classmethod apply_mesh_boolean(target_mesh, target_transform, tool_mesh, tool_transform, operation, options, debug=None) → DynamicMesh

Applies a Boolean operation (such as, Union, Intersect, and Subtract) to the Target Dynamic Mesh based on a Tool Dynamic Mesh.

Parameters:

• target_mesh (DynamicMesh) – Dynamic Mesh to be acted upon

• target_transform (Transform) – used to position the TargetMesh

• tool_mesh (DynamicMesh) – Dynamic Mesh that acts as the cutting tool

• tool_transform (Transform) – used to position the ToolMesh

• operation (GeometryScriptBooleanOperation) – selects the specific boolean operation

• options (GeometryScriptMeshBooleanOptions) – selects additional options that are applied to the result

• debug (GeometryScriptDebug)

Return type:

DynamicMesh

classmethod apply_mesh_iso_curves(target_mesh, options, per_vertex_value, iso_value=0.500000, debug=None) → DynamicMesh

Insert edges along the curve where the interpolated per-vertex values match a given isovalue

Parameters:

• target_mesh (DynamicMesh) – Dynamic Mesh to be updated.

• options (GeometryScriptMeshIsoCurveOptions) – Settings for processing to perform after inserting the curve edges

• per_vertex_value (GeometryScriptScalarList) – Values to interpolate, must be one per vertex

• iso_value (float) – Value at which to insert the new curve

• debug (GeometryScriptDebug)

Return type:

DynamicMesh

classmethod apply_mesh_mirror(target_mesh, mirror_frame, options, debug=None) → DynamicMesh

Mirrors a mesh across a plane, with optional cutting and welding of triangles.

Parameters:

• target_mesh (DynamicMesh) – Dynamic Mesh to be updated by the mirror operation.

• mirror_frame (Transform) – defines the plane used to mirror the TargetMesh.

• options (GeometryScriptMeshMirrorOptions) – selects additional clean-up operations performed after the mirror.

• debug (GeometryScriptDebug)

Return type:

DynamicMesh

classmethod apply_mesh_plane_cut(target_mesh, cut_frame, options, debug=None) → DynamicMesh

Applies a plane cut to a mesh, optionally filling any holes created.

Parameters:

• target_mesh (DynamicMesh) – Dynamic Mesh to updated with the cut

• cut_frame (Transform) – defines the plane used to cut the TargetMesh

• options (GeometryScriptMeshPlaneCutOptions) – selects additional clean-up operations performed after the cut.

• debug (GeometryScriptDebug)

Return type:

DynamicMesh

classmethod apply_mesh_plane_slice(target_mesh, cut_frame, options, debug=None) → DynamicMesh

Slices a mesh into two halves, with optional hole filling.

Parameters:

• target_mesh (DynamicMesh) – Dynamic Mesh to be updated by the slice.

• cut_frame (Transform) – defines the plane used to slice the TargetMesh.

• options (GeometryScriptMeshPlaneSliceOptions) – selects additional clean-up operations performed after the cut.

• debug (GeometryScriptDebug)

Return type:

DynamicMesh

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

Mesh-Boolean-Union an object with itself to repair self-intersections, remove floating geometry, etc.

Parameters:

• target_mesh (DynamicMesh)

• options (GeometryScriptMeshSelfUnionOptions)

• debug (GeometryScriptDebug)

Return type:

DynamicMesh
