Function documentation

TGLSphere(const TBuffer3DSphere& buffer)
 Default ctor
UInt_t DLOffset(Short_t lod) const
 Return display-list offset for given LOD.

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()
{ return kLODAxesAll; }
