| [ACTC](https://sourceforge.net/projects/actc) | ACTC converts independent triangles into triangle strips or fans. |
| [ANN](https://www.cs.umd.edu/~mount/ANN/) | ANN is a library written in C++, which supports data structures and algorithms for both exact and approximate nearest neighbor searching in arbitrarily high dimensions. |
| [Brotli](https://github.com/google/brotli) | Brotli is a generic-purpose lossless compression algorithm that compresses data using a combination of a modern variant of the LZ77 algorithm, Huffman coding and 2nd order context modeling, with a compression ratio comparable to the best currently available general-purpose compression methods. It is similar in speed with deflate but offers more dense compression. The specification of the Brotli Compressed Data Format is defined in RFC 7932. |
| [c-ares](https://c-ares.haxx.se) | c-ares is a C library for asynchronous DNS requests (including name resolves) |
| [Check](https://libcheck.github.io/check/) | Check is a unit testing framework for C. It features a simple interface for defining unit tests, putting little in the way of the developer. Tests are run in a separate address space, so both assertion failures and code errors that cause segmentation faults or other signals can be caught. Test results are reportable in the following: Subunit, TAP, XML, and a generic logging format. |
