Clustering for glossy global illumination
David H. Salesin, Eric J. Stollnitz, Per H. Christensen, Dani Lischinski
Pages: 3-33
DOI: 10.1145/237748.237749
We present a new clustering algorithm for global illumination in complex environments. The new algorithm extends provious work on clustering for radiosity to allow for nondiffuse (glossy) reflectors. We represent clusters as points with...

Multiresolution analysis for surfaces of arbitrary topological type
Michael Lounsbery, Tony D. DeRose, Joe Warren
Pages: 34-73
DOI: 10.1145/237748.237750
Multiresolution analysis and wavelets provide useful and efficient tools for representing functions at multiple levels of detail. Wavelet representations have been used in a broad range of applications, including image compression, physical...

An efficient surface intersection algorithm based on lower-dimensional formulation
Dinesh Manocha, Shankar Krishnan
Pages: 74-106
DOI: 10.1145/237748.237751
We present an efficient algorithm to compute the intersection of algebraic and NURBS surfaces. Our approach is based on combining the marching methods with the algbraic formulation. In particular, we propose and matrix computations. We present...
