Mesa 3d or proprietary gl library #27

Closed alabd14313 closed 9 years ago

alabd14313 commented 9 years ago

Hi! Do you use mesa 3d or nvidia-gl or etc? Mesa implemented openGL 4.2. How you implement this pipeline?

Another quick question: Can I use this pipeline with my python 3 compiled panda3d? and can I use this pipeline with c++ (like panda3d c++ api)?

I think panda supports mesa, I'm not sure what feature set mesa supports tho. If mesa supports ARB_image_load_store then the pipeline is most likely to run there, otherwise not.

I'm not sure what you mean with nvidia-gl. The pipeline uses the OpenGL backend provided by panda3d.

You should be able to use the refactored pipeline with Python 3, If any problems occur, please let me know so I can fix those isuses. The old pipeline (the version from the master branch) is not compatible with python 3.

You can also use the pipeline from c++, however, since a big part of the pipeline is python, you would have to store the render pipeline in a PyObject and call methods like add_light on that PyObject. The lighting system itself is written in C++ tho, so you can store lights as c++ objects in your code.

Cheers, tobspr

You should use the proprietary driver from NVIDIA. The Mesa drivers are slowly catching up in their OpenGL 4 support, but they're not there yet. They're getting pretty close, though, so maybe in the near future.

Thanks for your attention! I prefer mesa 3d even with it's slow development because of FOSS philosophy and because of I'm a CS student and I don't like proprietary closed source apps!!! Please see this site: http://mesamatrix.net/ Panda3d 1.9 works fine in linux and mesa. I will try to test this pipeline and eventually it haven't any problem if have written in panda 3d openGL.

As you see on that matrix, compute shaders (ARB_compute_shader) are not currently supported. They're working on it, though, so maybe soon!
