crazyspace_init_object_for_eval()

static void crazyspace_init_object_for_eval ( struct Depsgraph *  depsgraph, Object *  object, Object *  object_crazy  )

static

Crazy-space evaluation needs to have an object which has all the fields evaluated, but the mesh data being at undeformed state. This way it can re-apply modifiers and also have proper pointers to key data blocks.

Similar to BKE_object_eval_reset(), but does not modify the actual evaluated object.
