Towards Interactive Bump Mapping with Anisotropic Shift-Variant BRDFs
(The Eurographics Association, 2000)
In this paper a technique is presented that combines interactive hardware accelerated bump mapping with shift-variant anisotropic reflectance models. An evolutionary path is shown how some simpler reflectance models can ...
Algorithms for Division Free Perspective Correct Rendering
(The Eurographics Association, 2000)
Well known implementations for perspective correct rendering of planar polygons require a division per rendered pixel. Such a division is better to be avoided as it is an expensive operation in terms of silicon gates and ...
