Question regarding ./photoscan.sh -r script -platform offscreen #2

Closed mrgloom closed 6 years ago

mrgloom commented 6 years ago

As I can see here https://agisoft.freshdesk.com/support/solutions/articles/31000133141-how-to-run-the-script-in-headless-mode-from-the-command-line I can run Photoscan without X-server, like: ./photoscan.sh -r script -platform offscreen

But I wonder do I steel need VirtualVNC, VirtualGL, etc. if I don't run Photoscan via GUI? Or maybe Photoscan still will be working but slower and I need some extra work? here I'm more talking about of using Photoscan with GPU, does it need something like 'hardware acceleration'?

No, for headless computations (even with GPU usage via OpenCL/CUDA) you don't need to install virtualgl - you only need to install GPU drivers for CUDA/OpenCL. If you use NVidia GPUs - you can just check your drivers with executing nvidia-smi (it should list all GPUs).
