Optical flow has it's uses but for the process of 3d rendering. We use oflow for the obvious and not so obvious. speed is obvious everyone does that.
For other use We generate an oflow to solve
Utilizing and render depth pass is great for depth blur and basic out-of-the-box fog but try world position pass (to define every pixel cooridate in 3d space) to render environmental effects like volumetric fog with ray casting or fixes to 3d renders using volume masking with data derived from the world position pass That's a huge timesaver.
From hours per frame to frames per second. cheers Jeff |
