Detailed Description

Base class for all renderers that may to participate in 3D view.

3D renderers implement the method createEntity() that returns a new 3D entity - that entity will be added to the 3D scene to represent data in renderer's display style.

Renderers may store some custom properties (e.g. materials, sizes) that are written to and read from XML. It is therefore not recommended to store large amount of data within a renderer (e.g. arrays of vertices).
