Please describe your issue below:

I’m having some difficulty with GLES 3.2 development. Things I’ve compiled that are OpenGL based, behave as if they are (I believe, no proof as of yet) using the CPU based Mesa renderer. (librealsense, Open3D, OpenSceneGraph). Of the three OpenSceneGraph has a GLES3 build option, but the performance still makes me wonder.

First, is there an easier way to know when an application is using the Mali chip for rendering?

Second, what API’s and/or frameworks support and work on the Edge2 with Ubuntu? Something slightly higher level than EGL and GLES? I’ve tried GLFW for setting up my window but having issues getting the 3.2 context. Still not sure how to debug.

Thank you!

Hello @bradcolbert

About OpenGLES, maybe you can find some example source code here.

@numbqq thank you.

I did look there and it is helpful but I found a really good example in mesa-demos that kind of put’s together all of the pieces.
