Detailed Description

The SoGetPrimitiveCountAction class counts the primitives in a scene.

Apply this action to a scene if you need to know the number of primitives present.

SoGetPrimitiveCountAction::SoGetPrimitiveCountAction (  void    )

Constructor.

SoGetPrimitiveCountAction::~SoGetPrimitiveCountAction (    )  [virtual]

The destructor.

Member Function Documentation

void SoGetPrimitiveCountAction::initClass (  void    )  [static]

Initializes the run-time type system for this class, and sets up the enabled elements and action method list. Reimplemented from SoAction.

int SoGetPrimitiveCountAction::getTriangleCount (  void    )  const

Returns number of triangles in graph.

int SoGetPrimitiveCountAction::getLineCount (  void    )  const

Returns number of lines in graph.

int SoGetPrimitiveCountAction::getPointCount (  void    )  const

Returns number of points in graph.

int SoGetPrimitiveCountAction::getTextCount (  void    )  const

Returns number of texts in the graph.

int SoGetPrimitiveCountAction::getImageCount (  void    )  const

Returns the number of images in the graph.

SbBool SoGetPrimitiveCountAction::containsNoPrimitives (  void    )

Returns whether there are any primitives in graph or not.

SbBool SoGetPrimitiveCountAction::containsNonTriangleShapes (  void    )

Returns whether there are non-triangular primitives in graph.

SbBool SoGetPrimitiveCountAction::is3DTextCountedAsTriangles (  void    )

Returns whether SoText3 nodes is counted as triangles or text. See also: is3DTextCountedAsTriangles()

void SoGetPrimitiveCountAction::setCount3DTextAsTriangles (  const SbBool    flag )

Sets whether SoText3 nodes are counted as the triangles of the fonts in the text strings or the text itself. The default is to count as triangles. See also: is3DTextCountedAsTriangles()

SbBool SoGetPrimitiveCountAction::canApproximateCount (  void    )

Returns whether shapes can use an approximate value when counting primitives. This is faster than doing an accurate count. The default is to not approximate. See also: setCanApproximate()

void SoGetPrimitiveCountAction::setCanApproximate (  const SbBool    flag )

Sets whether shapes can do an approximate count. See also: canApproximateCount()

void SoGetPrimitiveCountAction::setDecimationValue (  SoDecimationTypeElement::Type    type, float    percentage = 1.0 )

Set up the decimation parameters for the traversal. On-the-fly decimation is supported in Coin yet, so this call will not have any effect until this feature has been implemented.

SoDecimationTypeElement::Type SoGetPrimitiveCountAction::getDecimationType (  void    )

Returns decimation type used during the traversal count.

float SoGetPrimitiveCountAction::getDecimationPercentage (  void    )

Returns decimation percentage used during the traversal count.

void SoGetPrimitiveCountAction::addNumTriangles (  const int    num )

Adds num triangles to total count. Used by node instances in the scene graph during traversal.

void SoGetPrimitiveCountAction::addNumLines (  const int    num )

Adds num lines to total count. Used by node instances in the scene graph during traversal.

void SoGetPrimitiveCountAction::addNumPoints (  const int    num )

Adds num points to total count. Used by node instances in the scene graph during traversal.

void SoGetPrimitiveCountAction::addNumText (  const int    num )

Adds num texts to total count. Used by node instances in the scene graph during traversal.

void SoGetPrimitiveCountAction::addNumImage (  const int    num )

Adds num texture image maps to total count. Used by node instances in the scene graph during traversal.

void SoGetPrimitiveCountAction::incNumTriangles (  void    )

Adds a single triangle to the total count. Used by node instances in the scene graph during traversal.

void SoGetPrimitiveCountAction::incNumLines (  void    )

Adds a single line to the total count. Used by node instances in the scene graph during traversal.

void SoGetPrimitiveCountAction::incNumPoints (  void    )

Adds a single point to the total count. Used by node instances in the scene graph during traversal.

void SoGetPrimitiveCountAction::incNumText (  void    )

Adds a single text to the total count. Used by node instances in the scene graph during traversal.

void SoGetPrimitiveCountAction::incNumImage (  void    )

Adds a single texture image map to the total count. Used by node instances in the scene graph during traversal.

void SoGetPrimitiveCountAction::beginTraversal (  SoNode *    node )  [protected, virtual]

Overloaded to reset all counters to zero before traversal starts. Reimplemented from SoAction.
