Applying a 2d mesh to a 3d surface

I have a very complex 3d surface I need to apply a 2d mesh to. What I need is something like the Solidworks Wrap tool : http://www.rickyjordan.com/2009/01/the-solidworks-secret-weapon-the-wrap-tool.html

Due to the complexity of the 3d surface normal texture UV unwrapping won't work. For instance, if I want to map a O and开发者_C百科 the 3d surface has a bulge where the middle of the O should be, the O should flow around the bulge. However mapping a E to the same surface should cause the middle line on the E to flow up and over the bulge.

Any ideas of any other programs/algorithms that provide this support?

If you can render your 2D stuff to a texture, you could use projective texture mapping.
