Low Spacing calculations takes tens of minutes to complete, Only using 10% of CPU #38

Hello @jawensi

I think the issue is that the process is not MultiThreaded. Is that correct? Is there any way to enable it, or if not, have you considered implementing it?

I use your tool to create highly detailed maps for a MSLA 3d printer with a print resolution of 0.05mm, which can really show every triangle face if I dont set the Spacing parameter low enough. I typically use 0.06 if there are any cliffs in the terrain to minimize the polygons on said steep cliff.

With that in mind, it can take a very long time to do these calculations at this resolution, and my CPU 8 Core CPU stays around 10-12%

Cheers Max

Actually, I came across the exact same problem today. No matter if I use full extend or a selected area, it always takes ages to calculate.
