.PP 
The \fBSoNonIndexedShape\fP class is the superclass for all non-indexed vertex based shapes\&.

It contains the (now obsoleted) startIndex field and a convenience method for calculating the bounding box\&.

.PP
Returns the type identification of an object derived from a class inheriting \fBSoBase\fP\&. This is used for run-time type checking and 'downward' casting\&. Usage example:
.PP
.PP
.nf
void foo(SoNode * node)
{
  if (node->getTypeId() == SoFile::getClassTypeId()) {
    SoFile * filenode = (SoFile *)node;  // safe downward cast, knows the type
  }
}
.fi

.PP
For application programmers wanting to extend the library with new nodes, engines, nodekits, draggers or others: this method needs to be overridden in \fIall\fP subclasses\&. This is typically done as part of setting up the full type system for extension classes, which is usually accomplished by using the pre-defined macros available through for instance \fBInventor/nodes/SoSubNode\&.h\fP (SO_NODE_INIT_CLASS and SO_NODE_CONSTRUCTOR for node classes), Inventor/engines/SoSubEngine\&.h (for engine classes) and so on\&.

.PP
Reimplemented from \fBSoVertexShape\fP\&.
.PP
Reimplemented in \fBSoFaceSet\fP, \fBSoLineSet\fP, \fBSoMarkerSet\fP, \fBSoPointSet\fP, \fBSoQuadMesh\fP, and \fBSoTriangleStripSet\fP\&.
.SS "const \fBSoFieldData\fP * SoNonIndexedShape::getFieldData (void) const\fC [protected]\fP, \fC [virtual]\fP"
Returns a pointer to the class-wide field data storage object for this instance\&. If no fields are present, returns \fCNULL\fP\&. 
.PP

Reimplemented in \fBSoFaceSet\fP, \fBSoLineSet\fP, \fBSoMarkerSet\fP, \fBSoPointSet\fP, \fBSoQuadMesh\fP, and \fBSoTriangleStripSet\fP\&.
.SS "void SoNonIndexedShape::computeCoordBBox (\fBSoAction\fP *action, intnumVertices, \fBSbBox3f\fP &box, \fBSbVec3f\fP &center)\fC [protected]\fP"
This method is provided as a convenient means for the subclasses of this class to find their bounding box and center value\&.
.PP
The returned bounding box will enclose all vertices from \fIstartIndex\fP up to \fIstartIndex\fP + \fInumVertices\fP\&. If \fInumVertices\fP is less than zero, \fIall\fP vertices in the current coordinate element or vertex property node will be used in the calculation\&.
.PP
The \fIcenter\fP point will be calculated as the average of all the vertices in the bounding box\&. 
.SS "void SoNonIndexedShape::fixNumVerticesPointers (\fBSoState\fP *state, const int32_t *&start, const int32_t *&end, int32_t *dummyarray) const\fC [protected]\fP"
Convenience method that might adjust \fIstart\fP and \fIend\fP pointers, which should point at the start and end of the numVertices array when calling this method\&. This takes care of the case where numVertices contains a single -1, and all coordinates in the state (or in the vertexProperty field) should be rendered as one primitive\&.
.PP
\fIdummyarray\fP should be a temporary array, with room for one integer\&.
.PP
Not part of the OIV API\&.
