Volumetric Displays

my exploration on the contemporary creations of volumetric displays...

his blog mitxela.com/candle might better explain this, but observations from my end:

a very clever design, how he managed to fix the axle and rotate the motor instead.
used a LiR2450 rechargeable coin cell to power the motor, RP2040 Tiny and the 8x10 LED matrix.
instead of rasterising an .obj file to voxels, he used an intersection technique in Blender and exported the voxel data.

i have made several export scripts and visualisers for this sort of voxel exports. the site is live and code is up on github, do check if you're making one.

James' version of the volumetric display is the most robust so far from the makers around.

two versions:
- one with 128x64 LED matrix (two 128x64 back and forth).
- another with 128x128 (two 128x64 side by side).

the code includes three main programs:
1. vortex – runs on Raspberry Pi and lights up the actual matrix.
2. virtex – an OpenGL program which simulates the actual display.
3. viewer – helps import 3D objects and images to memory buffer read by Virtex and Vortex.
his Mastodon thread has more content on volumetric displays than anywhere else on the internet.
a very clear explanation on how to get a uniform voxel density across the volume.

The very first time i came across the term "a volumetric display" was when Voxon Photonics happened to my feed. i was amazed; it really felt magical to see how people were playing games in true 3D. i think they are the pioneers of this tech, though i've found a very old research paper on creating swept volumetric displays (i'll attach the link soon, will have to go crazy finding it in bookmarks).
