DESCRIPTION
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.
Page 2SoIndexedFaceSet(3IV)FUNCTIONSSoIndexedFaceSet * SoIndFSetCreate()
Creates an indexed face set node with default settings.
SoType SoIndFSetGetClassTypeId()
Returns type identifier for this class.
ACTION BEHAVIOR
SoGLRenderAction
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.
