NAME
SoNonIndexedShape -
The SoNonIndexedShape 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.
SYNOPSIS
#include <Inventor/nodes/SoNonIndexedShape.h>
Inherits SoVertexShape.
Inherited by SoFaceSet, SoLineSet, SoPointSet, SoQuadMesh, and
SoTriangleStripSet.

Detailed Description
The SoNonIndexedShape 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.

Member Function Documentation
void SoNonIndexedShape::initClass (void) [static] Sets up initialization
for data common to all instances of this class, like submitting
necessary information to the Coin type system.
Reimplemented from SoVertexShape.
Reimplemented in SoFaceSet, SoLineSet, SoMarkerSet, SoPointSet,
SoQuadMesh, and SoTriangleStripSet.
void SoNonIndexedShape::computeCoordBBox (SoAction * action, int
numVertices, SbBox3f & box, SbVec3f & center) [protected] This method
is provided as a convenient means for the subclasses of this class to
find their bounding box and center value.
The returned bounding box will enclose all vertices from startIndex up
to startIndex + numVertices. If numVertices is less than zero, all
vertices in the current coordinate element or vertex property node will
be used in the calculation.
The center point will be calculated as the average of all the vertices
in the bounding box.
void SoNonIndexedShape::fixNumVerticesPointers (SoState * state, const
int32_t *& start, const int32_t *& end, int32_t * dummyarray) const
[protected] Convenience method that might adjust start and end
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.
dummyarray should be a temporary array, with room for one integer.
Not part of the OIV API.

SoSFInt32 SoNonIndexedShape::startIndex Coordinates are fetched from this
index on. This field is now obsoleted, and is provided only for
backward compatibility.
