The Raspberry Pi Sense HAT is a really cool piece of hardware: it’s an all-in-one board that comes with several sensors and even a LED matrix. Let’s discover it.
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!
In 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.
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.
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!
The new Raspberry Pi 3 board comes with a new processor and higher clock speeds. Let’s benchmark it against the Raspberry Pi 2 board.
The latest GeeXLab 0.9.6.0 is available with a new support: Raspberry Pi with OpenGL desktop (OpenGL 2.1).
Don’t know what to do with the 7-inch touchscreen display you bought for your Raspberry Pi? Transform it in a clock.
Here is a ready-to-use GeeXLab demo (OpenGL ES 2.0), that displays a clock.
I received last week the official touchscreen display for the Raspberry Pi. This 7-inch display has a resolution of 800×480 pixels, 140° horizontal viewing angle and supports 10-finger touch. The latest version of Raspbian integrates all necessary drivers for full functionality. Let’s test it.
