Detailed Description

OpenGL implementation of PT.

Bug:: This mapper relies highly on the implementation of the OpenGL pipeline. A typical hardware driver has lots of options and some settings can cause this mapper to produce artifacts.

Member Function Documentation

static int vtkOpenGLProjectedTetrahedraMapper::IsTypeOf ( const char * name ) [static]

Return 1 if this class type is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkProjectedTetrahedraMapper.

virtual int vtkOpenGLProjectedTetrahedraMapper::IsA ( const char * name ) [virtual]

Return 1 if this class is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkProjectedTetrahedraMapper.

static vtkOpenGLProjectedTetrahedraMapper* vtkOpenGLProjectedTetrahedraMapper::SafeDownCast ( vtkObjectBase * o ) [static]

Reimplemented from vtkProjectedTetrahedraMapper.

virtual vtkObjectBase* vtkOpenGLProjectedTetrahedraMapper::NewInstanceInternal ( ) const [protected, virtual]

Reimplemented from vtkProjectedTetrahedraMapper.

vtkOpenGLProjectedTetrahedraMapper* vtkOpenGLProjectedTetrahedraMapper::NewInstance ( ) const

Reimplemented from vtkProjectedTetrahedraMapper.

static vtkOpenGLProjectedTetrahedraMapper* vtkOpenGLProjectedTetrahedraMapper::New ( ) [static]

Create an object with Debug turned off, modified time initialized to zero, and reference counting on.

Reimplemented from vtkProjectedTetrahedraMapper.

virtual void vtkOpenGLProjectedTetrahedraMapper::PrintSelf	(	ostream &	os,
		vtkIndent	indent
	)		`[virtual]`

Methods invoked by print to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Reimplemented from vtkProjectedTetrahedraMapper.

virtual void vtkOpenGLProjectedTetrahedraMapper::ReleaseGraphicsResources ( vtkWindow * ) [virtual]

WARNING: INTERNAL METHOD - NOT INTENDED FOR GENERAL USE Release any graphics resources that are being consumed by this mapper. The parameter window could be used to determine which graphic resources to release.

Reimplemented from vtkUnstructuredGridVolumeMapper.

virtual void vtkOpenGLProjectedTetrahedraMapper::Render	(	vtkRenderer *	ren,
		vtkVolume *	vol
	)		`[virtual]`

WARNING: INTERNAL METHOD - NOT INTENDED FOR GENERAL USE DO NOT USE THIS METHOD OUTSIDE OF THE RENDERING PROCESS Render the volume

Implements vtkUnstructuredGridVolumeMapper.

virtual void vtkOpenGLProjectedTetrahedraMapper::SetUseFloatingPointFrameBuffer ( bool ) [virtual]

Set/get whether to use floating-point rendering buffers rather than the default.

virtual bool vtkOpenGLProjectedTetrahedraMapper::GetUseFloatingPointFrameBuffer ( ) [virtual]

Set/get whether to use floating-point rendering buffers rather than the default.

virtual void vtkOpenGLProjectedTetrahedraMapper::UseFloatingPointFrameBufferOn ( ) [virtual]

Set/get whether to use floating-point rendering buffers rather than the default.

virtual void vtkOpenGLProjectedTetrahedraMapper::UseFloatingPointFrameBufferOff ( ) [virtual]

Set/get whether to use floating-point rendering buffers rather than the default.

virtual bool vtkOpenGLProjectedTetrahedraMapper::IsSupported ( vtkRenderWindow * context ) [virtual]

Return true if the rendering context provides the nececessary functionality to use this class.

Reimplemented from vtkProjectedTetrahedraMapper.
