Re: [osg-users] OSG errors when running on a virtual machine
Thanks for the tip, Alistair. I found precompiled Mesa libraries at the two links below and copied open32.dll and glu32.dll into the executable's directory. It seems to be working better now, though I get the following error messages. But I understand this is beyond OSG, I'll try to figure it out. /AJ -- Precompiled Mesa drivers for Windows: http://mycodelog.com/2010/05/15/gllibs/ http://www.mediafire.com/?8hbxdg50s6nndht -- PixelBufferWin32::init(), Error: some wgl extensions not supported Warning: detected OpenGL error 'invalid enumerant' at after RenderBin::draw(..)

Re: [osg-users] OSG errors when running on a virtual machine
Thanks to everyone for the input. So this seems like a dead end for now! But two things I can try: MESA as Aurelien suggests, and some other VM which may support the necessary OpenGL functionality.

Re: [osg-users] OSG errors when running on a virtual machine
Mesa works for us on Windows, just by dropping the GLU32.dll and OPENGL32.DLL into the directory with your executable. We use it to support OpenSceneGraph rendering via Remote Desktop Protocol. It's quite good in that it supports OpenGL version 2.1 and GLSL 1.2, but it's not very fast, it's effectively just for last-resort compatibility rather than any sort of decent performance unless your scenes are very simple. The biggest problem with Mesa for Windows is getting it. The build instructions are a bit complex, we got prebuilt DLLs from someone on this list, but looking back through the mail archive the dropbox download links are no longer working.

Re: [osg-users] OSG errors when running on a virtual machine
Hi, it looks like the driver in your virtual machine does not support OpenGL =2.0. The function pointers for some newer features can not be found. So things like shaders, occlusion queries, framebuffers and instancing will not work. If fear there is nothing much you can do about that. You can only try to update VMWare, VirtualBox or whatever product you are using and hope it fixes the problem. The 3D hardware acceleration in a virtual machine is generally not that good. Thank you!

Re: [osg-users] OSG errors when running on a virtual machine
Hi, according to the homepage of VMWare they support DirectX 9.0 and OpenGL 2.1 and VirtualBox has DirectX 9.0 and OpenGL(no version mentioned) support. So hardware accelaration should work, if a new version of VMWare or VirtualBox is used. Thank you!

Hi Marcel, 2013/9/5 Marcel Pursche marcel.purs...@student.hpi.uni-potsdam.de Hi, according to the homepage of VMWare they support DirectX 9.0 and OpenGL 2.1 and VirtualBox has DirectX 9.0 and OpenGL(no version mentioned) support. So hardware accelaration should work, if a new version of VMWare or VirtualBox is used. Don't expect the drivers of the virtual machine for OpenGL to be fully implemented. They may not have all extensions or features you need. At least not yet. Cheers. Thank you!

Re: [osg-users] OSG errors when running on a virtual machine
Hi, I've got some bad experience with virtual machines. The 3D hardware acceleration in a virtual machine is generally not that good. In fact, hardware acceleration is usualy not available at all on a Virtual Machine. Because this is a virtual machine. Just like a remote session on windows : you can't access directly to the hardware. There is 2 potential solutions : - try finding a virtual macine system which allow direct access to the hardware (don't know the status, but NVidia made a lot of efforts on this since last year) - try a full software openGL implementation, like MESA Cheers, Aurelien -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=56129#56129 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
