TGLVertex3 Class Reference

3 component (x/y/z) vertex class.

This is part of collection of simple utility classes for GL only in TGLUtil.h/cxx. These provide const and non-const accessors Arr() & CArr() to a GL compatible internal field - so can be used directly with OpenGL C API calls - which TVector3 etc cannot (easily). They are not intended to be fully featured just provide minimum required.
