- Abstract
- The accuracy of physically based lighting simulation and realistic rendering are considered in the paper. The analysis of global illumination simulation errors (discretization and stochastic ones) is presented. The quality of rendering is determined mainly by stochastic error. The stochastic error is analyzed for the task of global illumination simulation. Also the issue of prediction of calculation time necessary to obtain requested simulation accuracy is discussed and practical approach to solve the issue is suggested. The prediction mechanism with rich user interface and criteria for simulation process termination are presented.
