Rendering with Handcrafted Shading Models
Abstract: This article proposes a simple technique called normal distribution function (NDF) shading. It allows an artist to handcraft shading models, with the shape and color of highlights simply stored in bitmaps. The technique uses per-pixel shading, and can also be used in conjunction with bump mapping. Anisotropic shading models can also be created.
Operations for Hardware-Accelerated Procedural Texture Animation
Abstract: This article covers a few fundamental operations for generating procedural animations, and puts these to use in specific examples that simulate fire, smoke, water, or perform image processing. With today's consumer hardware, we can even run complex cellular automata programs entirely within the rendering of a 3D accelerator and put the resulting animations to use in various effects.

Abstract:
The Blobs Go Marching Two by Two
Abstract: The challenge of accurately modelling organic shapes and the they way they slop, splash, waddle and plop has caused many game artists to crumple under the pressure of recreating such phenomena. Jeff Lander shows how to use meta-goop to create and manipulate organic objects.
Devil in the Blue Faceted Dress: Real Time Cloth Animation
Abstract: Cloth animation is tricky, and even in the world of high-end computer graphics, it’s difficult to get right. Jeff Lander wanted to create realistic cloth in his environments and on his characters, so with his hardware accelerated graphics rasterization freeing enough processor power necessary to make it possible, he set set about creating a real-time cloth simulation.
