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.

TGLLine3(const TGLVertex3 & start, const TGLVertex3 & end)

 Construct 3D line running from 'start' to 'end'

TGLLine3(const TGLVertex3 & start, const TGLVector3 & vect)

 Construct 3D line running from 'start', magnitude 'vect'

~TGLLine3()

 Destroy 3D line object

void Set(const TGLVertex3 & start, const TGLVertex3 & end)

 Set 3D line running from 'start' to 'end'

void Set(const TGLVertex3 & start, const TGLVector3 & vect)

 Set 3D line running from start, magnitude 'vect'

void Draw()

 Draw line in current basic GL color. Assume we are in the correct reference
 frame

TGLLine3(const TGLVertex3 & start, const TGLVertex3 & end)

const TGLVertex3 & Start()

 Accessors

{ return fVertex; }

const TGLVertex3 End()

{ return fVertex + fVector; }

const TGLVector3 & Vector()

{ return fVector; }

TGLUtil& operator=(const TGLUtil& glu)
