Grouping of Patches in Progressive Radiosity
نویسنده
چکیده
The radiosity method can be improved by (adaptively) grouping small neighboring patches into groups. Computations normally done for separate patches are now applied to these groups. Groups receive energy from the environment, and can shoot energy into the environment. The radiosities of the patches in the group are derived from the energy the group receives. Grouping small patches reduces the number of form factor computations, reduces aliasing effects, and improves the convergence in progressive radiosity. This paper presents methods for grouping small patches in progressive radiosity algorithms with ray tracing based form factor computations.

A progressive radiosity algorithm based on piecewise polynomial intensity distribution
A progressive radiosity algorithm based on piecewise polynomial intensity distribution is presented in the paper. Unlike the conventional radiosity method, radiosity across each patch is assumed to vary in a polynomial distribution. A generalized radiosity equation for scenes with nondiffuse surfaces is then set up and solved by adopting progressive refinement technique. To improve the efficien...
متن کاملFast Radiosity Solutions for Environments with High Average Reflectance
In radiosity algorithms the average radiance of Lambertian patches is approximated by solving a linear system with unknowns. When is small (i.e. fewer than thousands of patches), general matrix methods like Gauss-Siedel can be used where the explicit matrix can be pre-computed and stored [5]. When is large, progressive techniques are used where the matrix rows or elements are recomputed as need...
متن کاملClustering-Based Hierarchical Radiosity for Dynamic Environments
This paper extends hierarchical radiosity and clustering techniques to dynamic environments, in which dynamic manipulations, such as repositioning an object and changing surface attributes, are repeatedly applied. The cluster techniques can be effective in reducing the computational complexity of both initial linking creation and link updating of dynamic manipulations. When the object is reposi...
متن کاملA Parallel Method For Progressive Radiosity
The quality of synthetic images depends, rst, on the quality of the modeling of the three-dimensional scene to visualize. More numerous are the speciied geometrical and optical details, more realistic is the result image. Unfortunately, such scene descriptions need a big amount of memory, and then they need a long time of computation. In order to deal with these restrictions, we propose a paral...
متن کاملParallel Progressive Radiosity with Adaptive Meshing
Progressive radiosity is widely used for realistic image synthesis in computer graphics applications. High-quality image generation usually requires radiosity with adaptive patch refinement to account for global illumination effects from irregular objects whose proximity varies in a 3D space. Parallelizing such an algorithm is difficult since computation cost for each object varies from one ite...
