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.

   SoNonIndexedShape::~SoNonIndexedShape () [protected, virtual] Destructor.

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, intnumVertices, 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.

       is now obsoleted, and is provided only for backward compatibility.
