public class SoQuadMesh extends SoNonIndexedShapeQuadrilateral mesh shape node. This shape node constructs quadrilaterals out of vertices. The vertices may be specified in the
SoVertexShape), or by the current inherited coordinates. For optimal performance, the
vertexPropertyfield is recommended.
SoQuadMeshuses the coordinates, in order, starting with
startIndex. The number of vertices in the columns and rows of the mesh are specified by the
verticesPerRowfields. (Note that these numbers are 1 greater than the number of quadrilaterals per row and per column.)
For example, an
verticesPerColumnof 3, and
verticesPerRowof 4 would use coordinates 1, 2, 3, and 4 for the first row of vertices, coordinates 5, 6, 7, and 8 for the second row, and coordinates 9, 10, 11, and 12 for the third (last) row. The result is a mesh of 3 quadrilaterals across by 2 down.
The coordinates of the mesh are transformed by the current cumulative transformation. The mesh is 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 row of the mesh. The PER_FACE binding specifies a material or normal for each quadrilateral. The _INDEXED bindings are equivalent to their non-indexed counterparts. The default material binding is OVERALL. The default normal binding is PER_VERTEX.
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.
NOTE: A quad mesh may not render or pick correctly if any of its polygons are self-intersecting or non-planar.

Draws a mesh based on the current coordinates, normals, materials, drawing style, and so on.
Computes the bounding box that encloses all vertices of the mesh 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 forming the quadrilaterals of the mesh.
