Hello friends. How to display 2D Image to the camera?
I'am trying to make a Joystick

I'd recommend the blitting functions of the FrameBuffer:

I hope this helps

Thank you, its working, i didn't have the perfect texture though 

Hello welcome!

Thanks for your answers. So far nothing very important to bring up. I'm just starting off the bench  and testing the lib.

I tried to modify the test case to something similar as what I had but it seems to be working fine...

I tried to look again at my own situation too but it seems fine now... 
I think I just made a mistake myself along the way
Sorry for bringing this up, I guess it was an error on my side after all
I think I forgot to set the intensities for some lights and they showed the wrong color (white by default...)

I'll report back if there was something fishy going on still but I suppose it is not the case; so... case closed for now

I made this test case, but I fail to see an issue with it:

                }

            }

    }
}



Do you have a test case that shows this problem?

Thank you!

I'll have a look...

As Aero said, it's not a problem. The stuff in the util-package is decoupled from the engine, everything that is done in there can be done with the means provided by the public interfaces.

Thanks.

I'm thinking adding some more ExtendedPrimitives as Polyhedron shapes. But regarding your license this is not possible.

You could always implement such extension of general primitive Object3D's (in a new seperate class) yourself (and share them here for others)
