    Intended Audience

    Computers Graphics practitioners of all stripes: from Technical Directors, to Pipeline Engineers, Shading Artists, Lighting Artists, Render Wranglers, and Software Developers, should find this course both interesting and useful.


    While the topic is intuitively relevant to computer graphics, we do use some jargon the audience should be familiar with, such as LOD, BRDF, “in-core” vs “out of core”, CPU/GPU, UV Parameterization, Shader, Displacement, Ray Tracing, and Rasterization. Those familiar with shading/rendering will likely keep up best.
