Geometry nodes: How to capture nearest curve point?

[Zebrahead]

Hi Radek,
you could calculate the Winding Number to check if the curve goes clockwise or counter clockwise:

GeoNodes MeshToCurve Index Order

Hi mechandrius, not entirely sure what you want to do but you can calculate the Winding Number to check if a curve is reversed or not. Assuming we have a mesh and want to extrude a profile along the edges with a Curve to Mesh node: As you already noticed, some of the curves go in a clockwise and some in a counter clockwise direction (as can be seen by the flipped normals). [grafik] To calculate the winding direction, we first have to center the positions of our curves and then bring them o…

However you need to specify a “center point” which needs to be inside the curve… could be the center of the bounding box for example but that’s not always 100% inside
