Next gig is up in 2 weeks already! I'll once again using @cables_gl #cablesGL for live rendered visuals. Control via repurposed game controller works fine on MacOS which is a real treat (and surprise)

Painthead. https://davideprati.com/demo/painthead/ drawing application developed with #threejs #webgl #shaders . It uses 3d meshes as a paint brush and an ortographic camera.

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
