HoloVox is an 8x8x8 LED Voxel Display designed, built and programmed by me. It runs on an Arduino Micro and uses an 8-bit Shiftregister and 16 AND-gates to control the 512 LEDs of the Display.
The software is capable of rasterizing lines in three dimensions and has an API to render simple wireframe models that can be moved, scaled and rotated.
