Abstract
Functionally defined objects for realistic scenes are proposed. Physically correct visualization of three-dimensional objects based on perturbation functions is described. That is, the rendering of materials takes into account the laws of physics. Physically correct reflection models are necessary to obtain photorealistic images. The roughness, micro relief, and surface gloss indicate how smooth or rough the surface of the material is. This paper shows the effects of diffraction taking into account the surface roughness. Subsurface light transport is also considered, which is modeled using bidirectional surface scattering.
