'vlrender' is a volume rendering program. The creation of 3d-renderings becomes straightforward since the appearance of the rendered volumes can be completely controlled within a graphical user interface (gui) in real-time. Clipping objects like planes or boxes can be placed freely to 'open up' parts of the volume and to show whats inside.
Anatomical and zmap data can be rendered in a single step to images of arbitrary size (resolution). Pre-rendering for standard anatomical MRI datasets is no longer required.
