This project revisits the code originally created for the Written Images project. There were some aspects of the code which always frustrated me that I didn’t know how to address at the time. In reworking this code, I finally figured out how to deal with large numbers of point lights in GLSL shaders as well as getting a better handle on dealing with the magnetic field itself. Previous versions used a rotation matrix to try and whip and spin the magnetic field into interesting forms. This was not an ideal solution. So I gutted the magnetism code and restructured it so that I wouldn’t need to rely on tricks. The results are quite promising.
Crystalline was made with the Cinder C++ framework.
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
