Scale by normal direction until find geometry center

Recommended Posts

Posted (edited)


I'm pretty sure that is an already solved question but I can't find the solution.

The idea is to scale a random geometry each point by his normal until a minimum value that would be the center of the shape ( similar to the Straight_Skeleton_3D node does).

The idea is to be able to shrink a geomity until a minimum point without generating crossed geometres. Similar to an erosion. I would like to store the min value and use it later in a shader to animate it.

Any idea?

Hi Konstantin,

Many thanks for the answer. That approach sounds interesting I-m gonna take a look.

For my side I tried with Labs Skeleton 3d and then XYZDist to find the closes position of the mesh on the skeleton curves. The result is quite acceptable too.
