Three-dimensional virtual scene rendering method and device, electronic equipment and storage medium

Abstract

The embodiment of the invention relates to a rendering method and device for a three-dimensional virtual scene, electronic equipment and a storage medium, and the method comprises the steps: projecting a sight line to a target position on the surface of a to-be-colored target virtual object made of a semitransparent material in the three-dimensional virtual scene from a virtual viewpoint; the method comprises the following steps: performing light ray tracing on a sight line, and when a virtual object made of a semitransparent material in a three-dimensional virtual scene is tracked each time, starting from a collision position of the current tracking sight line on the virtual object, respectively projecting a reflection sight line and a refraction sight line along a corresponding reflection direction and a refraction direction, taking the refraction sight line as a tracking sight line to continue light ray tracking, and stopping tracking until the virtual light source is tracked; and determining a coloring result of the target position according to the surface information of each collision position generated in the ray tracing process. Therefore, the display of the semi-transparent virtual object in the virtual mirror surface can be close to the real effect in the scene of real-time ray tracing rendering of the game engine.

Description

technical field [0001] The embodiments of the present invention relate to the field of computers, and in particular to a rendering method, device, electronic equipment and storage medium for a three-dimensional virtual scene. Background technique [0002] In the computer field, ray tracing is widely used in computer games and animations, TV and DVD production, and film productions. At present, with the improvement of graphics card hardware performance and the industry's proposed DXR API application programming interface specification for ray tracing, real-time ray tracing rendering processes have been implemented in some game engines, such as the Unreal engine. [0003] However, in the scene rendered by UE4 (Unreal Engine 4) game engine for real-time ray tracing, the virtual objects (such as glasses, glass balls, etc.) of translucent materials in the virtual mirror will appear black (the effect can be found in figure 1 ), which obviously does not conform to the real physica...

[0003] However, in the scene rendered by UE4 (Unreal Engine 4) game engine for real-time ray tracing, the virtual objects (such as glasses, glass balls, etc.) of translucent materials in the virtual mirror will appear black (the effect can be found in figure 1 ), which obviously does not conform to the real physical imaging rules, resulting in a poor visual experience for users on the rendering results of translucent material virtual objects in the virtual scene
