Interactive Rendering of Translucent Objects

A novel technique allows for rendering translucent objects at
interactive rates with arbitrary incident illumination. Previous
rendering techniques required up to several minutes to evaluate the
reflected radiance depending on the incident illumination on every
surface point. Precomputation of how energy impinging at one point is
distributed to all other surface points at two different resolutions
yields much faster evaluation. During rendering a local term (bottom
left) and a global term (bottom center) are combined to the final
result (bottom right). The top row shows the same back lit geometry
with two different materials.
