TGLPhysicalShape
Concrete physical shape - a GL drawable. Physical shapes are the
objects the user can actually see, select, move in the viewer. It is
a placement of the associated local frame TGLLogicaShape into the
world frame. The draw process is:
Load attributes - material colors etc
Load translation matrix - placement
Load gl name (for selection)
Call our associated logical shape Draw() to draw placed shape
The physical shape supports translation, scaling and rotation,
selection, color changes, and permitted modification flags etc.
A physical shape cannot modify or be bound to another (or no)
logical shape - hence const & handle. It can perform mutable
reference counting on the logical to enable purging.
See base/src/TVirtualViewer3D for description of common external 3D
viewer architecture and how external viewer clients use it.

Construct a physical shape using arguments:
ID - unique drawable id.
logicalShape - bound logical shape
transform - transform for placement of logical drawing
invertedWind - use inverted face polygon winding?
rgba - basic four component (RGBA) diffuse color

logicalShape - bound logical shape
transform - 16 Double_t component transform for placement of logical drawing
invertedWind - use inverted face polygon winding?
rgba - basic four component (RGBA) diffuse color
~TGLPhysicalShape()
Destroy logical shape
void UpdateBoundingBox()
Update our internal bounding box (in global frame)
void InitColor(const Float_t rgba[4])
Initialise the colors, using basic RGBA diffuse material color supplied
void SetColor(const Float_t color[17])
Set full color attributes - see OpenGL material documentation
for full description
0...3 - diffuse
4...7 - ambient
8...11 - specular
12..15 - emission
16 - shininess
void Draw(UInt_t LOD) const
Draw physical shape, using LOD flags, potential from display list cache
