Predicting reflectance functions from complex surfaces
We describe a physically-based Monte Carlo technique for approximating bidirectional reflectance distribution functions (BRDFs) for a large class of geometries by directly simulat...

Variational surface modeling
We present a new approachto interactive modeling of freeform surfaces. Instead of a fixed mesh of control points, the model presented to the user is that of an infinitely malleabl...

Measuring and modeling anisotropic reflection
A new device for measuringthe spatial reflectancedistributionsof surfaces is introduced, along with a new mathematical model of sniaorropic reflectance. The reflectance model pres...

Re-tiling polygonal surfaces
This paper presents an automatic method of creating surface models at several levels of detail from an original polygonal description of a given object. Representing models at var...

Generative modeling: a symbolic system for geometric modeling
This paper discusses a new, symbolic approach to geometric modeling called generative modeling. The approach allows specification, rendering, and analysis of a wide variety of sha...

An importance-driven radiosity algorithm
We present a new radiosi[y algorithm for efficiently computing global solutions with respect to a constrained set of views. Radiosi ties of directly visible surfaces are computed ...

Computing the antipenumbra of an area light source
We define the antiumbra and the antipenumbra of a convex area light source shining through a sequence of convex areal holes in three dimensions. The antiumbra is the volume from w...
