An experimental evaluation of computer graphics imagery

摘要: Accurate simulation of light propagation within an environment and perceptually based imaging techniques are necessary for the creation realistic images. A physical experiment that verifies reflected intensities diffuse environments was conducted. Measurements radiant energy flux densities compared with predictions using radiosity method those environments. By color science procedures results model then transformed to produce a television image. The final image compares favorably original model. indicates that, when were viewed through view camera, subjects could not distinguish between them. comparison both test presented this paper.
