A Low Complexity Discrete Radiosity Method
Rather than using Monte Carlo sampling techniques or patch projections to compute radiosity, it is possible to use a discretization of a scene into voxels and perform some discrete geometry calculus to quickly compute visibility information. In such a framework , the radiosity method may be as precise as a patch-based radiosity using hemicube computation for form-factors, but it lowers the over...
متن کاملA Discrete Radiosity Method
We present a completely new principle of computation of radiosity values in a 3D scene. The method is based on a voxel approximation of the objects, and all occlusion calculations involve only integer arithmetics operation. The method is proved to converge. Some experimental results are presented.
متن کاملParallelization of a Discrete Radiosity Method
In this paper we present three different parallelizations of a discrete radiosity method achieved on a cluster of workstations. This radiosity method has lower complexity when compared with most of the radiosity algorithms and is based on the discretization of surfaces into voxels and not into patches. The first two parallelizations distribute the tasks. They present good performance in time bu...
متن کاملParallelization of a Discrete Radiosity Method Using Scene Division
We present in this article a parallelization of a discrete radiosity method, based on scene division and achieved on a cluster of workstations. This method is based on discretization of surfaces into voxels and not into patches like most of the radiosity methods do. Voxels are stocked into visibility lists representing the space partition into discrete lines and allowing mutually visible neighb...
متن کاملOne Method to Reduce Complexity of Matrix Radiosity Algorithm
The given report is devoted to an original approach for reducing computational cost (memory and time) of the matrix radiosity algorithm. Such investigations are still quite actual because the algorithm requires significant amounts of memory and time. From other side it began to be applied in practice due to increasing power and memory of modern desktop computers. Recent efforts of computer grap...
