Volume Visualization tool “Voreen” has just dropped version 4.3 with some impressive new features, including a new NVidia-only OpenGL4.3-based mode for polyhedral geometries.
Voreen 4.3 adds two new raycasters: An octree-based out-of-core renderer implemented in OpenCL (sample workspace: raycasting-largedata-cl.vws), and a multi-volume raycaster implemented in OpenGL 4.3 (currently only on NVIDIA) that supports polyhedral proxy-geometries as well as integration of semi-transparent geometries (sample workspace: raycasting-multivolumegeometry.vws).
