Curve Fill node similar to Modo

Is there a Houdini equivalent of Modo's procedural curve fill operator? It works on one or more curves (and if they have opposite directions, it can cut holes) and has two options: grid and paving. See attachment. Thanks.

Hi,

is “curve fill” in modo restricted to planar curves?

If yes you can archieve similar results in houdini using the “triangulate2d-node”. If not you can always try to project the geometry

into a planar domain (perform the operation) and map the points back to the old position (@edit but this can probably challenging,

since you have only the curve point positions and not the positions of the whole grid).

Here is an approach using the triangulate2d-node and the intersect_all() function combined with the extruded geometry, to detect if a

primitive center is inside/outside. But the accuracy of intersect_all depends a bit on a scale level. It is also working (quite well)

if you have interections between the curves.

Thank you for the reply, Aizatulin. Modo's curve fill is not restricted to planar curves, but the polygons created will be all in one plane. The procedural node does create all quads, whether “grid” or “paving” is selected, and one has the option of picking flat “face”) or subdivided interpolation. The triangulate example you gave is useful, but generally I like to work with quads. That is an issue with Houdini's remesh and unfortunately, the Labs tool for quadremesher still does not work on OSX.
