Wepropose an architectural approach to global illumination. The proposedrendering architecture Vision is derived from a model of the physicalrendering process, which is subsequently mapped onto an object-orientedhierarchy of classes. This design is powerful and flexible enough tosupport and exploit a large body of existing illumination algorithms forthe simulation of various aspects of the underlying physical model.Additionally, the Vision architecture offers a platform for developingnew algorithms and for combining them to create new rendering solutions.We discuss both abstract design as well as implementation issues. Inparticular, we give a detailed description of the global lightingsubsystem and show how algorithms for path tracing, bidirectionalestimators, irradiance caching, hierarchical radiosity, waveletradiosity, and wavelet radiance have been implemented withinVision 收起
