This paper describes improvements to view independent rendering (VIR) that make it much more useful for multiview effects. Improved VIR's (iVIR's) soft shadows are nearly identical in quality to VIR's and produced with comparable speed (several times faster than multipass rendering), even when using a simpler bufferless implementation that does not risk overflow. iVIR's omnidirectional shadow results are still better, often nearly twice as fast as VIR's, even when bufferless. Most impressively, iVIR enables complex environment mapping in real time, producing high-quality reflections up to an order of magnitude faster than VIR, and 2-4 times faster than multipass rendering.
