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 SoTriangleStripSet node.
To render several strips within the same node, just separate the coordinate indices with -1. For more information about indexed shapes, see documentation in SoIndexedShape and SoIndexedFaceSet.
Example scene graph:
#Inventor V2.1 ascii Separator { Coordinate3 { point [ -2 1 0, -1 -1 0, 0 1 0, 1 -1 0, 2 1 0, # first strip, z==0 -2 1 5, -1 -1 5, 0 1 5, 1 -1 5, 2 1 5 # second strip, z==5 ] } IndexedTriangleStripSet { coordIndex [ 0, 1, 2, 3, 4, -1, 5, 6, 7, 8, 9, -1 ] } }
FILE FORMAT/DEFAULTS:
SoIndexedTriangleStripSet::SoIndexedTriangleStripSet | ( | void | ) |
Constructor. Default field values will equal those set in the SoIndexedShape parent class.
|
protectedvirtual |
Destructor.
|
static |
This static method returns the SoType object associated with objects of this class.
Reimplemented from SoIndexedShape.
|
virtual |
Returns the type identification of an object derived from a class inheriting SoBase. This is used for run-time type checking and "downward" casting.
Usage example:
For application programmers wanting to extend the library with new nodes, engines, nodekits, draggers or others: this method needs to be overridden in all subclasses. This is typically done as part of setting up the full type system for extension classes, which is usually accomplished by using the pre-defined macros available through for instance Inventor/nodes/SoSubNode.h (SO_NODE_INIT_CLASS and SO_NODE_CONSTRUCTOR for node classes), Inventor/engines/SoSubEngine.h (for engine classes) and so on.
For more information on writing Coin extensions, see the class documentation of the toplevel superclasses for the various class groups.

This API member is considered internal to the library, as it is not likely to be of interest to the application programmer.
Reimplemented from SoIndexedShape.
|
protectedvirtual |
Returns a pointer to the class-wide field data storage object for this instance. If no fields are present, returns NULL
.
Reimplemented from SoIndexedShape.
|
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.

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.

|
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.
References SoGetPrimitiveCountAction::addNumTriangles(), SoGetPrimitiveCountAction::canApproximateCount(), SoIndexedShape::coordIndex, SoMField::getNum(), and SoShape::shouldPrimitiveCount().

virtual |
This API member is considered internal to the library, as it is not likely to be of interest to the application programmer.
Subclasses should override this method to generate default normals using the SoNormalBundle class. TRUE
should be returned if normals were generated, FALSE
otherwise.
Default method returns FALSE
.
This function is an extension for Coin, and it is not available in the original SGI Open Inventor v2.1 API.
Reimplemented from SoVertexShape.

protectedvirtual |
This API member is considered internal to the library, as it is not likely to be of interest to the application programmer.
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
.

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.
