This node is used to smooth out the effect of point deformations by a copy of the geometry before it was deformed.
In general, the deformation can be from any source (eg. from simulation).
Subset of points to smooth.
The weighting method used for smoothing.
Fastest method but assumes that the edge lengths are roughly the same everywhere.
Uses the edge length to weight the smoothing so that more details are maintained. It can also prevent points from seemingly drift along the surface.
The number of smoothing iterations to apply. More iterations result in smoother results. Generally, more iterations are needed for the same amount of smoothing for geometry that has higher point counts at the same size.
The amount of smoothing applied for each iteration. Larger step sizes result in smoother results. If there are artifacts in the results, try using smaller step sizes along with more iterations (at the expense of longer cook times).
When enabled, the frames built from the input geometry are first symmetrized using Symmetry Axis. This ensures that points across from each other on the mirror plane will be deformed in a consistent manner.
The mirror plane’s normal axis used for Symmetrize. Mirror points across this plane will be deformed in a consistent manner.
Pin Border Points
By default, delta mush will smooth everything. Turning this on will prevent the smoothing of border points that lie along unshared edges. For curves, only the end points are considered as border points.
Recompute Affected Normals
Recomputes any point (or vertex) normals that are affected by the smoothing operation. This option has no effect if the input geometry does not have a normal attribute.
Clamp Step Size
When enabled, the step size value will be limited to be between 0 and 1 since the algorithm works best in this range.
