Image-Based Tree Rendering

Aleks Jakulin sent along the following information about a hardware-based method for rendering "dozens, even hundreds" of solid trees in real-time:

" A single realistic mesh of a tree contains enough polygons to bog down any graphics accelerator. What meshes cannot images often can. Image-based rendering is based on representing complex geometry with a set of images. A robust hardware-based approach to IBR is slicing-and-blending, and with it it's possible to render dozens, even hundreds of solid 3D trees in real-time. Because antialiasing is a byproduct of hardware-based IBR, the S&B trees usually look better than the mesh-based originals.

A Windows+OpenGL demonstration executable and a detailed description of the method are available at
