Purpose

The module View3D can be used to do volume rendering of a 3D dataset.

It encapsulates the complex features of the SoGVRVolumeRenderer module and provides access to the basic rendering features.

Details

The interface is split into the render area on the left and the parameters panel on the right. It is recommended that your graphic hardware supports 3D Texture mapping.

The renderer has been tested on modern ATI and nVidia boards but also works on older Notebook hardware.

The 2D texture implementation is quite slow, so it is recommended to use the renderer on better hardware.
