Dear all, actually, due to a conference, our department is not well-staffed. Therefore, we apologize for delayed answers on the users list.
To my best knowledge, we didn't try MITK and VirtualGL, yet. In general, MITK uses a custom build toolkit, called IIL, for 2D rendering, while 3D content is rendered by VTK. > The 3D image stays black though you can > see the correct image for a tiny moment while rotating it, so it looks > like it gets continuosly erased. Most likely this is a VTK related problem. It sounds like if the OpenGL buffer is not flushed properly. We are also aware of problems with some OpenGL drivers, beside the ones from Nvidia, where setting the VTK rendering mode to "immediate" may help. Check this out: vtkMapper::GlobalImmediateModeRenderingOn(); May be you also check out if VirtualGL has already been discussed on the vtkusers list.

Februar 2008 19:17 An: [email protected] Betreff: [mitk-users] MITK and VirtualGL Dear All, I am trying to run MITK remotely using the VirtualGL package (www.virtualgl.org) which allows to run imaging applications through the network without noticable delay in interactiion. The MITK itself (without VirtualGL) runs fine on the server desktop (CentOS 64 bit) as well as remotely through the standard X session (though extreamely slow in this case). When running through the VirtualGL there is a problem with redrawing which I am trying to pinpoint. The 3D image stays black though you can see the correct image for a tiny moment while rotating it, so it looks like it gets continuosly erased. The images in 2D planes display fine, but any annotations (say distance measurements) can be seen for a tiny moment and then get erased by the image itself. Other than that, image manipulations are extreamely smooth and fast through the remote connection, so I would realy like to feagure out on which side the problem occurs. So basically I have two questions: 1) Did anybody use MITK with VirtualGL? 2) Does MITK use the OpenGL overlay? VirtualGL requires the presense of the overlay support on the client machine, but I don't have it on both client and server and MITK works fine as I mentioned above. Thank you in advance for any input. Alex Lisovich ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
