public class SoIndexedTriangleSet extends SoIndexedShape
SoVertexShape), or the current inherited state. For optimal performance, the
vertexPropertyfield is recommended.
SoIndexedTriangleSet uses the indices in the coordIndex field (from
SoIndexedShape) to specify the vertices of the triangles. Each triangle is specified by three indices. Unlike
SoIndexedFaceSet (for example) no -1 values are needed or allowed. The number of triangles is the number of indices divided by three.
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: The PER_PART and PER_FACE bindings specify 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
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, Open Inventor assumes you provided 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.
Textures are applied as described for the
Draws triangles based on the current coordinates, normals, materials, drawing style, and so on.
Computes the bounding box that encloses all vertices of the face set with the current transformation applied to them. Sets the center to the average of the coordinates of all vertices.
If any triangle callbacks are registered with the action, they will be invoked for each successive triangle generated from each triangle in the set.
