How could you further manipulate this into a half-pipe? Like a Spanish roof tile or a skateboard 'half-pipe'? Also, is there a way to use an alpha to poke a hole in it? So you could make an arched church window opening through it? Or a tower window?
Thanks again for this great little idea. I wonder about a couple of things: how would you create a hollow pipe with a flat side? Like the letter 'D' or a quonsett hut. Also, how can the parametric mesh be made into a polymesh with good topology that will allow 'Reconstruct SubDivide' ?
one way to make the tile would be to have just a single sided curved surface, store a morph target, then offset it or move it with the deformation palette, then use the morph target create difference and you should have a fully thick double sided tile.
