Allows to perform correction of coordinate delta/displacement in a
similar way of how sculpt mode handles sculpting on a deformed mesh.
An example of usecase of this is allowing riggers and sciprters to
improve corrective shapekey workflow.
The usage consists of pre-processing and access. For example:
object.crazyspace_eval(depsgraph, scene)
# When we have a difference between two vertices and want to convert
# it to a space to be stored, say, in shapekey:
delta_in_orig_space = rigged_ob.crazyspace_displacement_to_original(
vertex_index=i, displacement=delta)
# The reverse of above.
delta_in_deformed_space = rigged_ob.crazyspace_displacement_to_deformed(
vertex_index=i, displacement=delta)
object.crazyspace_eval_clear()
Fuller explanation with actual usecases and studio examples are written in
