DVoffset "physically" deforms a mesh by the values of a 1, 2 or 3 vector component located at each node. The first element of the vector translates the node's X coordinate, the second (if present) translates the Y coordinate, and the third (again, if present) translates the Z coordinate. The magnitude of each translation is proportional to the values at the nodes multiplied by a scaling factor.
A reference to a field with Mesh and Node_Data. Its components can be a 1, 2, or 3 element vector.
An integer. Selects which of the Node_Data's components to use for the offset calculation.
A float. A scaling factor to adjust the degree of distortion caused by the vector component.
A reference to an object that is the merge of the new Grid, plus a reference to the remaining fields of the input mesh, plus a reference to the original Node_Data. Mesh --> Mesh. Mesh_Struct or Mesh_Unif or Mesh_Rect --> Mesh_Struct.
