classmethod compact_mesh(target_mesh, debug=None) → DynamicMesh¶

Compacts the mesh’s vertices and triangles to remove any “holes” in the Vertex ID or Triangle ID lists.

Parameters:

target_mesh (DynamicMesh)
debug (GeometryScriptDebug)

Return type:

DynamicMesh

classmethod fill_all_mesh_holes(target_mesh, fill_options, debug=None) -> (DynamicMesh, num_filled_holes=int32, num_failed_hole_fills=int32)¶

Tries to fill all open boundary loops (such as holes in the geometry surface) of a mesh.

Parameters:

target_mesh (DynamicMesh)
fill_options (GeometryScriptFillHolesOptions) – specifies the method used to fill the holes.
debug (GeometryScriptDebug)

Returns:

num_filled_holes (int32): reports the number of holes filled by the function.

num_failed_hole_fills (int32):

Return type:

tuple

classmethod remove_hidden_triangles(target_mesh, options, debug=None) → DynamicMesh¶

Removes any triangles in the mesh that are not visible from the exterior view, under various definitions of “visible” and “outside” as specified by the Options.

Parameters:

target_mesh (DynamicMesh)
options (GeometryScriptRemoveHiddenTrianglesOptions)
debug (GeometryScriptDebug)

Return type:

DynamicMesh

classmethod remove_small_components(target_mesh, options, debug=None) → DynamicMesh¶

Removes connected islands (components) of the mesh that have a volume, area, or triangle count below a threshold as specified by the Options.

Parameters:

target_mesh (DynamicMesh)
options (GeometryScriptRemoveSmallComponentOptions)
debug (GeometryScriptDebug)

Return type:

DynamicMesh

classmethod remove_unused_vertices(target_mesh, debug=None) → DynamicMesh¶

Remove vertices that are not used by any triangles. Note: Does not update the IDs of any remaining vertices; use CompactMesh to do so.

Parameters:

target_mesh (DynamicMesh)
debug (GeometryScriptDebug)

Return type:

DynamicMesh

classmethod repair_mesh_degenerate_geometry(target_mesh, options, debug=None) → DynamicMesh¶

Removes triangles that have area or edge length below specified amounts depending on the Options requested.

Parameters:

target_mesh (DynamicMesh)
options (GeometryScriptDegenerateTriangleOptions)
debug (GeometryScriptDebug)

Return type:

DynamicMesh

classmethod resolve_mesh_t_junctions(target_mesh, resolve_options, debug=None) → DynamicMesh¶

Attempts to resolve T-Junctions in the mesh by addition of vertices and welding.

Parameters:

target_mesh (DynamicMesh)
resolve_options (GeometryScriptResolveTJunctionOptions)
debug (GeometryScriptDebug)

Return type:

DynamicMesh

classmethod select_hidden_triangles_from_outside(target_mesh, options, ignore_selection, transparent_selection, debug=None) -> (DynamicMesh, result_selection=GeometryScriptMeshSelection)¶

Select mesh triangles hidden from outside views, with optional filtering on view directions

Parameters:

target_mesh (DynamicMesh)
options (GeometryScriptSelectHiddenTrianglesFromOutsideOptions)
ignore_selection (GeometryScriptMeshSelection) – Optionally indicate parts of the mesh that should not be included in the ResultSelection, so do not need to be tested for occlusion *
transparent_selection (GeometryScriptMeshSelection) – Optionally indicate parts of the mesh that should not be considered occluding, e.g. transparent triangles *
debug (GeometryScriptDebug)

Returns:

result_selection (GeometryScriptMeshSelection): The fully occluded triangles of the target mesh (based on the options / transparencies, and excluding any IgnoreSelection triangles)

Return type:

GeometryScriptMeshSelection

classmethod snap_mesh_open_boundaries(target_mesh, snap_options, debug=None) → DynamicMesh¶

Snap vertices on open edges to the closest compatible open boundary, if found within the tolerance distance Unlike ResolveMeshTJunctions, does not introduce new vertices to the mesh

Parameters:

target_mesh (DynamicMesh)
snap_options (GeometryScriptSnapBoundariesOptions)
debug (GeometryScriptDebug)

Return type:

DynamicMesh

classmethod split_mesh_bowties(target_mesh, mesh_bowties=True, attribute_bowties=True, debug=None) → DynamicMesh¶

Splits Bowties in the mesh and/or the attributes. A Bowtie is formed when a single vertex is connected to more than two boundary edges, and splitting duplicates the shared vertex so each triangle will have a unique copy.

Parameters:
