What are the limitations of recursive refraction?

May 9, 2021 ... My question is: when such overlapping geometries are intersected with a ray, how does one choose which of the two geometries should be prioritized? This paper is a continua- tion of that work in the context of ray tracing. Blinn introduced the use of density models in computer graphics in Blinn (1982), ... Computer Graphics (CS 543).
