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] } }
FILE FORMAT/DEFAULTS:
IndexedMarkerSet { vertexProperty NULL coordIndex 0 materialIndex -1 normalIndex -1 textureCoordIndex -1 markerIndex -1 }
SoIndexedMarkerSet::SoIndexedMarkerSet | ( | void | ) |
Constructor.
SoIndexedMarkerSet::~SoIndexedMarkerSet | ( | ) | [protected, virtual] |
Destructor.
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.
