classmethod approximate_convex_hulls_with_simpler_collision_shapes(simple_collision, approximate_options, debug=None) -> (simple_collision=GeometryScriptSimpleCollision, has_approximated=bool)

Attempt to approximate any convex hulls in the given simple collision representation. Updates the passed-in Simple Collision. Convex hulls that aren’t well approximated (to tolerances set in ApproximateOptions) will remain as convex hulls.

Parameters:
Returns:

simple_collision (GeometryScriptSimpleCollision): The collision in which to attempt to approximate the convex hulls

has_approximated (bool): Indicates whether any convex hulls were replaced with simpler approximations

Return type:

tuple

  • Add simple collision shapes from AppendCollision to CollisionToUpdate

Parameters:
Returns:

collision_to_update (GeometryScriptSimpleCollision):

Return type:

GeometryScriptSimpleCollision

classmethod compute_negative_space(mesh_bvh, negative_space_options, debug=None) → GeometryScriptSphereCovering
