Real-time lighting drawing method under virtual stage environment

Abstract

The invention relates to a real-time illumination plotting method under virtual stage environment, mainly comprising: combining Deferred shading technique and clustering method to do optimization; using 3D texture to organize medium attribute information; clustering a plurality of light sources into a virtual light source; real-timely plotting the participating media under the illumination of a plurality of stage light sources. The invention combines shadow map, shadow volume and ray marching techniques and the like, to provide a method for real-time plotting indoor scene object shadows. Tests prove that the real-time illumination plotting method can actually simulate complex illumination under virtual stage environment, and has the advantages of high real-time property.

Description

technical field [0001] The invention relates to a method for real-time lighting rendering in a virtual stage environment. Background technique [0002] In the virtual environment system, authenticity and real-time performance are two major challenges in constructing virtual environment. Authenticity emphasizes whether the system can build a realistic natural environment, so that users can ignore the computer system and achieve the feeling of being in the natural environment. Real-time performance emphasizes whether the system can interact with users randomly in real time, so as to better serve various applications. [0003] The following briefly introduces some domestic and foreign experts' research status on the shadow rendering of participating media and indoor environment volumes under the illumination of multiple light sources on the virtual stage in recent years. [0004] The transmission of light in the participating medium is mainly affected by the following three p...
