This node represents a 3D shape formed by constructing faces (polygons) from vertices located at the coordinates specified in the vertexProperty field (from SoVertexShape), or the current inherited state. For optimal performance, the vertexProperty field is recommended. SoIndexedFaceSet uses the indices in the coordIndex field (from SoIndexedShape) to specify the polygonal faces. An index of SO_END_FACE_INDEX (-1) indicates that the current face has ended and the next one begins. For improved performance, arrange all the faces with only 3 vertices at beginning of the list, then all faces with 4 vertices, and finally all other faces. The vertices of the faces are transformed by the current transformation matrix. The faces are drawn with the current light model and drawing style. Treatment of the current material and normal binding is as follows: The PER_PART and PER_FACE bindings specify a material or normal for each face. PER_VERTEX specifies a material or normal for each vertex. The corresponding _INDEXED bindings are the same, but use the materialIndex or normalIndex indices (see SoIndexedShape). The default material binding is OVERALL. The default normal binding is PER_VERTEX_INDEXED. If any normals (or materials) are specified, Inventor assumes you provide the correct number of them, as indicated by the binding. You will see unexpected results if you specify fewer normals (or materials) than the shape requires. If no normals are specified, they will be generated automatically. Textures are applied as described for the SoIndexedShape class.


c } c } SoIndexedFaceSet()

Creates an indexed face set node with default settings. c } c } getClassTypeId()

Returns type identifier for this class.



Draws faces based on the current coordinates, normals, materials, drawing style, and so on. SoRayPickAction

Picks faces based on the current coordinates and transformation. Details about the intersection are returned in an SoFaceDetail. SoGetBoundingBoxAction

Computes the bounding box that encloses all vertices of the face set with the current transformation applied to them. Sets the center to the average of the coordinates of all vertices. SoCallbackAction

If any triangle callbacks are registered with the action, they will be invoked for each successive triangle generated from each face in the set.
