As preparation for an upcoming hardware-intensive project involving an 8x8x8 LED cube display, We want a way to preview the behavior of the display remotely. Enter
voxel-preview: like the intended physical display, the rendered cube listens over UDP for OSC packets and updates the voxels accordingly.
voxel-preview can be downloaded, built, and run with
$ git clone https://github.com/ambuc/voxel-preview.git
$ cd voxel-preview
$ cargo build
$ cargo run
At this point, an OpenGL window will pop up and show a slowly-revolving rainbow cube; the default dimensions are 8x8x8.
You can send individual packets with
voxel-preview listens on
127.0.0.1:1234 by default.
The schema is:
// port x y z r g b
send_osc 1234 /0/2/4 0.0 0.5 1.0
z are the xyz coordinates of the voxel to color, and
b are the rgb coordinates thereof.
voxel-preview will drop malformed packets within reason (
r > 1.0, for example), but it’s not that smart.
This isn’t so much a project as a tool. We aim to write a controller which interfaces nicely with something like TouchOSC, which will ultimately serve as a sort of platform for a series of abstract 3D games / toys / visualizations over the coming weeks or months.
