An Integrated Model for Direct Illumination, Subsurface Scattering, Specular Highlights and Shadow Computation
MetadataShow full item record
In this thesis, we present an integrated model to compute direct illumination, subsurface scattering, specular highlights and soft shadow effects in a single equation. Using this model, it is possible to obtain various effects in a qualitatively consistent way even with a single light. The model is tested for rendering bas-reliefs, i.e. height fields under both single light and environment illumination. The model is implemented as a web-based program using WebGL. Using our system, users can see rendered results in real time even while modifying shader parameters, because of GPU rendering and computational simplicity of our integrated model.
