Class defines a Clipping Volume as a logical OR (disjunction) operation between Graphic3d_ClipPlane in sequence. Each Graphic3d_ClipPlane represents either a single Plane clipping a halfspace (direction is specified by normal), or a sub-chain of planes defining a logical AND (conjunction) operation. Therefore, this collection allows defining a Clipping Volume through the limited set of Boolean operations between clipping Planes. More...

Detailed Description

Class defines a Clipping Volume as a logical OR (disjunction) operation between Graphic3d_ClipPlane in sequence. Each Graphic3d_ClipPlane represents either a single Plane clipping a halfspace (direction is specified by normal), or a sub-chain of planes defining a logical AND (conjunction) operation. Therefore, this collection allows defining a Clipping Volume through the limited set of Boolean operations between clipping Planes.

The Clipping Volume can be assigned either to entire View or to a specific Object; in the latter case property ToOverrideGlobal() will specify if Object planes should override (suppress) globally defined ones or extend their definition through logical OR (disjunction) operation.

Note that defining (many) planes will lead to performance degradation, and Graphics Driver may limit the overall number of simultaneously active clipping planes - but at least 6 planes should be supported on all configurations.
