The VIEW libary currently contains two methods for rendering visualisations:
The obviously most import is the OPENGL renderer which provides hardware acceleration and is e.g. used in the Scene.
In addition it is possible to export a Representation into POVRay format by using the class POVRenderer. This enables high quality rendering of single images e.g. for high resolution images in publications.
If you want to add support for a new type of rendering, create a new derived Renderer class.
