Detailed DescriptionThe SoIndexedMarkerSet class is used to display a set of bitmap markers at 3D positions​. This node either uses the coordinates currently on the state (typically set up by a leading SoCoordinate3 node in the scenegraph) or from a SoVertexProperty node attached to this node to render a set of 3D points​. To add new markers, use the static functions in SoMarkerSet​. Here's a simple usage example of SoIndexedMarkerSet in a scenegraph: #Inventor V2.1 ascii Separator { Material { diffuseColor [ 1 0 0, 0 1 0, 0 0 1, 1 1 0, 1 0 1, 1 1 1, 1 0.8 0.6, 0.6 0.8 1 ] } MaterialBinding { value PER_VERTEX_INDEXED } Coordinate3 { point [ -1 1 0, -1 -1 0, 1 -1 0, 1 1 0, 0 2 -1, -2 0 -1, 0 -2 -1, 2 0 -1 ] } IndexedMarkerSet { coordIndex [0, 1, 2, 3, 4, 5, 6, 7] markerIndex [0, 1, 0, 1, 0, 1, 0, 1] } }.fiFILE FORMAT/DEFAULTS: IndexedMarkerSet { vertexProperty NULL coordIndex 0 materialIndex -1 normalIndex -1 textureCoordIndex -1 markerIndex -1 } Since TGS Inventor 6​.0, Coin 3​.1

Member Function Documentation
SoType SoIndexedMarkerSet::getTypeId (void) const [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: void foo(SoNode * node) { if (node->getTypeId() == SoFile::getClassTypeId()) { SoFile * filenode = (SoFile *)node; // safe downward cast, knows the type } }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​. Reimplemented from SoIndexedPointSet​.
const SoFieldData * SoIndexedMarkerSet::getFieldData (void) const [protected], [virtual]Returns a pointer to the class-wide field data storage object for this instance​. If no fields are present, returns NULL​. Reimplemented from SoIndexedPointSet​.
void SoIndexedMarkerSet::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 SoIndexedPointSet​.
