Definition at line 23 of file TPointSet3DGL.h.

Member Function Documentation

◆ DirectDraw()

void TPointSet3DGL::DirectDraw ( TGLRnrCtx & rnrCtx ) const

virtual

Direct GL rendering for TPointSet3D.

Implements TGLLogicalShape.

Reimplemented in TEveLineGL, TEveTrackGL, and TEveTrackProjectedGL.

Definition at line 72 of file TPointSet3DGL.cxx.

◆ Draw()

void TPointSet3DGL::Draw ( TGLRnrCtx & rnrCtx ) const

virtual

Draw function for TPointSet3D. Skips line-pass of outline mode.

Reimplemented from TGLLogicalShape.

Definition at line 61 of file TPointSet3DGL.cxx.

◆ IgnoreSizeForOfInterest()

virtual Bool_t TPointSet3DGL::IgnoreSizeForOfInterest ( ) const

inlinevirtual

Return true if size of this shape should be ignored when determining if the object should be drawn.

In this base-class we simply return state of static flag fgIgnoreSizeForCameraInterest.

Several sub-classes override this virtual function.

Reimplemented from TGLLogicalShape.

Definition at line 29 of file TPointSet3DGL.h.

◆ ProcessSelection()

void TPointSet3DGL::ProcessSelection	(	TGLRnrCtx &	rnrCtx,
		TGLSelectRecord &	rec
	)

virtual

Processes secondary selection from TGLViewer.

Calls TPointSet3D::PointSelected(Int_t) with index of selected point as an argument.

Reimplemented from TGLLogicalShape.

Reimplemented in TEveTrackGL.

Definition at line 92 of file TPointSet3DGL.cxx.

◆ SetBBox()

void TPointSet3DGL::SetBBox ( )

virtual

Set bounding-box.

Implements TGLObject.

Definition at line 41 of file TPointSet3DGL.cxx.

◆ SetModel()

Bool_t TPointSet3DGL::SetModel	(	TObject *	obj,
		const Option_t *	opt = `0`
	)

virtual

Set model.

Implements TGLObject.

Reimplemented in TEveLineGL, TEveTrackGL, and TEveTrackProjectedGL.

Definition at line 33 of file TPointSet3DGL.cxx.

◆ ShouldDLCache()

Bool_t TPointSet3DGL::ShouldDLCache ( const TGLRnrCtx & rnrCtx ) const

virtual

Override from TGLLogicalShape.

To account for large point-sizes we modify the projection matrix during selection and thus we need a direct draw.

Reimplemented from TGLObject.

Definition at line 51 of file TPointSet3DGL.cxx.

◆ SupportsSecondarySelect()

virtual Bool_t TPointSet3DGL::SupportsSecondarySelect ( ) const

inlinevirtual

Reimplemented from TGLLogicalShape.

Reimplemented in TEveTrackGL.

Definition at line 35 of file TPointSet3DGL.h.
