SurfaceScanning, export result as CSV #82

Open krtschmr opened 5 years ago

krtschmr commented 5 years ago

Is it possible to just run the surface scanning and export the result as a CSV file so we can replicate the surface as a 3D Model in Fusion or somewhere else? should either choose if XML or csv

Hi, .hmap files are actually just xml files. They don't use any existing standard, so you can't just plug them into another program, but a quick python script can convert a height map to any format you need.

ya, i can do sublime and replace it

<point X="([0-9]+)" Y="([0-9]+)"> with then $1,$2, and then replace </point> withnothing and it's done.

i wonder why the points are starting from 0,0 instead of negative values, so 0,0 would be the center?

I can't remember why I did it that way, this entire file format is pretty horrible. The offsets should be stored somewhere in the .hmap.
