Analysis and Implementation of Displacement Shaders
David Loh
Abstract:
In this report, the Renderman texturing/modelling method known as displacement mapping is put under the microscope. What it is, and where and how it is used is covered in varying depth. I set out primarily to learn more about Renderman, then apply my new found knowledge in the creation of a couple of my own displacement shaders. It is hoped that this paper contains sufficient material to educate those who are ignorant to the actual displacement mapping method and its relationship to Renderman. The research section of the text is either based upon, or quoted from previous research and publications, due to the sheer clarity of explanation. Other topics covered are Noise, Antialiasing and Spectral Synthesis.
