TGLVector3 Class Reference

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

This is part of collection of utility classes for GL 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. They are not intended to be fully featured just provide minimum required.
