Within the attached include file, you could replace uv_vertex with your
computed position.

The top macro is UVMeshable, first parameter is an object, just
ignore/remove it
The two others are the resolutions... you can simplify too for your
usage (getting ride of uv_min & uv_max).

mesh{
UVMeshable...

then you insert the uv_mapped texture (and I already provided some code
for that part in this thread)

et voila.
