This Rhino 5.0 module allows one to tile geometry over a freeform spline surface S(u, v). Geometry will be tiled UTiles times in the surface u direction, VTiles times in the surface v direction and WTiles times in the surface normal direction. In addition, along the surface normal the tiles will span from ZMin to ZMax, where Z = 0 is on the surface. To ensure a water-tight result, the tile better be precisely periodic. That is, the tile's XMin boundary must be the same as XMax boundary (and same for Y and Z). The tile can be one of:
• A 3D polygonal mesh tile, in which case the mesh is tiled over S(u, v). Result is a 3D polygonal mesh located over S(u, v).
• A set of freeform spline surfaces, in which case the surfaces are tiled over S(u, v). Result is a set of freeform spline surfaces precisely located over S(u, v) while continuity is preseved. This quality result is achieved using spline surface-trivariate composition but result will be of a higher degree.
This is the first release. Please use it "as is", as it comes for free and with no warranties whatsoever. There is a lot of effort in developing these algorithms, so please give credit where credit is due.
