Function documentation

TGLCylinder(const TBuffer3DTube& buffer)

 Copy out relevant parts of buffer - we create and delete mesh
 parts on demand in DirectDraw() and they are DL cached

~TGLCylinder()

destructor

UInt_t DLOffset(Short_t lod) const

 Return display-list offset for given LOD.
 Calculation based on what is done in virtual QuantizeShapeLOD below.

Short_t QuantizeShapeLOD(Short_t shapeLOD, Short_t combiLOD) const

 Factor in scene/viewer LOD and quantize.

void DirectDraw(TGLRnrCtx& rnrCtx) const

 Debug tracing

ELODAxes SupportedLODAxes() const

 Cylinders support LOD (tesselation quality) adjustment along
 X/Y axes (round the cylinder radius), but not along length (Z)

{ return ELODAxes(kLODAxesX | kLODAxesY); }
