Integrate this with WebGL?
Any plans to Integrate this with WebGL such that the 3d views are renderable in a web browser?
Anaconda/Python
The SWIG-produced Python interface doesn't work on a Mac with an Anaconda distribution of Python.
A workaround is to add -undefined dynamic_lookup to the linker properties in swig/CMakelists.txt like so:
Replace:
SWIG_LINK_LIBRARIES(PyOFInterfaceC ${PYTHON_LIBRARY} OpenFrames_Interface_C)
with:
if(APPLE)
# for anaconda
SWIG_LINK_LIBRARIES(PyOFInterfaceC OpenFrames_Interface_C)
SET_TARGET_PROPERTIES(${SWIG_MODULE_PyOFInterfaceC_REAL_NAME} PROPERTIES LINK_FLAGS "-undefined dynamic_lookup")
else()
SWIG_LINK_LIBRARIES(PyOFInterfaceC ${PYTHON_LIBRARY} OpenFrames_Interface_C)
endif()
And this:
SWIG_LINK_LIBRARIES(PyOFInterfaceIFORT ${PYTHON_LIBRARY} OpenFrames_Interface_IFORT)
with this:
if(APPLE)
# for anaconda
SWIG_LINK_LIBRARIES(PyOFInterfaceIFORT OpenFrames_Interface_IFORT)
SET_TARGET_PROPERTIES(${SWIG_MODULE_PyOFInterfaceIFORT_REAL_NAME} PROPERTIES LINK_FLAGS "-undefined dynamic_lookup")
else()
SWIG_LINK_LIBRARIES(PyOFInterfaceIFORT ${PYTHON_LIBRARY} OpenFrames_Interface_IFORT)
endif()
I think this breaks linking with the Python.org distribution though. Ideally, it should work for both.
SWIG 4.1.1 Failure
For the build script I show in Issue #5, if I update the SWIG version to 4.1.1 (which is the latest), the build fails. I get errors like this:

Again, this is on an M1 Mac, latest develop OpenFrames commit (67cce87).
How about add a funciton like(setCameraManipulator) to View?
When i read .earth，FollowingTrackball is different to use.
So maybe we can add a function to selecet a Manipulator for Class View.
Maybe we can add a funciton like(setCameraManipulator) to View?
osgearth .earth file integration with htcvive
Hi Ravi,
I have built openframes with openvr and osgearth successfully.
I ran ofviewer --vr .earth file . it runs successfully but vive controllers are not working ?? any manual towards that?
thanks
Jai
NSWindow drag regions should only be invalidated on the Main Thread!
On an Apple M1 Mac (MacOS Ventura 13.1, clang 14.0.0), I can't get the examples to work.
For example, when running ofcones I get:
2023-02-28 15:33:31.630 ofcones[56746:18375509] *** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'NSWindow drag regions should only be invalidated on the Main Thread!'

If I run ofqt_demo.py I get a similar error (-[NSOpenGLContext setView:] must be called from the main thread.)
I'm compiling it with the following script (using conda for all the dependencies):
#!/bin/bash
# version numbers of dev tools:
export PYTHON_VERSION=3.9
export OSG_VERSION=3.6.5
export CMAKE_VERSION=3.25
export SWIG_VERSION=4.0
export NUMPY_VERSION=1.24
export PYQT_VERSION=5.15
export NINJA_VERSION=1.11
# magic to make conda work:
eval "$(conda shell.bash hook)"
# set up directories:
rm -rf ./build
mkdir ./build
# create the conda environment and activate it:
conda create --channel nodefaults --channel conda-forge --prefix ./build/osgenv --solver libmamba python=$PYTHON_VERSION openscenegraph=$OSG_VERSION cmake=$CMAKE_VERSION swig=$SWIG_VERSION numpy=$NUMPY_VERSION PYQT=$PYQT_VERSION ninja=$NINJA_VERSION
