The book, 'Patchwork Persuasion' by Joen Wolfrom is about drafting blocks. She has a section on stretching and distorting. Some of the quilts in the inspiration section using this technique appear to be 3D. Not 100% sure if this will produce the result you are looking for, but you can get a used copy for a penny + postage on amazon. The book is very informative and has lots of eye candy!

I would also look at Geta Grama's site. She has a lot of perspective quilt patterns.
