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.

METHODS¶

SoIndexedTriangleStripSet()
Creates an indexed triangle strip set node with default settings.

static SoType getClassTypeId()
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.
