AminoGFX implementation for OpenGL / GLES2

This Fork

Rough WIP fixes and modifications:

• Windows and Linux support
  • Windows support is missing video, jpeg, etc support, since I didn't want to deal with all those libraries, etc when porting
  • Linux support is probably complete, but untested
• RPI
  • tested on RPi 3 + Zero W with fake KMS driver, on RPi 4 with dtoverlay=vc4-fkms-v3d and max_framebuffers=2
  • Builds using older DispManX code instead of newer GBM, to work with older RPi/driver
  • partial keyboard support (needs more keys mapped from linux to glfw codes)
• Functionality
  • Changed how origin works so it makes more sense
  • Added partial typescript bindings
  • Allow passing 'null' as the target of keyboard event listeners to always receive events
  • Fix texture leaking when changing source of ImageView- now updates GL texture with new data
  • Fix mouse click detection issue when using originX/Y (still ignores rotation)

aminogfx-gl

AminoGfx implementation for OpenGL 2 / OpenGL ES 2. Node.js based animation framework supporting images, texts, primitives, 3D transformations and realtime animations. Hardware accelerated video support on Raspberry Pi.

Platforms

• macOS
• Raspberry Pi

Requirements

In order to build the native components a couple of libraries and tools are needed.

• Node.js 4.x to 14.x
• There is a bug in Node.js v6.9.1 (see nodejs/node#9288; fixed in Node.js > 6.10).
• Freetype 2.7
• libpng
• libjpeg
• libswscale

macOS

• GLFW 3.3
• FFMPEG

MacPorts setup:

sudo port install glfw freetype ffmpeg

Homebrew setup:

brew install pkg-config
brew tap homebrew/versions
brew install glfw3
brew install freetype

Raspberry Pi

• libegl1-mesa-dev
• libdrm-dev
• libgbm-dev
• libfreetype6-dev
• libjpeg-dev
• libav
• libswscale-dev
• libavcodec-dev
• Raspbian (other Linux variants should work too)

Setup:

sudo rpi-update
sudo apt-get install libegl1-mesa-dev libdrm-dev libgbm-dev libfreetype6-dev libjpeg-dev libavformat-dev libswscale-dev libavcodec-dev

Installation

npm install

Build

During development you'll want to rebuild the source constantly:

npm install --build-from-source

Or use:

./rebuild.sh

Demo

node demos/circle.js

Example of all supported features are in the demos subfolder.

Troubleshooting

• node: ../src/rpi.cpp:209: void AminoGfxRPi::initEGL(): Assertion `success >= 0' failed.
  • select a screen resolution with raspi-config
