lagrange.packing.repack_uv_charts(mesh, *, uv_attribute_name='', chart_attribute_name='', normalize=True, margin=0.0010000000474974513)

Pack UV charts of a given mesh.

The UV attribute is updated in place.

Parameters:

  • mesh (lagrange.core.SurfaceMesh) – The mesh with UV attribute.

  • uv_attribute_name (str) – Name of the indexed attribute to use as UV coordinates. If empty, the first indexed UV attribute will be used.

  • chart_attribute_name (str) – Name of the facet attribute that groups facets into UV charts. If empty, it will be computed based on UV chart connectivity.

  • normalize (bool) – Whether the output should be normalized to fit into a unit box. When false, the packed charts preserve their original scale but are still translated so the minimum UV is at the origin.

  • margin (float) – Minimum allowed distance between two boxes. When normalize is true, this value is measured in the normalized [0, 1] output domain. When normalize is false, it is interpreted as an absolute distance in the original UV units.

Returns:

None. The UV attribute is modified in place.

Return type:

None
