Information about the package, VirtualGL, which is shipped with common Linux distributions. The VirtualGL package is designed for, A toolkit for displaying OpenGL applications to thin clients.
A toolkit for displaying OpenGL applications to thin clients
VirtualGL is a toolkit that allows most Unix/Linux OpenGL applications to be remotely displayed with hardware 3D acceleration to thin clients, regardless of whether the clients have 3D capabilities, and regardless of the size of the 3D data being rendered or the speed of the network. Using the vglrun script, the VirtualGL "faker" is loaded into an OpenGL application at run time. The faker then intercepts a handful of GLX calls, which it reroutes to the server's X display (the "3D X Server", which presumably has a 3D accelerator attached.) The GLX commands are also dynamically modified such that all rendering is redirected into a Pbuffer instead of a window. As each frame is rendered by the application, the faker reads back the pixels from the 3D accelerator and sends them to the "2D X Server" for compositing into the appropriate X Window. VirtualGL can be used to give hardware-accelerated 3D capabilities to VNC or other X proxies that either lack OpenGL support or provide it through software rendering. In a LAN environment, VGL can also be used with its built-in high-performance image transport, which sends the rendered 3D images to a remote client (vglclient) for compositing on a remote X server. VirtualGL also supports image transport plugins, allowing the rendered 3D images to be sent or captured using other mechanisms. VirtualGL is based upon ideas presented in various academic papers on this topic, including "A Generic Solution for Hardware-Accelerated Remote Visualization" (Stegmaier, Magallon, Ertl 2002) and "A Framework for Interactive Hardware Accelerated Remote 3D-Visualization" (Engel, Sommer, Ertl 2000.)
Control the VirtualGL package with the following handy commands outlined below.
yum install VirtualGL
This command will install VirtualGL on the server.
yum remove VirtualGL
This command will un-install VirtualGL on the server. When you run this command, you will be asked if you are sure that you want to remove VirtualGL, so you have to manually confirm that you want to do this.
yum -y remove VirtualGL
This command will un-install VirtualGL on the server. When you run this command with th e -y flag, you will not be prompted to check that you are sure you want to remove the package - so be sure you absolutely want to remove VirtualGL when using the -y flag.
yum update VirtualGL
This command will update VirtualGL to the latest version. When you run this command, you will be asked if you are sure that you want to remove VirtualGL, so you have to manually confirm that you want to do this.
yum -y update VirtualGL
This command will update VirtualGL to the latest version. When you run this command with the -y flag, you will not be prompted to check that you are sure you want to remove the package - so be sure you absolutely want to remove VirtualGL when using the -y flag.
yum info VirtualGL
This command will show you core information about the VirtualGL package.
yum deplist VirtualGL
This command will show you the dependencies for VirtualGL. Thankfully, when using Yum, if dependencies are required, these are also installed at the same time so you don't have to worry too much about that.
yum check-update VirtualGL
This command will check if there is an update waiting on VirtualGL. When you run this command this will return nothing if there is nothing to update, or, will return the package name if the package is due to be updated.
