Remarks

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

OIV.Inventor.Nodes.SoTriangleStripSet is one of the fastest ways of drawing polygonal objects in Open Inventor. It uses the current coordinates, in order, starting with the first one. The values in the OIV.Inventor.Nodes.SoTriangleStripSet.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 OIV.Inventor.Nodes.SoTriangleStripSet.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, Open 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.

To render triangles that are not in strips, see the OIV.Inventor.Nodes.SoTriangleSet node.

Limitations:

FILE FORMAT/DEFAULT

TriangleStripSet {
vertexProperty NULL
startIndex 0
numVertices -1
}

ACTION BEHAVIOR

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

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

OIV.Inventor.Actions.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.

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