Thank you wila for your swift response.

Before I sent my first post, I went through different other posts on this matter, which let me think, this dedication of hardware is possible (e.g. using more than one graphics card and dedicate one to a certain VM) - seems, that their problems were based on the question, how VmWare Pro can access the graphics card on the host. And this is not the problem with my installation.

So: following the explanation in your link, this is more the question, how I can tell Meshlab, that the "VMWare SVGA 3D" GC of the device manager is a valid graphics card, which it should use.

Maybe someone has a idea here?
