# Third party libraries ## b2d_convexdecomp - Upstream: https://github.com/erincatto/Box2D/tree/master/Contributions/Utilities/ConvexDecomposition - Version: git (25615e0, 2015) with modifications - License: zlib The files were adapted to Godot by removing the dependency on b2Math (replacing it by b2Glue.h) and commenting out some verbose printf calls. Upstream code has not changed in 10 years, no need to keep track of changes. Important: Some files have Godot-made changes. They are marked with `// -- GODOT start --` and `// -- GODOT end --` comments. ## bullet - Upstream: https://github.com/bulletphysics/bullet3 - Version: git (d05ad4b, 2017) - License: zlib Files extracted from upstream source: - src/* apart from CMakeLists.txt and premake4.lua files - LICENSE.txt ## certs - Upstream: Mozilla, via https://apps.fedoraproject.org/packages/ca-certificates - Version: 2018.2.22 - License: MPL 2.0 File extracted from a recent Fedora install: /etc/pki/ca-trust/extracted/pem/tls-ca-bundle.pem (It can't be extracted directly from the package, as it's generated on the user's system.) ## cvtt - Upstream: https://github.com/elasota/cvtt - Version: 1.0.0-beta4 - License: MIT Files extracted from upstream source: - all .cpp, .h, and .txt files in ConvectionKernels/ ## enet - Upstream: http://enet.bespin.org - Version: 1.3.13 - License: MIT Files extracted from upstream source: - all .c files in the main directory (except unix.c win32.c) - the include/enet/ folder as enet/ (except unix.h win32.h) - LICENSE file Important: enet.h, host.c, protocol.c have been slightly modified to be usable by godot socket implementation and allow IPv6. Two files (godot.cpp and enet/godot.h) have been added to provide enet socket implementation using Godot classes. It is still possible to build against a system wide ENet but doing so will limit it's functionality to IPv4 only. Check the diff of enet.h, protocol.c, and host.c with the 1.3.13 tarball before the next update. ## etc2comp - Upstream: https://github.com/google/etc2comp - Version: git (9cd0f9c, 2017) - License: Apache 2.0 Files extracted from upstream source: - all .cpp and .h files in EtcLib/ - README.md, LICENSE, AUTHORS Important: Some files have Godot-made changes.
