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. SoFaceSet uses the coordinates in order, starting with the first one. Each face has a number of vertices specified by a value in the numVertices field. For example, an SoFaceSet with numVertices of [3,4,4] would use coordinates 1, 2, and 3 for the first face, coordinates 4, 5, 6, and 7 for the second face, and coordinates 8, 9, 10, and 11 for the third. 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 number of values in the numVertices field indicates the number of faces in the set. The coordinates of the face set are transformed by the current cumulative transformation. 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. The _INDEXED bindings are equivalent to their non-indexed counterparts. The default material binding is OVERALL. The default normal binding is PER_VERTEX. 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.


c } c } numVertices

Number of vertices per face.


c } c } SoFaceSet()

Creates a 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.
