Function documentation

Bool_t SetModel(TObject* obj, Option_t* opt = 0)
 Set model.
void SetBBox()
 Set bounding-box.
Bool_t ShouldDLCache(const TGLRnrCtx& rnrCtx) const
 Override from TGLDrawable.
 To account for large point-sizes we modify the projection matrix
 during selection and thus we need a direct draw.
void Draw(TGLRnrCtx& rnrCtx) const
 Draw function for TPointSet3D. Skips line-pass of outline mode.
void DirectDraw(TGLRnrCtx& rnrCtx) const
 Direct GL rendering for TPointSet3D.
void RenderPoints(TGLRnrCtx& rnrCtx) const
 Render markers as circular or square points.
void RenderCrosses(TGLRnrCtx& rnrCtx) const
 Render markers as crosses.
void ProcessSelection(TGLRnrCtx& rnrCtx, TGLSelectRecord& rec)
 Processes secondary selection from TGLViewer.
 Calls TPointSet3D::PointSelected(Int_t) with index of selected
 point as an argument.
TPointSet3DGL()
{}
Bool_t IgnoreSizeForOfInterest()
{ return kTRUE; }
Bool_t SupportsSecondarySelect()
{ return kTRUE; }
