geo/M2DSimplify
Removes points from a 2D outline without changing its shape much.
Manifold Operations
Drops any vertex that sits within `epsilon` of the line between its neighbours, so an outline that came out of a contouring step, an import or a boolean loses the points that were not carrying any shape. The result is a cross section again.
The shape is what changes least and the point count is what changes most, which is the point: a contoured outline can carry thousands of vertices that no longer describe anything, and everything downstream pays for them. geo/SDFCreate has a hard segment limit and names this node when an input goes past it.
Raise `epsilon` too far and real corners start to go, so it is worth watching the outline rather than only the count.
Parameters
| Name | Type | What it does |
|---|---|---|
| epsilon | Float | How far a vertex may sit from the line between its neighbours and still be dropped, in model units. 0 removes only exactly collinear points. Raise it until the count comes down, and stop before the corners you care about go. |
