Build Status

Pop Engine

Features

Not comprehensive, and in no particular order. But things this engine can do

• Build small enough for app-clips (down to 2mb, +2mb for poph264 and +2mb for PopCameraDevice - need to remove these dependencies)
• Swift integration (mac & ios apps now expected to boot from swift @main classes)
• Runs on pi's
• Runs on Nvidia Jetsons
• Runs in docker
• import and export handler (preprocessor) to allow modules in native ios/mac JavascriptCore
• Once ran v8, (mac, windows and linux) but currently dropped as it's a nightmare to build v8 and impossible to find static libs for every platform
• Runs chakra-core on windows (& hololens, at one time) for native JS
• Once ran charkracore (from repository) on mac and ios as proof of concept
• Same JS (via Pop.) for webxr, openxr etc
• Abstracted rendering system. Serialised "Render commands" (SetRenderTarget,Draw etc) to aid network rendering, debugging etc - can even render same commands to metal and GL at the same time)
• Heavily async internally (lots of work farmed to c++ threads)
• Uses native GUI apis where possible (interfaces with HTML, swift, win32)
• Websocket servers & clients (bar web which only has WS clients), UDP, TCP sockets, HTTP servers, clients etc
• Explicit native image handling/interfacing for seamless bytes<->canvas<->rendering integrations

Build Notes

• Raspberry PI/Linux via visual studio

  • https://docs.microsoft.com/en-us/cpp/linux/connect-to-your-remote-linux-computer?view=vs-2019
  • sudo apt install openssh-server
  • sudo service ssh start
  • sudo systemctl enable ssh
  • Setup Visual studio via Tools->Options->Cross Platform->Connections
  • Magic_enum requires gcc9, jetson (and pi?) have gcc --version 7
    • sudo apt-get install gcc-9 doesnt exist yet
    • https://askubuntu.com/a/1140203
    • sudo apt-get install software-properties-common
    • sudo add-apt-repository ppa:jonathonf/gcc-9.0
    • sudo apt-get install gcc-9 g++-9
    • make gcc/g++ default to new version sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-9 60 --slave /usr/bin/g++ g++ /usr/bin/g++-9

• Osx

  • Install engine package dependencies (PopH264, PopCameraDevice, PopVision) via our published packages via npm (with the github repository)
  • Modify PopEngine.Package/.npmrc to change YOUR_AUTH_TOKEN into your github auth token with access to NewChromantics packages (ask [email protected]).
  • Do not commit this token. Github will spot it and revoke the token for security.
  • run cd PopEngine.Package && npm install to download the packages
  • run ln -s node_modules/@newchromantics/ ../Libs to make a symbolic link to the packages in the correct (/Libs/) directory

• Linux(raspi buster) via VirtualBox + VSCode

  • Install remote-ssh into vscode
  • Make sure SSH-Server is installed (default installed in raspbi buster) Install ssh-server on linux; sudo apt-get install openssh-server
  • Enable SSH server (default disabled) sudo raspi-config and enable from interface options
  • Connect with default [email protected] by pressing F1 and typing Remote-ssh: connect to host (lovely ux)
  • Updated GCC if gcc --version is less than 9 (See above). (Raspian currently default 8)
    • gr: the jonathonf routine isn't working.
    • sudo apt-install g++-9 installs... clang-9 but not g++-9. There doesn't seem to be gcc-9 still.

GitHub Actions Notes

If you are getting git checkout errors on self hosted runners ssh in and manually delete the repo then restart the workflow
