Hi all,

I've made a new tool called SDF from Curves for Houdini 20.5 Copernicus that generates a 2D signed distance field from Bézier curves, polylines, or points. I hope you'll find it useful when making textures!

Awesome. Thank you! I was surprised this was not in the Copernicus by default

You're welcome LukeP!

I've released version 1.1 now which supports adding thickness to the curves and it also auto-detects if the geometry contains closed curves/polylines.

Hi,

I've released version 1.2 now which supports filled closed Bézier curves.
Support for filled closed polylines will hopefully come in a later version.

Hi,

Version 1.3 has been released with support for filled closed polylines and for generating a closed polyline from points.

Please note that there's a known issue where closed Bézier curves are sometimes not filled correctly. This will hopefully be fixed in a later version. A workaround can be to slightly move or rotate the points.

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.
