Yes, it's possible, but I don't understand why you would need to access it on the client machine and not the server. Your previous message said that you were interested in getting at the pixels on the same machine as the 3D was being rendered, which is clearly not the client machine. Based on your previous description, I think you want to either intercept the 3D pixels via a VirtualGL transport plugin, or you want to use Xvfb along with VirtualGL to display the app into Xvfb and capture the output of Xvfb (which will contain both 2D and 3D pixels.) I really don't see what TurboVNC gives you in this case that you couldn't get from Xvfb, since you're not interested in actually displaying the pixels to the screen but rather just want to read them back for automated testing purposes.
