Abstract
A method for visualizing multi-volume data and functionally defined surfaces using graphics processing units is proposed. The method provides visualization of a large number of volumes, a set of translucent and functionally defined objects, and complex translucent volumes, including volume intersections in constructive solid modeling. Rendering different volumes at the same time is a more complex problem than rendering a single volume because intersecting and mixing operations are required. Functionally defined surfaces are well suited for embedding external objects into volumes.
