Progressive Previewing of Ray-Traced Images Using Image-Plane Discontinuity Meshing,pdates a constrained Delaunay triangulation of the image plane. The points in the triangulation correspond to all of the image samples that have been computed by the ray tracer, and the constraint edges correspond to various important discontinuity edges in the image. The triangulation is displayed

An adaptive representation of spectral data for reflectance computations,are projected on a set of hierarchical basis functions called scaling functions leading to a representation by means of binary trees. An adaptive algorithm is proposed in which refinement and merge steps managed by an estimation of the error made in the . color space allows to control the representa

Filtered Local Shading in the Wavelet Domain, final shading. This operation should filter all light over the incident hemisphere through the BRDF to generate an accurate image. This can be done analytically for simple BRDFs, such as Lambertian or Phong-like BRDFs, but becomes more difficult in the presence of a general BRDF..This paper present

An Empirical Comparison of Progressive and Wavelet Radiosity, at several parameter settings, and results were examined in terms of their error, speed, and memory consumption. We did not compare more advanced variations such as clustering or discontinuity meshing. Our results show that progressive radiosity with substructuring works fairly well for all scenes.
