For the record, this is one idiot techbro *assumption* without a shred of research.

It’s a false assumption, for anyone who actually reads research or does their homework.

Shame on Khronos for propagating random techbro opinion, but we should expect nothing less.

GLTF 2.0 Is Broken - So I Made A Better 3D File-Format!

youtu.be/cgY-faQrv78

A 10-minute video presentation about how I created a prototype file-format simpler and more capable than glTF!

It's called STF - Scene Transfer Format.
Designed to easily support rapidly prototyping extensions to represent fully featured VR & V-Tubing avatars!

I will not join Siggraph this year.

But ... some of my work will.
Blender is a major open source software to create glTF assets, using Blender-glTF-IO addon, shipped with Blender.

I maintain & develop it.

In slight need of spec/language lawyers: Reading this line ( registry.khronos.org/OpenCL/sp), do you think:
A: that the minimum allocation of the max mem allocation flag is 1:4?
B: that the max allocation must be max(min(1024 × 1024 × 1024, 1/4th of CL_DEVICE_GLOBAL_MEM_SIZE), 32 × 1024 × 1024)

in other words, given a 16GB card, should the maximum allocation be 4GB, or should the minimum of the max allocation be 4GB?

#Introduction / #NewHere: My wandering career has led me to Google, where I own #modelviewer, your #opensource #web library to put #3D on your page with just a line of HTML, in photorealistic #PBR.

I also work standards on #glTF with #Khronos, and long ago with #3MF.

My side project is #Manifold, an open source #geometry kernel which I believe is the first to guarantee manifold mesh output. Test it out at manifoldcad.org/

manifoldcad.orgManifoldCADFast, reliable, parametric solid modeling web app. Programmatic 3D design with JavaScript, inspired by and improving upon OpenSCAD & JSCAD. Demonstrates a new GPU-parallel, open-source geometry kernel: Manifold.

Summary of my anger toward #Khronos software management in one command line:

% pacman -Ql glslang | grep -oE '[^/]+\.(so|a)$'
libGenericCodeGen.a
libHLSL.a
libHLSL.so
libMachineIndependent.a
libOGLCompiler.a
libOSDependent.a

libSPVRemapper.a
libSPVRemapper.so
libglslang-default-resource-limits.a
libglslang-default-resource-limits.so
libglslang.a
libglslang.so

Don't expect pc files associated. Some are even just mandatory stub libs.

Libs detection is overall a nightmare.

Continued thread

Learn how to create a 3D model from scratch, UV wrap it, and export it.

This goes a bit further than the donut tutorial and forces you to create a new structure, texture, unique map and actually put it in a usable format - which can be tricky.

 #Blender has support for GLTF, which everyone should be using, given its universal compatibility and direct support by #Khronos Group.

Basic tutorials are all over, but few touch on everything. Try this:

#introduction

I'm a #Linux graphics driver developer who works across the stack. I've done a bit of kernel hacking but am mostly focused on #Mesa3D userspace drivers and the #Vulkan API. I'm also part of the #Khronos working group that defines the Vulkan API.

I'm currently developing a brand new open-source Vulkan driver for NVIDIA hardware called NVK: collabora.com/news-and-blog/ne

I post about my work and various other graphics topics and try to help demystify graphics hardware and drivers.
