Hi Jason,
Thanks for the report. The problem looks to be due to some over-eager casting in the presence of multiple inheritance (of osgViewer::View in this instance)... I'll have to think a bit about the appropriate solution. -Mike ________________________________ From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Jason Beverage Sent: Monday, June 25, 2007 10:52 PM To: osg users Subject: Re: [osg-users] Announcing osgDotNet: C#/.NET wrappers forOpenSceneGraph Hi Mike, Awesome job on the wrappers, I've got an embedded graphics window running with Tao in a little test application now. One issue I'm having is that I'm getting exceptions when I try to add a camera manipulator. Here is the exception that I'm getting: Unhandled Exception: System.InvalidOperationException: Handle is not initialized . at System.Runtime.InteropServices.GCHandle.FromIntPtr(IntPtr value) at ___WS.SmartHandle<OsgViewer::Viewer ^>.makeWeak(SmartHandle<OsgViewer::Vie wer ^>* ) at ___WS.?A0x27774b4a.refCountedAdapterFactory<class OsgViewer::___Viewer_ada pter>(Void* native, Boolean __unnamed001) at ___WS.VTableTypeWrapperFactory.getWrapper<class osgGA::GUIActionAdapter>(G UIActionAdapter* native, Boolean isReference) at OsgGA.___UFOManipulator_adapter.home(___UFOManipulator_adapter* , GUIEvent Adapter* x, GUIActionAdapter* param2) at osgViewer.View.setCameraManipulator(View* , MatrixManipulator* ) at OsgViewer.View.setCameraManipulator(MatrixManipulator manipulator) at GeometryTest.Form1..ctor() in C:\dev\DWA\GLRSS\GeometryTest\Form1.cs:line 21 at GeometryTest.Program.Main() in C:\dev\DWA\GLRSS\GeometryTest\Program.cs:li ne 17 I can manually set the camera position using viewer.getCamera().setViewMatrixAsLookAt(eye, center, up) though. I'm really excited about this project:) Thanks, Jason On 6/25/07, Mike Wittman <[EMAIL PROTECTED]> wrote: Hi everyone, I'm pleased to announce the release of osgDotNet, a binding of the OpenSceneGraph libraries to the .NET/CLR platform. osgDotNet allows OpenSceneGraph to be used and extended from C# with an API that closely mirrors the C++ interface. The initial version, osgDotNet 0.8, supports OpenSceneGraph 2.0 on .NET 2.0 and later. This release should be considered beta -- it's mature enough to be usable although there are still some rough edges. I'd invite anyone who may be interested in using OpenSceneGraph from C# to jump in and give it a try. Wrapper assembly binaries for x86 and x64, the generator that created them, and information on getting started with both are on the osgDotNet Trac wiki: http://www.openscenegraph.com/projects/osgDotNet Thanks go to my employer, Seismic Micro-Technology, Inc., for releasing the osgDotNet wrapper generator under the GPL, and Robert Osfield and Jose Luis Hidalgo for hosting the project on the OpenSceneGraph server.
