I have tried several formulas to create an "unproject" function (to create a raycast and pick objects in 3D Space from 2D Screen coordinates) ... but without any success ...

Any idea ?

Not sure if this command is there, but have you tried gluUnproject?

Ouch. It's tier 1.

Then, you could try and rip off GLM's unproject function, which looks like this:



That's some work to convert it to BASIC.
Not sure if it can work for you either.

Best option is if Paul could speak out here.

I've added commands to convert between screen coordinates and 3D coordinates for the next version.

Kamac : Thanks but i have already tried to convert the original function without a real success

Paul : Great news if you add this and Animated models support it will rocks (and the shaders problem fix on 1082b)
