DVsurf_plot creates a 3D or 2D mesh whose height at each point is proportional to the scalar data value at that node location in the original field. 2D input produces a 3D mesh. 1D input produces a 2D output.
The input is a reference to a field of any mesh type and any Node_Data. The field's mesh should have nspace=1 or 2. However, no checking is done to enforce this restriction. The Node_Data must contain at least one scalar component.
An integer. Sets which of the input's data components to use to set the mesh height.
A float. Used to scale the height (scale*component values).
A float. Raises or lowers the resulting mesh with respect to the input mesh so that both are visible at the same time.
The output is a reference to a merged group made up of the new object out_grid, which is a mesh of the same type as the input mesh, with nspace+1, whose coordinate values represent the projected, scaled, and offset surface, plus a reference to the original &in field.
