Interface Category:

API.

Inherits From:

MGraphic3D

Inherited By:

None.

Purpose:

TCone3D is a concrete class derived from MGraphic3D that represents a conical surface. Member functions are provided to set and get the radius and height. In addition, all the standard MGraphic3D member functions are implemented (Draw, GetGeometricBounds, TransformBy, and so on). A cone can also be generated using TSweep3D, but such an object can easily be altered beyond recognition. If you need to manipulate the cone in ways not provided by the TCone3D member functions, you can invoke TCone3D::CreateSweepSurface to access a TSweep3D with the same geometry and attributes as the TCone3D.

Instantiation:

Allocate on the heap or the stack.

Deriving Classes:

None.

Concurrency:

Not multithread safe.

Resource Use:

No special requirements.
