I’m working on a top secret project for Sam Aaron of Meta-eX fame involving the Raspberry Pi, and at the same time thinking of my upcoming CodeClub lessons this term – we have a bunch of new Raspberry Pi’s to use and the kids are at the point where they want to move on from Scratch.
This is a screenshot of the same procedural landscape demo previously running on Android/OUYA running on the Raspberry Pi, with mangled texture colours and a cube added via a new livecoding repl:
Based on my previous experiments, this program uses the GPU for the Raspberry Pi (the VideoCore IV bit of the BCM2835). It’s fast, allows compositing on top of whatever else you are running at the time, and you can run it without X windows for more CPU and memory, sounds like a great graphics livecoding GPU to me!
Here’s a close up of the nice dithering on the texture – not sure yet why the colours are so different from the OUYA version, perhaps a dodgy blend mode or a PNG format reading difference:
The code is here (bit of a mess, I’m in the process of cleaning it all up). You can build in the jni folder by calling “scons TARGET=RPI”. This is another attempt – looks like my objects are inside out:
