Applications of irradiance tensors to the simulation of non-Lambertian phenomena
We present new techniques for computing illumination from non-diffuse luminaires and scattering from non-diffuse surfaces. The methods are based on new closed-form expressions d...

Illumination in diverse codimensions
This paper derives a model of diffuse and specular illumination in arbitrarily large dimensions, based on a few characteristics of material and light in 3-space. It then describes...

Tracing Ray Differentials
Antialiasing of ray traced images is typically performed by supersampling the image plane. While this type of filtering works well for many algorithms, it is much more efficient t...

Improved Specular Highlights With Adaptive Shading
Gouraud shading and Phong shading are widely used interpolation methods to render a polygon mesh of a curved surface. When an illumination equation has a specular reflection term,...

Large-Scale Modeling of Parametric Surfaces Using Spherical Harmonics
We present an approach for large-scale modeling of parametric surfaces using spherical harmonics (SHs). A standard least square fitting (LSF) method for SH expansion is not scala...
