I will discuss software and hardware versions of hierarchical image-based rendering of trees, done by reprojecting raster images of tree parts for new orientations, lighting conditions, and viewpoints. I will also discuss two algorithms for illumination under trees, one for shadow penumbras, and one for plane-parallel radiance transport, which is an approximation to radiosity. All topics will be illustrated by video animation.

Snacks will be provided.
