" The code below is to show how a heirarchy of objects can be made within a scenegraph.
In other words, how there can be a parent/child relationship between objects such
that when a parent is rotated or translated, the children move is respect to it's
parent movement. A robotic arm is used in this example because this is what I'm
using OSG for."
Notes from Robert Osfield, I've merged osgWidget trunk, and added/changed CMakeLists.txt file to make it suitable for inclusion in the core OSG, and moved imagery/scripts/shaders out into OpenSceneGraph-Data
- Added osgviewerCocoa example to APPLE builds
- Fixed corrupt Xcode project generation with CMake 2.6 dealing with ADD_DEFINITIONS and CMake Policy CMP0005 on Leopard
- Resolved CMP0006 warning for examples and programs by setting BUNDLE DESTINATION to same as RUNTIME DESTINATION with CMake 2.6
- Fixed freetype plugin on Leopard to avoid OpenGL linking problem
- Figured out how to use a custom Info.plist included in the project (see osgviewerCocoa application CMakeLists.txt)"
creating subclasses of osg::Array that referenced data
stored an application's internal data structures. I took
a stab at implementing that and ran into a couple of
downcasts in Geometry.cpp. Enclosed is my take at fixing
those along with a simple example of how to do this."
Below is the changes made to the included files. The examples CMakeList.txt file was not included but the code change needed for osgviewerMFC inclusion is listed below.
CMakeList.txt:
This is a little different than other example cmakelist.txt files in that I could not use the setup_example macro. I had to go in and extract out the important parts of the macro and inline them in the CMakeList.txt file so that I could add the WIN32 declaration into the ADD_EXECUTABLE() statement. In the future the setup_example macro might be modified to support osgviewerMFC but this is special case so you might not want to muddy the water for one example.
MFC_OSG.h:
This file had some small changes:
From: #include <osgViewer/GraphicsWindowWin32>
To: #include <osgViewer/api/win32/GraphicsWindowWin32>
Also added two new function declarations
Void PreFrameUpdate(void);
Void PostFrameUpdate(void);
MFC_OSG.cpp:
This file changed only in that I am explicitly showing the viewer run loop and added the two new functions in the MFC_OSG.h file.
