       This  shape  node constructs quadrilaterals out of vertices. The vertices may be specified
       in the vertexProperty field (from SoVertexShape), or by the current inherited coordinates.
       For optimal performance, the vertexProperty field is recommended.

       SoQuadMesh  uses  the  coordinates,  in  order, starting with the first one. The number of
       vertices in the columns and rows of the mesh are specified by  the  verticesPerColumn  and
       verticesPerRow  fields.  (Note  that  these  numbers  are  1  greater  than  the number of
       quadrilaterals per row and per column.)

       For example, an SoQuadMesh with verticesPerColumn of 3, and verticesPerRow of 4 would  use
       coordinates  1,  2, 3, and 4 for the first row of vertices, coordinates 5, 6, 7, and 8 for
       the second row, and coordinates 9, 10, 11, and 12 for the third (last) row. The result  is
       a  mesh  of 3 quadrilaterals across by 2 down. Note: non-planar quadrilaterals formed by a
       quad mesh may cause interesting but unpredictable results.

       The coordinates of the mesh are transformed by the current cumulative transformation.  The
       mesh is drawn with the current light model and drawing style.

       Treatment  of  the current material and normal binding is as follows: The PER_PART binding
       specifies a material or normal for each row of the mesh. The PER_FACE binding specifies  a
       material  or  normal for each quadrilateral. The _INDEXED bindings are equivalent to their
       non-indexed counterparts. The default material binding  is  OVERALL.  The  default  normal
       binding is PER_VERTEX.

       If  any  normals  (or  materials)  are specified, Inventor assumes you provide the correct
       number of them, as indicated by the binding.  You  will  see  unexpected  results  if  you
       specify fewer normals (or materials) than the shape requires. If no normals are specified,
       they will be generated automatically.

          Creates a quadrilateral mesh node with default settings.

     static SoType       getClassTypeId()
          Returns type identifier for this class.


          Draws a mesh based on the current coordinates, normals, materials, drawing  style,  and
          so on.

          Picks  on  the  mesh based on the current coordinates and transformation. Details about
          the intersection are returned in an SoFaceDetail.

          Computes the bounding box that encloses all vertices  of  the  mesh  with  the  current
          transformation  applied  to  them. Sets the center to the average of the coordinates of
          all vertices.

          If any triangle callbacks are registered with the action, they will be invoked for each
          successive triangle forming the quadrilaterals of the mesh.
