SoTriangleStripSet — triangle strip set shape node

Action Behavior

SoGLRenderAction
          Draws a strip set based on the current coordinates, normals, materials, drawing style, and so on.

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

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

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

Description

       This  shape  node  constructs  triangle  strips  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.

       SoTriangleStripSet  is  one  of  the  fastest  ways of drawing polygonal objects in Inventor. It uses the
       current coordinates, in order, starting with the first one. The values in the numVertices field  indicate
       the  number  of  vertices  to  use for each triangle strip in the set. The number of values in this field
       determines the number of strips.

       For example, if numVertices has the values [3,5], coordinates 1, 2, and 3 would be  used  for  the  first
       triangle strip and coordinates 4, 5, 6, 7, and 8 would be used for the second strip. This would result in
       1 triangle in the first strip and 3 in the second.

       The  coordinates  of  the strips are transformed by the current cumulative transformation. The strips are
       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 strip of the set. The PER_FACE binding specifies a material or normal for
       each triangle. The _INDEXED bindings are equivalent to their non-indexed counterparts. The default normal
       binding is PER_VERTEX. The default material binding is OVERALL.

       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.

Fields

SoMFInt32numVertices
          Number of vertices in each triangle strip. The number of strips is equal to the number  of  values  in
          this field.
