Class Description

                                                                      
 TGLVertex3                                                           
                                                                      
 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.
TGLVertex3()
 Construct a default (0.0, 0.0, 0.0) vertex
TGLVertex3(Double_t x, Double_t y, Double_t z)
 Construct a vertex with components (x,y,z)
TGLVertex3(const TGLVertex3 & other)
 Construct a vertex from 'other'
~TGLVertex3()
 Destroy vertex object
void Shift(TGLVector3 & shift)
 Offset a vertex by vector 'shift'
void Shift(Double_t xDelta, Double_t yDelta, Double_t zDelta)
 Offset a vertex by components (xDelta, yDelta, zDelta)
void Dump()
 Output vertex component values to std::cout
void Negate()
