volume renderer

volume_renderer

Volume_renderer directly renders a 3D uniform field using either the Back-to-Front (BTF) or Ray-tracing volume rendering techniques. The Ray-tracing mode is available to both OpenGL and the software renderer. The BTF renderer, which is configured as the default, is available only in the OpenGL renderer.

NOTE: This module and its rendering technique are not supported in C Tech Web Scenes (CTWS files).

The basic concept of volume rendering is quite different than anything other rendering technique in EVS. Volume_renderer converts data into a fuzzy transparent cloud where data values at each point in a 3D grid are represented by a particular color and opacity.
