I’ve uploaded a patch that adds SDF functions to the Shader nodes in Blender. The patch is mostly working ok but it could really do with some artist feedback to polish how these functions should be implemented. If you are able to build Blender, please try out the patch. If you have some ideas on how you would use SDF functions that would be great too.
Based on the work of Inigo Quilez. Please see Inigo’s website for further information.
