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
Page 2SoIndexedTriangleStripSet(3IV)
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.
FUNCTIONSSoIndexedTriangleStripSet * SoIndTriStripSetCreate()
Creates an indexed triangle strip set node with default settings.
SoType SoIndTriStripSetGetClassTypeId()
Returns type identifier for this class.
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.
