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.
SoIndexedTriangleStripSet::SoIndexedTriangleStripSet | ( | void | ) |
Constructor. Default field values will equal those set in the SoIndexedShape parent class.
SoIndexedTriangleStripSet::~SoIndexedTriangleStripSet | ( | ) | [protected, virtual] |
Destructor.
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] |
Obsoleted, don't use.
SbBool SoIndexedTriangleStripSet::generateDefaultNormals | ( | SoState * | state, | |
SoNormalCache * | cache | |||
) | [protected, virtual] |
Subclasses should override 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 SGI Open Inventor API.
Reimplemented from SoVertexShape.
void SoIndexedTriangleStripSet::generatePrimitives | ( | SoAction * | action | ) | [protected, virtual] |
The method implements action behavior for shape nodes for SoCallbackAction. It is invoked from SoShape::callback(). (Subclasses should not override SoNode::callback().)
The subclass implementations uses the convenience methods SoShape::beginShape(), SoShape::shapeVertex(), and SoShape::endShape(), with SoDetail instances, to pass the primitives making up the shape back to the caller.
Implements SoShape.
