class TGLClipSet: public TGLOverlayElement


TGLClip

Abstract clipping shape - derives from TGLPhysicalShape
Adds clip mode (inside/outside) and pure virtual method to
 approximate shape as set of planes. This plane set is used to perform
interactive clipping using OpenGL clip planes.

Function documentation

TGLClipSet()

 Constructor.

~TGLClipSet()

 Destructor.

Bool_t MouseEnter(TGLOvlSelectRecord& selRec)

 Mouse has enetered this element.
 Forward to ManipSet.

Bool_t MouseStillInside(TGLOvlSelectRecord& selRec)

 A new overlay hit is about to be processed.
 Forward to ManipSet.

Bool_t Handle(TGLRnrCtx& rnrCtx, TGLOvlSelectRecord& selRec, Event_t* event)

 Handle overlay event.
 Forward to ManipSet.

void MouseLeave()

 Mouse has left the element.
 Forward to ManipSet.

void Render(TGLRnrCtx& rnrCtx)

 Render clip-shape and manipulator.

void FillPlaneSet(TGLPlaneSet_t& set) const

 Forward request to fill the plane-set to the current clip.

void SetupClips(const TGLBoundingBox& sceneBBox)

 Setup clipping objects for current scene bounding box.

void GetClipState(EClipType type, Double_t* data) const

 Get state of clip object 'type' into data vector:

 'type' requested - 'data' contents returned
 kClipPlane   4 components - A,B,C,D - of plane eq : Ax+By+CZ+D = 0
 kBoxPlane    6 components - Box Center X/Y/Z - Box Extents X/Y/Z

void SetClipState(EClipType type, const Double_t* data)

 Set state of clip object 'type' into data vector:

 'type' specified        'data' contents interpretation
 kClipNone               ignored
 kClipPlane              4 components - A,B,C,D - of plane eq : Ax+By+CZ+D = 0
 kBoxPlane               6 components - Box Center X/Y/Z - Box Extents X/Y/Z

EClipType GetClipType()

 Get current type active in viewer - returns one of kClipNone
 kClipPlane or kClipBox.

void SetClipType(EClipType type)

 Set current clip active in viewer - 'type' is one of kClipNone
 kClipPlane or kClipBox.

Bool_t IsClipping()

{ return fCurrentClip != 0; }

TGLClip * GetCurrentClip()

{ return fCurrentClip; }

Bool_t GetShowManip()

 Editor only supports combined flag so far.

{ return fShowManip; }

void SetShowManip(Bool_t show)

{ fShowManip = show; }

Bool_t GetShowClip()

{ return fShowClip; }

void SetShowClip(Bool_t show)

{ fShowClip = show; }
