GA::kit

GA::kit is G&A's in-house C++ application framework for building interactive experiences.
We use it to create anything from 2D UI prototypes to high-performance 3D immersive installations.

We designed it from scratch to be:

• fast -
  Our scenegraph lets you intuitively craft complex 3D scenes without sacrificing performance.

• flexible -
  Every app is different. We use modular components, templated classes, and helpful utilities to support iterative, agile development.

• familiar -
  As creative coders, we love the clarity and efficacy of existing toolkits like openFrameworks and Cinder.
  That's why we designed GA::kit to work as an oF addon - and a Cinder Block is on the roadmap.
  Or bring your own rendering engine - we strive to be framework agnostic.

How To Use

ofxGAkit openFrameworks addon

Currently, the simplest way to use GA::kit is through ofxGAkit openFrameworks addon.

Simply git clone --recursive the addon repo inside of your openFrameworks/addons/ directory, then use the oF Project Generator to generate a project with the addon selected.

The addon works for both Windows and Mac. Full setup instructions can be found here.

In this case, openFrameworks provides the windowing and rendering system (glfw / openGL), and automatically includes the necessary nlohmann::json and glm libraries.

Bring Your Own Backend

We aim to make GA::kit "framework agnostic". This means that we would like it to play nicely with other C++ creative coding frameworks like Cinder - or it could be used on its own by including a few supporting libraries.

The only requirements beyond C++14 are including the glm and nlohmann::json libraries, and adding an openGL windowing library, like glfw.

We could use your help:

• creating a Cinder block. Todo: Cinder block repo link
• creating a "framework-free" example project, showing how to include glm, nlohman::json and glfw

Features

• Hierarchical 3D Scenegraph with Scene, Node, and Component classes
• Innovative tween animation system with Tween, Timeline and easing functions
• Timer and Timeout classes for triggering timed callbacks
• Universal app asset management with templated ResourceCache class
• KeyEvent, MouseEvent and TouchEvent handling
• Layout utitilies to automatically align and scale to fit
• Math utilities built on glm
• JSON serialization, using nlohmann::json
• Signal-based event system, using sigslot (included)
• Universal Unique ID system, using crossguid (included)

Todo

• GLSL Shader class
• Material (shader + textures + parameters) component
• Mesh VBO component
• Cinder block
• Framework-free example using GLFW

Requirements

• C++14
• OpenGL 3+
• glm
• nlohmann::json
