SplineTrace

SplineTrace is a MaxScript that can be used to:

- convert a 2D Image into spline shapes, where each spline corresponds to an interior or exterior contour (outline) in the image. Works best on Black/white images but can be used on Colour images by adjusting threshold value.

- create a flat 2D object which corresponds to the "black" areas of the image. Any internal "white" areas are removed from the object.

- quickly turn a plain 2D image into a solid 3D object.

- create a flat 2D shape or 3D Object from an existing spline (not just those created by this script)

ChangeLog:

v1.1
- Previews now shown as Black on White (instead of White on Black)
- Spline optimisation routines have been tweaked to keep edges straighter on all Optimisation Level settings.

v1.2
It seems that a couple of bugs sneaked in during the v1.1 update and these have now been corrected.

- Preview option not working when only Find Interior Borders was checked
- 'Unknown System Exception' generated when 'Create 3D Objects' was used when only 'Find Interior Borders' was checked.

v1.3
-- All mesh creation routines have been stripped and rebuilt, resulting in a 33% reduction in filesize and a 40% reduction in mesh creation times.

v1.3a
-- Fixed an "off by 1" issue where the script bombed when scanning images with pixels that touched the image border.
