Hi hesicong(?),
Somehow I missed your email until just now, but thanks for your feedback! The Osg.GraphicsContext.Traits issue you've run into is a known deficiency. Currently public member variables are not wrapped other than via OSG-provided getters/setters. Support is available for this in osgIntrospection, it just hasn't been implemented yet in the wrappers. Unfortunately there's no good way to work around this problem at the user level. I did add one parameter versions of the osgDB::read* functions. That's now checked in to SVN. -Mike ________________________________ From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of hesicong2006 Sent: Tuesday, June 26, 2007 3:58 AM To: osg users Subject: Re: [osg-users] Announcing osgDotNet: C#/.NET wrappersfor OpenSceneGraph Mike Wittman 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.

I have tested it. I have built the generator, and got the final solution. Then I built the final code, all seems to be OK. Then I tested the the program in the wiki, that's good, a full screen colorful square is displayed. Now I try to do further work. I want to render this to an C# control. I have managed to do this by using C++/CLI: void SetRenderSurface(Control^ control) { HWND hwnd=(HWND)control->Handle.ToInt32(); osg::ref_ptr<osg::Referenced> windata = new osgViewer::GraphicsWindowWin32::WindowData(hwnd); osg::ref_ptr<osg::GraphicsContext::Traits> traits=new osg::GraphicsContext::Traits; traits->x = 0; traits->y = 0; traits->width = control->Right-control->Left; traits->height = control->Bottom-control->Top; traits->windowDecoration = false; traits->doubleBuffer = true; traits->sharedContext = 0; traits->inheritedWindowData = windata; // We must set the pixelformat before we can create the OSG Rendering Surface // PIXELFORMATDESCRIPTOR pixelFormat = { sizeof(PIXELFORMATDESCRIPTOR), 1, PFD_DRAW_TO_WINDOW | PFD_SUPPORT_OPENGL|PFD_DOUBLEBUFFER, PFD_TYPE_RGBA, 24, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 24, 0, 0, PFD_MAIN_PLANE, 0, 0, 0, 0 }; HDC hdc = ::GetDC(hwnd); if (hdc==0) { ::DestroyWindow(hwnd); throw gcnew Exceptions::InitOpenGLFailedExpection(); } int pixelFormatIndex = ::ChoosePixelFormat(hdc, &pixelFormat); if (pixelFormatIndex==0) { ::ReleaseDC(hwnd, hdc); ::DestroyWindow(hwnd); throw gcnew Exceptions::InitOpenGLFailedExpection(); } if (!::SetPixelFormat(hdc, pixelFormatIndex, &pixelFormat)) { ::ReleaseDC(hwnd, hdc); ::DestroyWindow(hwnd); throw gcnew Exceptions::InitOpenGLFailedExpection(); } gc=GraphicsContext:o:createGraphicsContext(traits.get()); } But I can find Osg.GraphicsContext.Traits but I can't find any property or public various which I can set the x,y,width,height and etc like C++. I looked at the assembly, Traits have no other public member. And it inherited only from Reference, but the source code of C++ is inherited from Reference and ScreenIdentifier. These is also another problem. The OsgDB.global.readNodeFile do not have one parameter version like C++: inline osg::Object* readObjectFile(const std::string& filename) { return readObjectFile(filename,Registry::instance()->getOptions()); } Hope you can correct these problems and make .NET version OpenSceneGraph more powerful! I'll try your lastest SVN version whenever you fixed these problems! Thanks!
