Class Description

 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.

TGLPlane()

 Construct a default plane of x + y + z = 0

TGLPlane(const TGLPlane & other)

 Construct plane from 'other'

TGLPlane(Double_t a, Double_t b, Double_t c, Double_t d)

 Construct plane with equation a.x + b.y + c.z + d = 0
 with optional normalisation

TGLPlane(Double_t eq[4])

 Construct plane with equation eq[0].x + eq[1].y + eq[2].z + eq[3] = 0
 with optional normalisation

TGLPlane(const TGLVertex3 & p1, const TGLVertex3 & p2, const TGLVertex3 & p3)

 Construct plane passing through 3 supplied points
 with optional normalisation

TGLPlane(const TGLVector3 & v, const TGLVertex3 & p)

 Construct plane with supplied normal vector, passing through point
 with optional normalisation

~TGLPlane()

 Destroy plane object

void Dump() const

 Output plane equation to std::out
