This video shows a real time 3D triangle rendered on a 32×32 RGB LED matrix panel (Adafruit) with a Raspberry Pi 3 (hardware) and GeeXLab (software). Rendering is done with OpenGL 2.1 on Raspbian Jessie.
32×32 RGB LED Matrix Panel – 6mm pitch: Bring a little bit of Times Square into your home with this sweet 32 x 32 square RGB LED matrix panel. These panels are normally used to make video walls, here in New York we see them on the sides of busses and bus stops, to display animations or short video clips. We thought they looked really cool so we picked up a few boxes of them from a factory. They have 1024 bright RGB LEDs arranged in a 32×32 grid on the front on a 6mm grid. On the back there is a PCB with a set of dual IDC connectors (one input, one output: in theory you can chain these together) and 12 16-bit latches that allow you to drive the display with a 1:16 scan rate.
