SoIndexedTriangleStripSet — indexed triangle strip set shape node
Contents
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 located at the coordinates specified in the
vertexProperty field (from SoVertexShape), or the current inherited coordinates. For optimal performance,
the vertexProperty field is recommended.
SoIndexedTriangleStripSet uses the indices in the coordIndex field (from SoIndexedShape) to specify the
vertices of the triangle strips. An index of SO_END_STRIP_INDEX (-1) indicates that the current strip has
ended and the next one begins.
The vertices of the faces are transformed by the current transformation matrix. The faces are drawn with
the current light model and drawing style.
Treatment of the current material and normal binding is as follows: PER_PART specifies a material or
normal per strip. PER_FACE binding specifies a material or normal for each triangle. PER_VERTEX specifies
a material or normal for each vertex. The corresponding _INDEXED bindings are the same, but use the
materialIndex or normalIndex indices (see SoIndexedShape). The default material binding is OVERALL. The
default normal binding is PER_VERTEX_INDEXED
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.
