classmethod auto_repair_normals(target_mesh, debug=None) → DynamicMesh

Auto Repair Normals

Parameters:
Return type:

DynamicMesh

classmethod compute_split_normals(target_mesh, split_options, calculate_options, debug=None) → DynamicMesh

Compute Split Normals

Parameters:
Return type:

DynamicMesh

classmethod compute_tangents(target_mesh, options, debug=None) → DynamicMesh

Compute Tangents

Parameters:
Return type:

DynamicMesh

classmethod flip_normals(target_mesh, debug=None) → DynamicMesh

Flip Normals

Parameters:
Return type:

DynamicMesh

classmethod get_mesh_per_vertex_normals(target_mesh, average_split_vertex_values=True) -> (DynamicMesh, normal_list=GeometryScriptVectorList, is_valid_normal_set=bool, has_vertex_id_gaps=bool)

Get a list of single normal vectors for each mesh vertex in the TargetMesh, derived from the Normals Overlay. The Normals Overlay may store multiple normals for a single vertex (ie split normals) In such cases the normals can either be averaged, or the last normal seen will be used, depending on the bAverageSplitVertexValues parameter.

Parameters:

  • target_mesh (DynamicMesh) –

  • average_split_vertex_values (bool) – control how multiple normals at the same vertex should be interpreted

Returns:

normal_list (GeometryScriptVectorList): output normal list will be stored here. Size will be equal to the MaxVertexID of TargetMesh (not the VertexCount!)

is_valid_normal_set (bool): will be set to true if the Normal Overlay was valid

has_vertex_id_gaps (bool): will be set to true if some vertex indices in TargetMesh were invalid, ie MaxVertexID > VertexCount

Return type:

tuple
