Detailed Description

The 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]
     }
  }

Member Function Documentation

SoType SoIndexedMarkerSet::getClassTypeId ( void  )
static

This static method returns the SoType object associated with objects of this class.

Reimplemented from SoIndexedPointSet.

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::getFieldDataPtr ( void  )
staticprotected

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

Reimplemented from SoIndexedPointSet.

const SoFieldData * SoIndexedMarkerSet::getFieldData ( void  ) const
protectedvirtual

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::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 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.

void SoIndexedMarkerSet::notify ( SoNotList l)
virtual

Notifies all auditors for this instance when changes are made.

Reimplemented from SoIndexedPointSet.
