Techie -

Nice, thanks Jeff!

I think it's doing some 2D vector-to-HSV mapping but I couldn't find any built-in OpenCL functions to do that. I found an algorithm that seems to work, it's not exactly matching the original but it's close, see attached.

Hi,

Version 1.4 has been released with the following changes:

• Added a "Tile Geometry" parameter so the generated SDF can tile seamlessly.
  
• Added parameters to allow using primitive attributes to set curve thickness and whether closed curves should be filled.
  
• Added a "Union Curves" parameter which unions overlapping closed curves and removes the overlapping areas from the SDF.
  
• Fixed an issue where closed cubic Bézier curves were sometimes not filled correctly.
