This repository contains a widget based onQOpenGLWidget that is ableto wrap a viewer from theOpenSceneGraph library.This makes it possible to combine both toolkits in a thread-safe manner.

Moreover, the widget demonstrates several interaction mechanisms:

1. Rectangular selection processing
2. Pick handling
3. Node file writing (for debug purposes)

• Linux or MacOS X (see below for a brief discussion on supportingMicrosoft Windows)
• A recent C++ compiler with support for C++11
• CMake (minimum version 2.8.11)
• Qt5
• OpenSceneGraph

I am not familiar enough with graphics programming for Microsoft Windowsto fully support this as a target platform. Inissue 7, it was brieflydiscussed that some modifications are required for QtOSG to fullycompile/work under Microsoft Windows. If you want to target thisplatform, I would be glad for the help!

Thanks toMartial Tola, support forcompiling under Microsoft Windows has been added to the projectand I am looking forward to any comments.

$ git clone https://github.com/Submanifold/QtOSG$ cd QtOSG$ mkdir build$ cd build$ cmake ../$ make

Additional build options can be configured by issuingccmake . in thebuild directory. In particular, you can toggle the following options:

• WITH_PICK_HANDLER: toggle to compile with/without support for pointpicking
• WITH_SELECTION_PROCESSING: toggle to compile with/without supportfor rectangular selections

The demo application merely demonstrates basic usage of the widget.Don't expect too much! Start the application by issuing./qtosg in thebuild directory.

The following key bindings are active:

• d: writes the current scene graph to/tmp/sceneGraph.osg
• h: resets the view to home
• s: toggles selection processing (if compiled); if active, hold leftmouse button down to draw a selection rectangle; selected objects willbe shown on the console
