meshoptimizer VS tinygltf

1) I used meshoptimizer to simplify meshes and building meshlets. But to combine these meshlets (for more efficient simplifying) I built a graph with weights and partition it. In this weight some metrics are included: the shared border length of a pair of meshlets, their facing direction and other similar metrics. The next step is to simplify these groups of meshlets (fixate borders for each of them and simplify meshlets within the group). So, you can make dependencies of newly generated meshlets on the initial ones.

Here are some amazing tools for compressing GLTFs: https://github.com/zeux/meshoptimizer/blob/master/gltf/README.md

I've also had good results with this tool: https://github.com/zeux/meshoptimizer/blob/master/gltf/README.md and kt2tdecoder + meshopt_decoder

Implemented Mesh LOD system. LOD selection is done completely on GPU. I generate LODs using meshoptimizer.

Maybe Meshoptimizer can be useful?

Added NVidia mesh shader pipeline support, with old pipeline still supported on top. Meshlets are generated using meshoptimizer.

I've used the "Simplification" operation of meshoptimizer to simplify 3D model geometry: https://github.com/zeux/meshoptimizer

I call meshopt_simplify(). It uses a quadric error metric based mesh simplification of some sort. I haven't really looked into the details of how it works, but the code (with some comments referencing papers) can be found here: https://github.com/zeux/meshoptimizer/blob/master/src/simplifier.cpp

hi! i am building a game engine with c and raylib and i want to use this library for optimizing meshes : https://github.com/zeux/meshoptimizer

Have you considered this? https://github.com/zeux/meshoptimizer

Hey. I am trying to adopt gLTF 2.0 in my "engine". I am using tinyGLTF library. I have troubles with reconstruction of tangent normals. When I try to convert sampled normal vNt from normal map into world space by multiplying by TBN matrix I get a wrong result:

Here's an example of a recently patched remote code execution vulnerability in a library that parses gltf: https://github.com/syoyo/tinygltf/issues/368

I'm playing around with my own OpenGL rendering engine and I'm encountering an error when trying to include the tiny_gltf.h library found here. Every definition in the tiny_gltf.h header is throwing an error similar to the following:

I searched for tinygltf in Google and found https://github.com/syoyo/tinygltf. I'm on mobile and didn't see the download link, but I switched the browser to desktop mode and there the green Code button is visible. And uf you click on it, you see the Download Zip link.

If so, what if I'm using tiny_gltf, I don't get vectors of vertices so I can't sort them different. As far as I know.

Or, alternatively https://github.com/syoyo/tinygltf

If you want a file format that is much more featureful and much more shippable, look at https://github.com/syoyo/tinygltf
