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.

Member Data Documentation

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