bullet

• Upstream: https://github.com/bulletphysics/bullet3
• Version: 2.89 (830f0a9565, 2019)
• License: zlib

Files extracted from upstream source:

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

certs

• Upstream: Mozilla, via https://github.com/bagder/ca-bundle
• Version: git (4d3fe6683f, 2024), generated from mozilla-release changeset b8ea234254

cvtt

• Upstream: https://github.com/elasota/cvtt
• Version: 1.0.0-beta4 (cc8472a04b, 2018)
• License: MIT

Files extracted from upstream source:

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

embree

• Upstream: https://github.com/lighttransport/embree-aarch64
• Version: 3.12.1 (6ef362f99a, 2020)
• License: Apache 2.0

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.pyscript can be used to pull the relevant files from the latest Embree-aarch64 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 (e0e7045b7e, 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.
