Using Unity I've been producing sculptural forms that look like this. It's made of patterns of cubes that twist around each other using a flocking algorithm. I'm trying to get it into a 3D printable format.
From unity I export a PLY that is a list of the co-ords of each cube that looks like:
format ascii 1.0
element vertex 17500
property float x
property float y
property float z
35 2.521441 0
34.72401 -2.06799 4.386663
33.90041 3.202552 8.704146
Then I've imported that into meshlab and run
Filters > Remeshing, Simplification and Reconstruction > Surface Reconstruction: Ball Pivoting with the default parameters.
This is the result (different iteration so doesn't match top image but similar) which is ok, but obviously not 3d printable.
Is there a better way of doing this in Unity to create a single mesh? I'd be happy with either a single mesh with individual lines or a mesh that makes a single shape as if it were shrink wrapped.
