meshoptimizer VS Open3D

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

I was going to file a bug about another issue, but I have to download the development version. This is why I want this solved quickly. None of the links seem to work: https://github.com/isl-org/Open3D/issues/6259

Open3D (JSON, LOG, PLY) 1

There's also Open3D (O3D) the point cloud library... http://www.open3d.org/

would this help?

http://www.open3d.org/ seems like a good choice. Is there anything better I'm missing?

Open3D v0.13.0 http://www.open3d.org/

Sweet work! If you are interested in 3D reconstruction, have a look at http://www.open3d.org.

I normally use Open3D (http://www.open3d.org/) for point cloud visualization, which besides free view also provides an interface for rendering. For the rotation effect, place your object in the world origin, and the camera at a fixed world position looking towards the object. For every desired angle, rotate your object around the required axis by that angle and render the view. Then combine to a gif or video for presentations.
