Member Function Documentation

◆ Class()

static TClass * TPointSet3DGL::Class ( )
static
Returns
TClass describing this class

static const char * TPointSet3DGL::Class_Name ( )
static
Returns
Name of this class

◆ Class_Version()

static constexpr Version_t TPointSet3DGL::Class_Version ( )
inlinestaticconstexpr
Returns
Version of this class

Definition at line 38 of file TPointSet3DGL.h.

◆ DeclFileName()

static const char * TPointSet3DGL::DeclFileName ( )
inlinestatic
Returns
Name of the file containing the class declaration

Definition at line 38 of file TPointSet3DGL.h.

◆ DirectDraw()

void TPointSet3DGL::DirectDraw ( TGLRnrCtx rnrCtx) const
overridevirtual

Direct GL rendering for TPointSet3D.

Implements TGLLogicalShape.

Definition at line 72 of file TPointSet3DGL.cxx.

◆ Draw()

void TPointSet3DGL::Draw ( TGLRnrCtx rnrCtx) const
overridevirtual

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

Reimplemented from TGLLogicalShape.

Definition at line 61 of file TPointSet3DGL.cxx.

◆ IgnoreSizeForOfInterest()

Bool_t TPointSet3DGL::IgnoreSizeForOfInterest ( ) const
inlineoverridevirtual

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.

◆ IsA()

TClass * TPointSet3DGL::IsA ( ) const
inlineoverridevirtual
Returns
TClass describing current object

Reimplemented from TGLObject.

Definition at line 38 of file TPointSet3DGL.h.

◆ ProcessSelection()

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

Processes secondary selection from TGLViewer.

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

Reimplemented from TGLLogicalShape.

Definition at line 92 of file TPointSet3DGL.cxx.

◆ SetBBox()

void TPointSet3DGL::SetBBox ( )
overridevirtual

Set bounding-box.

Implements TGLObject.

Definition at line 41 of file TPointSet3DGL.cxx.

◆ SetModel()

Bool_t TPointSet3DGL::SetModel ( TObject obj,
const Option_t opt = nullptr 
)
overridevirtual

Set model.

Implements TGLObject.

◆ ShouldDLCache()

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

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.

◆ Streamer()

void TPointSet3DGL::Streamer ( TBuffer )
overridevirtual

Reimplemented from TGLObject.

◆ StreamerNVirtual()

void TPointSet3DGL::StreamerNVirtual ( TBuffer ClassDef_StreamerNVirtual_b)
inline

Definition at line 38 of file TPointSet3DGL.h.

◆ SupportsSecondarySelect()

Bool_t TPointSet3DGL::SupportsSecondarySelect ( ) const
inlineoverridevirtual

Reimplemented from TGLLogicalShape.
