Detailed Description

Container of graphical resources for rendering capping plane associated to graphical clipping plane. This resource holds data necessary for OpenGl_CappingAlgo. This object is implemented as OpenGl resource for the following reasons:

• one instance should be shared between contexts.
• instance associated to Graphic3d_ClipPlane data by id.
• should created and released within context (owns OpenGl elements and resources).
