Abstract: This project introduces a true three-dimensional (3D) volumetric display designed to render real spatial graphics in physical space without needing any 3D glasses, optical tricks, or moving projectors. At its core, the setup uses a self-supporting NxNxN matrix of light-emitting diodes (LEDs) arranged cleanly across X, Y and Z axes. To keep the pin count low and the wiring simple, all anodes sharing the same vertical column are tied together, while the cathodes in each horizontal slice form individual layer planes. The system relies on a high-speed microcontroller driving a dedicated transistor switching array to control each cathode plane. This low-side switching setup fixes common display glitches like cross-talk, phantom lighting, and sudden drops in brightness. On the software side, an interrupt-driven timer and a dual-buffered memory pipeline handle the rendering logic. The processor rapidly sweeps through the display layer by layer at over 60 Hz, pushing matching 2D voxel patterns to the columns for each slice. Thanks to persistence of vision, our eyes blend these fast individual slices into a sharp, continuous 3D image. It’s a clean, affordable, and scalable display system built for real-world applications like 3D medical visualization, air traffic spatial radar, and hands-on CAD prototyping.
