Version 1.0

Changing light path with two mirrors.(hardware is not easy to make by hand but soft algorithm will be much simple)

Version 2.0

Rotating mirror with three surrouding led screen driven by Rust, rp2020 and pio.

Software ready by rust's rp-hal, simulated by rust's plotters and rust's geo(https://hikaricai.github.io/vdrm/).

showing square pillar

Version 3.0
Working in progress, just replace the spinning mirror with aska3d's ASKA3D-Plate, so the volumetric image will be show in midair and become touchable.

ASKA3D-Plate is too expensive so I repalce it with retro reflector(3m 4090).

Acrylic board was distorted when spinning, so the image shown in midair was also distorted seriously.
