Realism here means to generate images on a computer which are indistinguishable from real photos.
This realism is possible through the use of local and global illumination methods. The basis for a physically correct calculation of the illumination depends on the accuracy of the scene description. This means both the geometry as well as the description of the surfaces and light sources. Aim of this project is to find an accurate and efficient way to measure and define material or surface properies for generating realistic images. Applications are in the fields of architecture, lighting design and optimization, visual shape and fine arts.
