SoNonIndexedShape – abstract base class for all non-indexed vertex-based shapes
This node is the abstract base class for all vertex-based shapes that are not constructed from indices, such as
SoFaceSet,
SoLineSet, and
SoQuadMesh.
All subclasses of
SoNonIndexedShape construct objects by using the coordinates specified in the
vertexProperty
field (from
SoVertexShape), or the current inherited coordinates. The
startIndex field defined by this class is now obsolete, and is provided here only for compatibility with old files and programs.
The subclass decides what
to do with this and any subsequent coordinates. The shape is drawn with the current lighting model and drawing style and is transformed by the current transformation matrix.
Material, normal, and texture
coordinate bindings for shapes derived from this class ignore any index specifications. That is, a binding value of
PER_FACE_INDEXED is treated the same way as
PER_FACE, and so on.
If there aren't sufficient values in the current
coordinates, material, or texture coordinates, errors will occur.
This is an abstract class. See the reference page of a derived class for the format and default values.
