This plug-in attempts to emulate the functionality of the built-in surface constraint in Autodesk Softimage. But while the surface constraint works only with NURBS surfaces, this one works with polygonal meshes.
Here it is in action:
The only requirement for this to work is that the constraining geometry should have a texture map. The position of the constrained object is determined by the position of the UV coordinates of the texture map on the constraining surface.
Please note that this constraint does not work with live subdivisions. If the constraining mesh is subdivided using the Plus key, the constrained object will continue to follow the hull.
