USING IMPORTANCE RESAMPLING TO REDUCE THE MEMORY INCOHERENCE OF LIGHT SAMPLING - A simplified explanation of the abstract
This abstract first appeared for US patent application 18142868 titled 'USING IMPORTANCE RESAMPLING TO REDUCE THE MEMORY INCOHERENCE OF LIGHT SAMPLING
Simplified Explanation
- The patent application is about incorporating lighting effects into computer-generated graphics. - One embodiment of the invention involves rendering a virtual scene with multiple lights. - Before rendering a frame of graphics, a random sample of lights is taken from the set of lights in the scene. - A subset of the sampled lights is then selected to render pixels within specific portions of the frame. - The purpose of this technique is to enhance the lighting effects in computer-generated graphics. - The invention aims to improve the realism and visual quality of virtual scenes by selectively using lights. - This approach allows for more efficient rendering of lighting effects in computer-generated graphics.
Original Abstract Submitted
Devices, systems, and techniques to incorporate lighting effects into computer-generated graphics. In at least one embodiment, a virtual scene comprising a plurality of lights is rendered by randomly sampling a set of lights from among the plurality of lights prior to rendering a frame of graphics. A subset of the set of lights is selected and used to render pixels within one or more portions of the frame.
