We show that the relative volume between the polytopes and the zonotope is an inconsistency measures. Small polytope volume indicates bad consistency of the observations. ...
We explain how the shape and the volume of the polytope are related to the positioning geometry. We show that this assignment has to be interpreted with care. ...
The volume of the polytope indicates the inconsistency of the observations, i.e. if the volume of the polytope is small, the observations are inconsistent. ...

For this reason, we generalize the unbounding sphere and separating plane approach to unbounding quadrics [12] for any SDF. Our method consists of two steps. ...
First, the unbounding volumes had to be compactly stored, efficiently computed, queried, and intersected with, for which revolutions of conic sections were designed with specific coefficient functions. ...

according to the discrete-time dynamics (13) , the initial box of the state variables e.g., [x 0 ] = ([−0.5, 0.5], [3.5, 4] ) T rotates at every iteration with an angle, say θ = π 4 , and preserves its volume ...
For this reason, almost all approaches proposed in the literature [3, 9, 10, 11, 12, 14] attempt to compute a tight outer approximation of this reachable set. ...
