Parameters
Return type

DynamicMesh

classmethod get_all_triangle_polygroup_i_ds(target_mesh, group_layer, polygroup_i_ds_out) -> (DynamicMesh, polygroup_i_ds_out=GeometryScriptIndexList)

Create list of per-triangle Polygroup IDs for the Polygroup in the Mesh warning: if the mesh is not Triangle-Compact (eg GetHasTriangleIDGaps == false) then the returned list will also have the same gaps

Parameters
Returns

polygroup_i_ds_out (GeometryScriptIndexList):

Return type

GeometryScriptIndexList

classmethod get_polygroup_i_ds_in_mesh(target_mesh, group_layer, polygroup_i_ds_out) -> (DynamicMesh, polygroup_i_ds_out=GeometryScriptIndexList)

Create list of all unique Polygroup IDs that exist in the Polygroup Layer in the Mesh

Parameters
Returns

polygroup_i_ds_out (GeometryScriptIndexList):

Return type

GeometryScriptIndexList

classmethod get_triangle_polygroup_id(target_mesh, group_layer, triangle_id) -> (int32, is_valid_triangle=bool)

Get Triangle Polygroup ID

Parameters
Returns

is_valid_triangle (bool):

Return type

bool

classmethod get_triangles_in_polygroup(target_mesh, group_layer, polygroup_id, triangle_i_ds_out) -> (DynamicMesh, triangle_i_ds_out=GeometryScriptIndexList)

Create list of all triangles with the given Polygroup ID in the given GroupLayer (not necessarily a single connected-component)

Parameters
Returns

triangle_i_ds_out (GeometryScriptIndexList):

Return type

GeometryScriptIndexList

classmethod set_num_extended_polygroup_layers(target_mesh, num_layers, debug=None) → DynamicMesh
