Detailed Description

Unstructured grid volume renderer.

vtkProjectedTetrahedraMapper is an implementation of the classic Projected Tetrahedra algorithm presented by Shirley and Tuchman in "A Polygonal Approximation to Direct Scalar Volume Rendering" in Computer Graphics, December 1990.

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.

@par      Tests:
          @ref c2_vtk_t_vtkProjectedTetrahedraMapper "vtkProjectedTetrahedraMapper (Tests)"

static int vtkProjectedTetrahedraMapper::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 vtkUnstructuredGridVolumeMapper.

Reimplemented in vtkOpenGLProjectedTetrahedraMapper.

virtual int vtkProjectedTetrahedraMapper::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 vtkUnstructuredGridVolumeMapper.

Reimplemented in vtkOpenGLProjectedTetrahedraMapper.

static vtkProjectedTetrahedraMapper* vtkProjectedTetrahedraMapper::New

(

)

[static]

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

Reimplemented from vtkAlgorithm.

Reimplemented in vtkOpenGLProjectedTetrahedraMapper.

virtual void vtkProjectedTetrahedraMapper::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 vtkUnstructuredGridVolumeMapper.

Reimplemented in vtkOpenGLProjectedTetrahedraMapper.

virtual void vtkProjectedTetrahedraMapper::SetVisibilitySort

(

vtkVisibilitySort *

sort

[virtual]

static void vtkProjectedTetrahedraMapper::MapScalarsToColors	(	vtkDataArray *	colors,
		vtkVolumeProperty *	property,
		vtkDataArray *	scalars
	)		[static]

static void vtkProjectedTetrahedraMapper::TransformPoints	(	vtkPoints *	inPoints,
		const float	projection_mat[16],

		vtkFloatArray *	outPoints
	)		[static]

virtual void vtkProjectedTetrahedraMapper::ReportReferences

(

vtkGarbageCollector *

collector

[protected, virtual]

The visibility sort will probably make a reference loop by holding a reference to the input.

Reimplemented from vtkAlgorithm.
