Sorry, but I'm asking for a complete and running code.
I know the several methods how to write such a code, but I'm really busy in our current (very big) adventure project.
So, if someone has such a code, please post it here. I can't imagine that no one has such a common code and I have to reinvent the wheel ?!?
I know that jcl has a code for that on his list to add to the default gs-shaders, but he hasn't added it yet.
Regards,
Pegamode.
