Blender 4.2 EdgeFlow v1.0 mesh geometry Addon Free Download

This addon adds a set of operators which help when dealing with curved shaped meshes.

Core functionality aims at working with edge loops, but there are also a couple of tools which work on vertex selections too. The main workhorse is the set flow operator which helps to fit an edgeloop to the curvature of the surrounding mesh.

My stab at implementing a set flow operator for blender, which is a popular tool in many 3d applications. This adjusts the edgeloop via a spline interpolation such that it respects the flow of the surrounding geometry. The tool operates orthogonal to the direction of the flow of the edgeloop, indicated by the orange in the image.

Mix: Blend between intial vertex positions and the interpolated result.
Tension: Controls the strengh of offset.
Iterations: How often the operation will be repeated.
Min Angle: Cut off angle of the smoothing. Falls back to a linearely extrapolated position if the angle is beyond threshold.

In this example the control points for the spline smoothing are around the corner – which creates a nasty bulge. With the min angle one can force the alghorithm to find a better solution.

Blend Mode:

Absolute: Use a number of vertices along the edgeloop to control the blend length.
Factor: Blend length defined by a factor of the length from the edgeloop.
Blend Start: Number of vertices from the start of the edgeloop | The partial length from the start of the edgeloop.
Blend End: Number of vertices from the end of the edgeloop | The partial length from the end of the edgeloop.
Blend Curve: Linear or Smoothstep blend of the values along the edgeloop.

Notice how the shape changes from straight to curved at the right image. This obviously only works for edgeloops which are not cyclic.
