I should implement the transformation in my tool immediately after the scan,
because the scan is ordered with adjacent pixels, and therefore the calculation
of the normals is fast.
If I had done it on my test with my other tool for varous meshes that searches
the entire triangle map it would have taken too long.
What I want to add in the scan code is to eliminate the anti-aliasing pixels
over the background in the bitmap I'm scanning, because it produces unwanted
effects in the generated solids.
Nice and accurate your site!
I also work on DXF - STL - POV - INC conversion ...
