Rendering Real Time 3D Graphics on a 32×32 RGB LED Matrix Panel with a Raspberry Pi and GeeXLab (**Updated**)
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!

The wizard behind Shadertoy has struk once again with this beautiful demo showing an animated snail.
La Calanque, Heavy Pixel Shader Test
La Calanque is a nice demo and a heavy pixel shader test based on this Shadertoy demo. This test is perfect to benchmark high-end graphics cards.
GLSL Hacker Stopped, GeeXLab 0.9.1.0 Released with Direct3D 12 Support
The GLSL Hacker project is now officially stopped. To make a long story short, the support of Direct3D 12 as well as the upcoming support of Vulkan (when it will be available) are the main reasons that have led to a change of name.
Adafruit 5-inch HDMI Touch Display 800×480 Tested with Raspberry Pi
Last week, I ordered this 5-inch touch display with a resolution of 800×480 pixels. I was curious to see how it would work with a Raspberry Pi and to what GLSL Hacker demos would look like.
