Raspberry PI Zero W OpenGL support

Thu May 18, 2017 8:46 am

Hello everybody!

I am thinking to buy a Rapberry PI Zero W to build a 7" wireless LCD.
The software connects through a wireless network to a remote server, receives some data, and shows it up as a nice OpenGL rendered screen with several very simple animations.
I did not find (until now) any explicit information about OpenGL support on Raspberry PI Zero (W). That means "of course it is supported" or "of course it is NOT supported"? Can anybody share a link with some infos?

Thank you all for your time!!

in this release we are shipping an experimental OpenGL driver for the desktop which uses the GPU to provide hardware acceleration. This is turned off by default – if you want to enable it, you can find it in the command-line version of raspi-config, under Advanced Options->GL Driver. Due to memory requirements, this will not work on Pi 1 or Pi Zero boards – it is solely for Pi 2. (raspi-config will only allow it to be enabled on a Pi 2; be warned that if you enable it on a Pi 2 and then move that SD card into a Pi 1 or Pi Zero, the Pi will not boot.)

Pi0 and Pi1 have OpenGLES support through the firmware. They don't have full OpenGL support.

Raspberry Pi seems to support OpenGL ES 2.0

This talks about the desktop, I do not need it because it will be a screen without user interaction.
