This project investigated the use of the RenderMan photorealistic rendering system as a direct volume renderer. Commercial direct volume rendering solutions are rare, and, where they exist, are quite costly. These methods, and others, are well-developed, but generally exist only in specialized research environments where they must be internally developed, maintained, and documented. The direct volume rendering methods have all approached the problem with the idea that a quality rendering is more important than reducing the time necessary to get it. Direct volume rendering has included image-based approaches such as ray tracing, and object-based approaches such as splatting. ![]() By rendering the entire volume directly, the user can manipulate the transfer function to reveal key details in the volume dataset. Keywords: Computer Graphics, Scientific Visualization, Volume Rendering, Volumetric Imaging, Rendering Algorithms Introduction Direct volume rendering us a core tool in a visualizer s toolkit. This paper shows how to use RenderMan in this way and shows several example images. The fact that it is a commercial package that is well-supported and well-documented is an added bonus. Many of the same qualities that make it excellent for entertainment rendering also make it excellent for displaying and animating volumes. What most people don t know is that it can also be used quite effectively as a direct volume renderer. 1 Using Photorealistic RenderMan for High-Quality Direct Volume Rendering Cyrus Jam Mike Bailey San Diego Supercomputer Center University of California San Diego Abstract With the success of Pixar s recent feature films, everyone knows RenderMan to be the leading photorealistic renderer for animation and entertainment.
