Status: Hobby project, still tinkering
This is a rewrite of my older game engine.
##Instructions
- Initialize the kit submodule and checkout the master branch:
git submodule update --init --recursive
git submodule foreach --recursive git checkout master
- Get the libraries:
Vorbis, Boost, Jsoncpp, Pthread, Bullet, Sdl2, Raknet, Glew, Assimp, Freeimage, Glm, Freealut, Rapidxml, Openal, Cairomm, Ogg, Pangomm, Catch, Backward-cpp
- Build Qor with premake4:
premake4 gmake
make -j`nproc`
- siege-tools is recommended.
- Read the documentation: QorBook
##Features

- Compatible with Tiled map editor
- OpenGL ES-compatible shader-based pipeline
- Forward rendering w/ multipass lighting
- Several shaders, including tangent-space bumpmapping
- Partitioner/culling support
- Automatic VBO baking of visible areas (10x framerate in many cases)
- Mesh instance copy-on-write vertex and shader attribute modifications
- Basic instancing
- Render-to-Texture
- Thread-safe OpenGL task handler
- C++ and Python support
- Python Console
- Shared resource management

- Static mesh baking (collapse to world space and combine)
- Tracking/following w/ animation support
- Node factory supporting user classes
- Node tags
- Many 3D model formats supported
- Blender scene exporter
- Reactive Subsystems
- Communicate with/between nodes easily by sending/receiving data through named metaobject/json events
- Each node has a lightweight state machine with signal support
- User-defined events and states
- State stack
- User-defined engine states
- Async loading screens
- Input
- Multiple controllers
- Bindings specific to player profiles
- Button/switch-associated events
- Switch history for timer-based events and multiple fast press events
- Activation thresholds
- Animation (code moved to kit)
- Timer-based keyframes
- Interpolation/Easing
- Callback scheduling
- Music and 3D Sound
- Powered by OpenAL
- Wav and Ogg support
- Thread-safe
- Cairo 2D primitives w/ Render-To-Texture
- Pango Font and Text Rendering
- Headless mode for dedicated servers and unit testing
More features will be listed as I add them...
##Partial/WIP Features
- Level-of-detail
- Particle systems (rewriting this atm)
- Shader selection based on mesh and material properties (almost done)
- Better instancing
- Python bindings are currently very limited
- More documentation and user-friendliness
