I wrote a quick Lisp to map an image onto a ... "sphere". Sometime in the (near?) future I will try to improve it, for the moment the image resolution is poor. I used a 3d mesh and AutoCAD limits its dimensions do 256x256.
If someone wants to play with the lisp I wrote, draw a 2d shape starting from point 100,0,0 to right. Use a solid hatch on the closed shapes, enter the PLAN command, and maybe do a zoom to "extents". Start the lisp by typing "Miki" and... wait. On my computer it took almost 2 minutes to create the model.
Have fun!
