Detailed Description

The SoIndexedTriangleStripSet class keeps data for rendering and otherwise representing triangle strips.

Use nodes of this type as an effective way of drawing triangles which are strung together.

For more information, see the documentation of the GL_TRIANGLE_STRIP primitive rendering type in OpenGL.

For more information about indexed shapes, see documentation in SoIndexedShape and SoIndexedFaceSet.

Constructor & Destructor Documentation

SoIndexedTriangleStripSet::SoIndexedTriangleStripSet (  void )

Constructor. Default field values will equal those set in the SoIndexedShape parent class.

SoIndexedTriangleStripSet::~SoIndexedTriangleStripSet (  )  [protected, virtual]

Destructor.

Member Function Documentation

void SoIndexedTriangleStripSet::initClass (  void )  [static]

Sets up initialization for data common to all instances of this class, like submitting necessary information to the Coin type system. Reimplemented from SoIndexedShape.

void SoIndexedTriangleStripSet::GLRender (  SoGLRenderAction * action )  [virtual]

Action method for the SoGLRenderAction. This is called during rendering traversals. Nodes influencing the rendering state in any way or who wants to throw geometry primitives at OpenGL overrides this method. Reimplemented from SoShape.

void SoIndexedTriangleStripSet::getPrimitiveCount (  SoGetPrimitiveCountAction * action )  [virtual]

Action method for the SoGetPrimitiveCountAction. Calculates the number of triangle, line segment and point primitives for the node and adds these to the counters of the action. Nodes influencing how geometry nodes calculates their primitive count also overrides this method to change the relevant state variables. Reimplemented from SoShape.

SbBool SoIndexedTriangleStripSet::generateDefaultNormals (  SoState * state, SoNormalBundle * nb )  [virtual]

Overloaded to return FALSE. Normals are generated directly in normal cache. Reimplemented from SoVertexShape.

SbBool SoIndexedTriangleStripSet::willSetShadeModel (  void )  const [protected, virtual]

Overloaded to return TRUE, since shade model must be set to flat if normal or material binding is PER_FACE or PER_FACE_INDEXED.

SbBool SoIndexedTriangleStripSet::generateDefaultNormals (  SoState * state, SoNormalCache * nc )  [protected, virtual]

Subclasses should overload this method to generate default normals using the SoNormalCache class. This is more effective than using SoNormalGenerator. Return TRUE if normals were generated, FALSE otherwise. Default method just returns FALSE. This method is not part of the original OIV API. Do not overload it if you intend to create a node that can be used on both Coin and OIV. Reimplemented from SoVertexShape.

void SoIndexedTriangleStripSet::generatePrimitives (  SoAction * action )  [protected, virtual]

For internal use only. Reimplemented from SoShape.
