SubdivMorph demo morph vertices between original and subdivided.

Usage


var filter = GetComponent<MeshFilter>();

// Require a mesh to weld (require to remove duplicated vertices)
var welded = SubdivisionSurface.Weld(filter.mesh, float.Epsilon, filter.mesh.bounds.size.x);

var mesh = SubdivisionSurface.Subdivide(
  welded,   // a welded mesh
  2,        // subdivision count
  false     // a result mesh is welded or not
);
filter.sharedMesh = mesh;

See demo scenes for details.

Compatibility

tested on Unity 2017.0.3, windows10 (GTX 1060).
