I have made a program that turns 2d images into 48x48, tricolor images, and then writes instructions on how to recreate them inside opencomputer's hologram projector. I wanted to move on to doing 3d images, using the full capabilities of the projector, but I'm not great at voxel art. If someone could point me to a website, forum, whatever, that has files which are 3 dimensional voxel arrays which I can use with my program to recreate as holograms, I would be very grateful. Thanks in advance!
