Detailed Description

Class MathGeometry presents geometry for next rendering that was generated with math representation.

MathGeometry class takes a pointer to MbItem math representation for the next generating visual representation. MbItem can presents such objects as MbSolid, MbMesh, MbСontour, etc that are able to generate a polygonal model independently. MathGeometry class presents a set of useful functions. You can use SetVisualSag function to compute a triangulation step of planes and faces and you can call regeneration of triangulation in real time, what influences quality of geometry display. You can get primitive identification from visual representation to math one and vice versa using QueryMathByGeometry and QueryGeomByMath functions. It's necessary to know that identifiers of math representation are hash of real identifiers and paths to these primitives.
