class TGLClipPlane: public TGLClip
TGLClipPlane Concrete clip plane object. This can be translated in all directions rotated about the Y/Z local axes (the in-plane axes). It cannot be scaled.

TGLClipPlane()
Construct a clip plane object, based on supplied 'plane', with initial manipulation pivot at 'center', with drawn extents (in local x/y axes) of 'extents' Plane can have center pivot translated in all directions, and rotated round center in X/Y axes , the in-plane axes. It cannot be scaled Note theorectically a plane is of course infinite - however we want to draw the object in viewer - so we fake it with a single GL face (polygon) - extents defines the width/depth of this - should be several times scene extents - see Setup().
void Set(const TGLPlane& plane)
Update clip plane object to follow passed 'plane' equation. Center pivot is shifted to nearest point on new plane.
void PlaneSet(TGLPlaneSet_t& set) const
Return set of planes (actually a single one) describing this clip plane.
