optimizing & de-duplicating geometry in GLTF files

optimize GLTF file

This optimizes a GLTF file that was exported by blender (or similar) by de-duplicating buffer views (i.e. chunks of bytes) that are equal and removing redundant accessors.

For example, 100 cubes of different scales/materials/rotations/etc should all end up using a single BufferGeometry in ThreeJS, which isn't the case with current GLTF exporters in Blender and parsers for ThreeJS.

In scenes with a lot of instancing, it can dramatically reduce total file size as well as render performance. In one test scene:

Before: 4.8MB file size, 832 THREE.Geometry instances across 832 THREE.Mesh objects
After: 661KB file size, 13 THREE.Geometry instances across 832 THREE.Mesh objects

A collection of WebGL and WebGPU frameworks and libraries

A non-exhaustive list of WebGL and WebGPU frameworks and libraries. It is mostly for learning purposes as some of the libraries listed are wip/outdated/not maintained anymore.

# Hello, and welcome to makefile basics.

# You will learn why `make` is so great, and why, despite its "weird" syntax,
# it is actually a highly expressive, efficient, and powerful way to build
# programs.

# Once you're done here, go to

# to learn SOOOO much more.

Rabbit.MQ + Node.js Notes

Abstraction Suggestions

Summary: use good/established messaging patterns like Enterprise Integration Patterns. Don't make up your own. Don't expose transport implementation details to your application.

Broker

As much as possible, I prefer to hide Rabbit's implementation details from my application. In .Net we have a Broker abstraction that can communicate through a lot of different transports (rabbit just happens to be our preferred one). The broker allows us to expose a very simple API which is basically:

  • publish
  • request
  • start/stop subscription
