Fast Multi-Layer Fog

The standard uniform-density fog model is extended to fog that varies as a function of height. The computation is still performed in constant time, independent of the complexity of the density function.

A Model for Anisotropic Reflections in Open GL

A novel approach for simulating anisotropic reflections on OpenGL-based hardware in real time. Rendering of anisotropic surfaces with one light source is as expensive as traditional texturing and lighting.

Quadratic Interpolation for Near-Phong Quality Shading

Rendering hardware can easily compute coefficients for a second-order shading functions. This is more efficient than per-pixel Phong shading or Gouraud shading with triangle subdivision at equivalent quality.

Editing 3D Objects without 3D Geometry

Given a single-source image, this system can perform 3D manipulations directly onto objects in the image without explicitly recovering the underlying 3D geometry.
