Advanced visualization and the cinematic 3D rendering prototype

By Eric Barnes

Thursday, December 1 | All day | PH125-ED-X | Lakeside, PH CommunityDespite continuous evolution in postprocessing techniques, most 3D visualization and planning still occur on a very basic visual level. This all-day educational event covers the basics of maximum intensity projections and volume rendering techniques, and it goes on to discuss the more visually rich world of cinematic rendering of 3D volumes.
