affected by the illumination. In addition, 1 may also indicate that the surface color feature of the first virtual object is not affected by illumination; 0 may also indicate that the surface color feature of the first virtual object is affected by illumination and is intense.
It should be noted that although the various steps of the methods of the present disclosure are depicted in the drawings in a particular order, this does not require or imply that these steps must be performed in this particular order, or that all of the depicted steps must be performed, to achieve desirable results. Additionally or alternatively, certain steps may be omitted, multiple steps combined into one step execution, and/or one step broken down into multiple step executions, etc.
Further, in an exemplary embodiment of the present disclosure, a virtual object processing apparatus is also provided.
