Geometry Nodes: Add Loose Ends mode to Curve Trim node. Authored by Charlie Jolly (charlie) on Jan 5 2022, 2:46 AM.
Details
This mode trims the loose ends from a curve. Adapted from GP trim stroke operator, this removes loose ends from a curve. Use case: When drawing paths this helps tidy up the loose ends. Imagine drawing a fence with a curve and you don't want the ends to overlap.

Event TimelineComment Actions This is an interesting idea, but maybe it's better to generalize the behavior, for example to retrieve a factor on each spline that it intersects itself. Then again, the fact that a spline can intersect itself multiple times does complicate things. Either way, I just have a feeling that this feature is a little too specific. But I guess it is useful, especially if you want to fill a freehand drawing maybe. Comment Actions I thought about generalizing it but the main use case is to tidy up hand drawn curves which this does non-destructively. Curve Trim node seems a logical place for it unless there was a Curve Tidy node that had this and other ops like Join Ends. Your idea for outputting intersections should be a different node. A Curve Intersection node would provide a list of points of all intersections for connected Curves. Comment Actions I wonder if a generalization of this node would be as a combination of the "Curve Intersections" node and the "Trim Curves" node. Either way, CurveEval has been removed, so this would have to use the new curves type and the new trim implementation. Comment Actions Update and rebase to use new curve types. This caculates the loose This doesn't move the start and end points after trimming like the previous code Added curve function evaluated_positions_for_curve as this is required for There maybe some logic to have this part of a curve intersections node but |
