This node uses the coordinates in order, either from the state or from the vertexProperty node, to construct a quadrilateral mesh. The quads are generated in row major order, using the two field verticesPerColumn and verticesPerRow to specify the mesh. E.g. if verticesPerColumn is 3 and verticesPerRow is 2, two quads will be generated, the first one using (in order) coordinates 0, 1, 3 and 2, the second one using coordinates 2, 3, 5 and 4 (you get three rows of vertices; the first row uses vertices 0 and 1, the second row 2 and 3, and the third row 4 and 5).
Normals and materials can be bound PER_PART (per row), PER_FACE, PER_VERTEX and OVERALL. The default material binding is OVERALL. The default normal binding is PER_VERTEX.

Constructor. |
|
Destructor. |
|
Sets up initialization for data common to all instances of this class, like submitting necessary information to the Coin type system. Reimplemented from SoNonIndexedShape. |
|
Action method for the SoGLRenderAction. This is called during rendering traversals. Nodes influencing the rendering state in any way or who wants to throw geometry primitives at OpenGL overrides this method. Reimplemented from SoShape. |
|
Action method for the SoGetPrimitiveCountAction. Calculates the number of triangle, line segment and point primitives for the node and adds these to the counters of the action. Nodes influencing how geometry nodes calculates their primitive count also overrides this method to change the relevant state variables. Reimplemented from SoShape. |
|
Overloaded to return FALSE. Normals are genereted in normal cache. Reimplemented from SoVertexShape. |
|
For internal use only. Reimplemented from SoShape. |

Subclasses should overload this method to generate default normals using the SoNormalCache class. This is more effective than using SoNormalGenerator. Return TRUE if normals were generated, FALSE otherwise. Default method just returns FALSE. This method is not part of the original OIV API. Do not overload it if you intend to create a node that can be used on both Coin and OIV. Reimplemented from SoVertexShape. |

Specifies the number of vertices in each row. |
