Here is my buildWall() method: carreauSize is the size of my texture (n*n) (could be improved to (n*m) p1 and p2 are corner point (opposite)

If you don't have money to buy such a program, you may want to download Blender, a fairly decent freeware modeling program. Or you could create a Box object and scale it to an appropriate size. Creating geometry by typing in a lot of datapoints is very painful and I would not recommend it.
