lace

Polygonal mesh library developed at Body Labs.

The library is in active maintenance, and the goals are compatible with that:

• Keep the library working in current versions of Python and other tools.
• Make bug fixes.
• Provide API stability and backward compatibility with the upstream version.
• Respond to community contributions.

The eventual goal is to perform a rewrite of the loader and core mesh functionality with quad support as part of a "lace-core" project and consider how to handle the extensive mesh manipulation functions which remain.

Acknowledgements

This library was refactored from legacy code at Body Labs by Alex Weiss, with portions by Eric Rachlin, Paul Melnikow, Victor Alvarez, and others. It was extracted from the Body Labs codebase and open-sourced by Guillaume Marceau. In 2018 it was forked by Paul Melnikow and published as metabolace. Thanks to a repository and package transfer from Body Labs, the fork has been merged back into the original.
