(Eurographics Association, 1989)
This paper presents a new ray-tracing acceleration technique called Pixel Selected Ray-Tracing (PSRT). PSRT uses undersampling based on Iterative Central Point Selection(ICPS) along with checking for similarities among ...
A Model for Description and Synthesis of Heterogeneous Textures
