Volume rendering

Volume rendering is a technique for directly displaying a sampled 3D scalar field without first fitting geometric primitives to the samples. We are working on developing efficient and accurate algorithms for displaying this sort of data. Our goal is photorealistic real-time volume rendering of usefully large scientific, engineering, and medical datasets on affordable noncustom hardware. We have also worked on techniques for morphing volumes.

The project represented by this web page has been inactive for several years. However, there are two new efforts related to volume rendering that are currently going on in our laboratory. The first is a project to incorporate volume rendering into the Stanford Real-Time Programmable Shading Language and to build a parallelized volume renderer for our 32-processor PC cluster. This project is under the direction of Pat Hanrahan. The second is a project to create a book of volume renderings, tentatively called Volumegraphica. If you're a Stanford student interested in working on this project, talk to Marc Levoy.
