I’m wondering what are current practical solutions to use vtk render to support the Powerwall([Powerwall - Wikipedia](https://en.wikipedia.org/wiki/Powerwall)). Each process will start a vtk rendering window and render specific region of object according to the position of the display.

Thanks,  
Zhe

Hello, I think tiled rendering in VTK will help you.

ParaView has this capability builtin see:

```pvserver
...
[Option Group: Tile Display]
  Tile-display specific options 
  
  Options:
    --tdx,--tile-dimensions-x INT
                                Number of displays in the horizontal direction. 
                                
    --tdy,--tile-dimensions-y INT
                                Number of displays in the vertical direction. 
                                
    --tmx,--tile-mullion-x INT Size of the gap in pixels between displays in the horizontal direction. 
                                
    --tmy,--tile-mullion-y INT Size of the gap in pixels between displays in the vertical direction
