// Class: SoNonIndexedShape
//
// Abstract nonindexed shape node class. All nodes derived from this
// (such as SoFaceSet and SoTriangleStripSet) are shapes constructed
// from vertices defined by consecutive entries in the current
// coordinates. The startIndex field gives the index into the current
// coordinates at which the shape begins.

// This is a convenience method to simplify the job of computing
// bounding boxes for subclasses; it can be called from a
// subclass's computeBBox() method. It sets the given bounding box
// to contain all vertices of the shape, assuming that the shape
// uses the numVertices coordinates beginning at the value in
// startIndex. (If numVertices is negative, it uses all
// coordinates from startIndex on.) It also sets the center to the
// average of the vertices' coordinates.
