Third party libraries

Please keep categories (## level) listed alphabetically and matching their respective folder names. Use two empty lines to separate categories for readability.

brotli

Files extracted from upstream source:

  • common/, dec/ and include/ folders
  • LICENSE

bullet

Files extracted from upstream source:

  • src/* apart from CMakeLists.txt and premake4.lua files
  • LICENSE.txt, and VERSION as VERSION.txt

Includes some patches in the patches folder which have been sent upstream.

certs

cvtt

Files extracted from upstream source:

  • all .cpp, .h, and .txt files in ConvectionKernels/

embree

Files extracted from upstream:

  • All cpp files listed in modules/raycast/godot_update_embree.py
  • All header files in the directories listed in modules/raycast/godot_update_embree.py

The modules/raycast/godot_update_embree.py script can be used to pull the relevant files from the latest Embree release and apply some automatic changes.

Some changes have been made in order to remove exceptions and fix minor build errors. They are marked with // -- GODOT start -- and // -- GODOT end -- comments. Apply the patches in the patches/ folder when syncing on newer upstream commits.

enet

  • Upstream: http://enet.bespin.org
  • Version: 1.3.17 (e0e7045b7e056b454b5093cb34df49dc4cee0bee, 2020)
  • 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's socket implementation and allow IPv6 and DTLS. Apply the patches in the patches/ folder when syncing on newer upstream commits.

Three files (godot.cpp, enet/godot.h, enet/godot_ext.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 its functionality to IPv4 only.

etc2comp

Files extracted from upstream source:

  • all .cpp and .h files in EtcLib/
  • README.md, LICENSE, AUTHORS

Important: Some files have Godot-made changes. They are marked with // -- GODOT start -- and // -- GODOT end -- comments.
