The best way is to use viewshed (observer point does not seem necessary based on you question, except if you want to know which spire can see which WTG). First you determine the locations where you could see your WTG (viewshed of the spires), then you use "extract multivalue to point" to transfer this information from the resulting raster to each WTG point. ...

GIS wont be a big drain on your graphics card. You might not want to hear this, but even an Intel integrated graphics chip will do fine. I definitely wouldn't go for a workstation graphics card, they are used for precision, not performance, and are way too expensive. If I were you, I'd get something nice and light so that you can carry it around for school ...

If I were doing this on the command line (and assuming I understand what you're asking), I'd use the -translate_then_scale_x and -translate_then_scale_y. This will offset the point cloud by the translate amount, then scale it. Then you can translate it back using -translate_x and -translate_y. So, if the point of origin of the scale is 1000, 2500, and the ...
