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 typically hardware driver has lots of options and some settings can cause this mapper to produce artifacts.

Tests:

Member Function Documentation

virtual const char* vtkProjectedTetrahedraMapper::GetClassName (   )  [virtual]

Reimplemented from vtkUnstructuredGridVolumeMapper.

static int vtkProjectedTetrahedraMapper::IsTypeOf (  const char *  type  )  [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 vtkTypeRevisionMacro found in vtkSetGet.h. Reimplemented from vtkUnstructuredGridVolumeMapper.

virtual int vtkProjectedTetrahedraMapper::IsA (  const char *  type  )  [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 vtkTypeRevisionMacro found in vtkSetGet.h. Reimplemented from vtkUnstructuredGridVolumeMapper.

static vtkProjectedTetrahedraMapper* vtkProjectedTetrahedraMapper::SafeDownCast (  vtkObject *  o  )  [static]

Reimplemented from vtkUnstructuredGridVolumeMapper.

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

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

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.

virtual void vtkProjectedTetrahedraMapper::SetVisibilitySort (  vtkVisibilitySort *  sort  )  [virtual]

virtual vtkVisibilitySort* vtkProjectedTetrahedraMapper::GetVisibilitySort (   )  [virtual]

virtual void vtkProjectedTetrahedraMapper::SetScalarMode (  int   )  [virtual]

Control how the filter works with scalar point data and cell attribute data. By default (ScalarModeToDefault), the filter will use point data, and if no point data is available, then cell data is used. Alternatively you can explicitly set the filter to use point data (ScalarModeToUsePointData) or cell data (ScalarModeToUseCellData). You can also choose to get the scalars from an array in point field data (ScalarModeToUsePointFieldData) or cell field data (ScalarModeToUseCellFieldData). If scalars are coming from a field data array, you must call SelectColorArray before you call GetColors.

virtual void vtkProjectedTetrahedraMapper::SelectScalarArray (  int  arrayNum  )  [virtual]

When ScalarMode is set to UsePointFileData or UseCellFieldData, you can specify which array to use for coloring using these methods. The transfer function in the vtkVolumeProperty (attached to the calling vtkVolume) will decide how to convert vectors to colors.

virtual void vtkProjectedTetrahedraMapper::SelectScalarArray (  const char *  arrayName  )  [virtual]

When ScalarMode is set to UsePointFileData or UseCellFieldData, you can specify which array to use for coloring using these methods. The transfer function in the vtkVolumeProperty (attached to the calling vtkVolume) will decide how to convert vectors to colors.

virtual char* vtkProjectedTetrahedraMapper::GetArrayName (   )  [inline, virtual]

Get the array name or number and component to color by. Definition at line 100 of file vtkProjectedTetrahedraMapper.h.

virtual int vtkProjectedTetrahedraMapper::GetArrayId (   )  [inline, virtual]

Get the array name or number and component to color by. Definition at line 101 of file vtkProjectedTetrahedraMapper.h.

virtual int vtkProjectedTetrahedraMapper::GetArrayAccessMode (   )  [inline, virtual]

Get the array name or number and component to color by. Definition at line 102 of file vtkProjectedTetrahedraMapper.h.

const char* vtkProjectedTetrahedraMapper::GetScalarModeAsString (   )

Return the method for obtaining scalar data.

virtual void vtkProjectedTetrahedraMapper::Render (  vtkRenderer *  renderer, vtkVolume *  volume )  [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 vtkProjectedTetrahedraMapper::ReleaseGraphicsResources (  vtkWindow *  window  )  [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.

static void vtkProjectedTetrahedraMapper::MapScalarsToColors (  vtkDataArray *  colors, vtkVolume *  volume, vtkDataArray *  scalars )  [static]

virtual void vtkProjectedTetrahedraMapper::ProjectTetrahedra (  vtkRenderer *  renderer, vtkVolume *  volume )  [protected, virtual]

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.
