Combining Higher-Order Wavelets and Discontinuity Meshing: a Compact Representation for Radiosity
Rendering Techniques 2004 (Eurographics Symposium on Rendering) - jun 2004
The radiosity method is used for global illumination simulation in
diffuse scenes, or as an intermediate step in other
methods. Radiosity computations using Higher-Order wavelets achieve
a compact representation of the illumination on many parts of the
scene, but are more expensive near discontinuities, such as shadow
boundaries. Other methods use a mesh, based on the set of
discontinuities of the illumination function. The complexity of this
set of discontinuities has so far proven prohibitive for large
scenes, mostly because of the difficulty to robustly manage a
geometrically complex set of triangles. In this paper, we present a
method for computing radiosity that uses higher-order wavelet
functions as a basis, and introduces discontinuities only when they
simplify the resulting mesh. The result is displayed directly,
without post-processing.
