Truly impressive endeavour! I would definitely love to contribute, thanks HN for showing this up this morning! Rust + architectural models + wgpu is a great combo!
I am still in the mid-early learning phase of Rust, but it's where I'm putting my learning juices in... and at this point I can consider myself a professional architectural 3D modeller (https://www.myminifactory.com/users/TheLazyForger).
Would be happy to contribute (in fact I opened a couple of issues right now), is there a Discord or equivalent? I couldn't seem to find it on the github readme.
