Got a little project I'd like to share.

It's a interactive portfolio book that will show off some of my works. Right now it's still in development.

Not sure why I never did it - but you can totally use my #MIDI plugin for Blender to generate a piano animation - then export it to the web (or a game engine like UE, Godot, or Bevy)

Here's an example running in #ThreeJS / React Three Fiber

You can now deploy to Needle Cloud from #stackblitz or #github without a PRO license. Just go to your team page, create a new access token and deploy with:

npx needle-cloud deploy "<path>" --token "<token>"

Checkout the Needle Cloud CLI docs: https://engine.needle.tools/docs/cloud/#deploy-from-the-cli

I've also added a bunch more facefilter examples to github: https://github.com/needle-engine/facefilter

Below is a single index.html complete example works for 2d and 3d assets

I may need to build 3D Gizmos again, so thought I put together a simple ex of all the main actions needed. Got line & plane translation with visualizers for the raw data. FromScratch raycasts + mathlib, free & portable 4 all
