Radome

Radome is a platform for realtime interactive visualization on a dome. It manages both 2D and 3D content for projection onto a fulldome installation with multiple projectors.

This is pre-release software optimized for our particular circumstances and hardware, but it should theoretically be useful to other people doing projection onto skinned domes (or, with small modifications, other geometry.)

Radome has been tested on OSX 10.8 through 10.10, built with both Xcode 5 and 6, and uses Syphon to exchange video with other software.

Windows support is newer but has so far tested well on Windows 7 and the Windows 10 beta, built with Visual Studio 2012 Express. Inter-app video uses the Spout 2 library.

Key features

• Handles projector transformation of up to 4 projectors
• Supports Matrox Triplehead output, individual outputs, and mixed scenarios
• Displays animated 3D content onto dome surface in real time, for game worlds or interactive visualization
• Warps 2D content to the dome surface using customizable shader algorithms; plays fulldome masters
• Support Syphon (OSX) and Spout (Windows) for receiving video input from other video software & devices
• Simple C++ plugin interface for interactive content

Known Issues

• Physical model is not yet fully correct, some fudging of measured distances and angles is required
• Built-in support for 3D content interactivity is limited (but plugins can implement custom interaction with OSC)
• No feathering of overlapping projectors when using front projection
• Only supports domes (arbitrary geometry coming soonish)
• User experience somewhat harmed by limited openFrameworks application tooling (future version may switch to JUCE)

Building Radome

Radome is built with openFrameworks v0.8.4. The following non-core addons are required:

• ofxCubeMap
• ofxUI
• ofxSyphon (OSX only)
• ofxAutoReloadedShader
• ofxAppGLFWWindowMulti

Detailed instructions:

1. Download openFrameworks v0.8.4

2. Clone the following oF extensions into the addons folder:

• ofxSyphon (head revision) (OSX only)
• ofxCubeMap (head revision)
• ofxAutoReloadedShader (head revision)
• ofxAppGLFWWindowMulti (fork)
• ofxUI (fork)

cd of_v0.8.4_osx_release/addons
git clone https://github.com/astellato/ofxSyphon
git clone https://github.com/andreasmuller/ofxCubeMap
git clone https://github.com/andreasmuller/ofxAutoReloadedShader
git clone https://github.com/Dewb/ofxAppGLFWWindowMulti
cd ofxApplGLFWWindowMulti
git checkout focus
cd ..
git clone https://github.com/Dewb/ofxUI
cd ofxUI
git checkout radome

3. Download or clone radome into the same parent folder as openFrameworks. (Do not put it in the apps folder.)
4. Open osx/radome.xcodeproj (OSX/Xcode) or windows/radome.sln (Windows/Visual Studio 2012) and build.
