Utilities & Constants

utils

hazy.utils.all_same_type(objects: Iterable) → bool

Check if all objects in iterable have the exact same type.

Parameters:

objects – Iterable of objects to check

Returns:

True if all objects have identical type, False otherwise

Raises:

ValueError – If iterable is empty

hazy.utils.check_same_frame(*objects: GeometricPrimitive)

Verify that two geometric primitives are in the same reference frame.

Parameters:

• object1 – First geometric primitive

• object2 – Second geometric primitive

Raises:

RuntimeError – If objects are in different frames
