NCI GPU Ray Casting (Multi-Volume) ■ Note: this is a newly added mode that should be considered experimental. ■ No hardware restrictions on this method. ■ No z-buffer compositing with polygon models. NCI GPU Ray Casting ■ This is a GLSL-based ray caster with several experimental mapping techniques. GL 3 D Texture Mapping ■ Uses texture mapping approach to volume rendering ■ compared to the two render methods above, it has slightly lower performance and slightly coarser appearance.
■ This is currently working on Linux and Win 32, but not on Mac (bug in the Open. ■ Allows z-buffer compositing with non-transparent polygon models only. VTK GPU Ray Casting ■ Uses GPU accelerated ray caster. ■ Allows zbuffer compositing with texture map cross sections and non-transparent triangulated surface model. ■ Uses level-of-detail approach where low resolution is rendered while moving, and high resolution is rendered once motion ceases.
