Check out the open source auto retopology tool AutoRemesher
Tuesday, August 4, 2020 | Written by Jim Thacker
Tool developer Jeremy Hu has released AutoRemesher, an interesting new open source tool for automatic retopology to convert source meshes to clean, animation-friendly all-quad geometry.
The still-in-alpha toolset integrates with Dust3D, Hu's Epic MegaGrant award-winning open source 3D modeling software, and provides an alternative to native remeshing tools in applications like Blender.
A new alternative to Dust3D's native auto retopology tools
Hu started working on AutoRemesher as an alternative to Dust3D's native remeshing functionality, which includes tools based on the Open Meshes open source library.
In a blog post, Hu describes instant meshes as "super-fast, with high quality quads", but notes that some meshes leave "annoying holes" after remeshing.
The new toolset uses a new combination of two other open source projects: the quad extraction system libQEx and the CoMISo Constrained Mixed-Integer Solver to optimize the geometry.
Hu describes the quads created by the combination as "beautiful", although initially they can only be calculated slowly: something that he would like to improve compared to successive updates.
Already a promising alternative to Blender's native remeshing tools
Although the software is still an early alpha, it now has a basic user interface and compiled binary files so anyone interested can easily test it.
In a tweet from last week, Hu described the current build as "slower than instant meshes, but with better global edge flow".
This thread on BlenderArtists.org shows examples posted by users, including comparisons with Blender's native remeshing tools based on the open source QuadriFlow library.
Early tests suggest that processing times are quite practical and that AutoRemesher sometimes produces a better topology than QuadriFlow, although the results vary from model to model and between parts of a network.
System requirements and availability
AutoRemesher is a free standalone tool available under a GPL license. The software is still in Alpha and currently only imports OBJ files.
Binary files are available for Windows, Linux and macOS, or you can compile the software from the source code.
