Very impressive! Curious what the frame rate would be like for stereoscopic rendering of the same scene on the same hardware. Are there optimizations to be had past the halfway mark?
Definitely. One of the time-consuming parts of rendering is sorting the gaussians by distance to the camera, which for two nearby cameras could be optimized. This also goes for adjacent frames - assuming smooth motion im pretty sure there is some speedup to be had by assuming the previous sort will be close to correct rather than starting from scratch each frame.
