Rendering real time 3D on RGB LED Matrix Panel with GeeXLab

First article: Adafruit 32×32 RGB LED Matrix Panel unboxing

I’m starting a series of articles about how to render real time 2D/3D graphics on RGB LED matrix panels with a Raspberry Pi. Even if the resolution of graphics is very low (32×32 pixels for a 32×32 LED display), drawing 3D stuff on that kind of display is very cool!

Here the second article (first one is HERE) about how to render real time 3D stuff on a RGB LED matrix panel with a Raspberry Pi. In this article, we’ll look at the hardware interface between the Raspberry Pi and the RGB LED matrix display: the RGB Matrix HAT.

n previous articles (HERE and HERE), we have talked about the RGB LED matrix panel as well as the RGB Matrix HAT which is the hardware interface between the LED panel and the Raspberry Pi. Today we will cover how to draw simple graphics on the LED panel.

Someone just released a 32x32 pixel (!) demo at Shadertoy: Rainbow Dash (converted to GeeXLab)
Could you try?

Last article: Rendering Real Time 3D Graphics on a 32×32 RGB LED Matrix Panel with a Raspberry Pi and GeeXLab

In the previous article, I explained how to control the color of a particular LED of the RGB LED matrix panel. Thanks to that knowledge, you can draw simple graphics: points, circles, lines and so on. But how can we easily draw a rotating triangle? Or a mesh like a torus? Or any 3D scene? Answer in this article!
