Haven't shown much about the 3D viewer I've made for Needle so far.

It's gotten really good – if you're working with #glTF and want to understand what's going on in your files, then it's quite likely helpful!

It shows everything – meshes, materials, textures, the JSON data, hierarchy, validation, ...

...in probably the highest information density UI I made so far 😅

I published a small collection of KTX2 sample textures. KTX2 textures used in glTF models are simpler — 2D textures and Basis Universal — but KTX2 has more advanced features:

- 1D, 2D, 3D, array, and cubemap textures
- float16 and float32 “HDR” textures
- ASTC, ETC1/2, BC6H, BC7 and other GPU formats
- wide gamut primaries including P3 and BT2020
- …

I compiled samples for many of these, and expect to add more:

What's special here is that we included auto-generated USD files, and that these can be viewed both natively on the web (through Autodesk's USD-for-web) and in QuickLook / visionOS.

Hopefully this helps to improve the status quo of going back and forth between glTF and USD.

glTF assets can be filtered by file features – thanks @donmccurdy for glTF-transform, as always!

This is very helpful for both developers implementing and testing glTF, and designers trying out which features their viewer of choice supports.

Big news for glTF and USD!
I'm very happy to announce: Asset Explorer

A web app that will help to bridge the gaps between glTF and OpenUSD.

@pixelpartner I think this may interest you especially :)

We're starting to put our  
Unity - glTF - three.js - USDZ bridge out into the wild. That means you can create interactive apps in Unity/Blender, and they work as well on iOS AR in USDZ format.

Here's a musical instrument I made, and you can play this live at https://engine.needle.tools/samples/?open=1#musical-instrument, including iOS QuickLook :)

@herbst plop! 

These past few weeks I’ve been working on implementing glTF KHR_animation_pointer in glTFast for @unity. Great to see this format evolve with even more useful capabilities! https://github.com/atteneder/glTFast/pull/596

Thanks to @tteneder for the great library and @herbst for the test assets! #gltf #madewithunity
