[Gambas-user] [Gambas3] The static method Gl.SelectBuffer

[laurent bernabe]

Hello,

I've finally managed to do a selection of my 3 cubes.
I've joined the my MMain module and my ColouredCube source file. (They need
the gb.sdl, gb.opengl and gb.opengl.glu components).

I think I'll post another source if I manage to do picking on a single cube
(And I think I will manage).

Thanks again for your help :)

Regards

Laurent Bernabé
