Reveal the illustrative slices to bring a complete cell model into view. Turn it, decompose it into parts with the geodesic explode, then click a part to read its coordinate. Each coordinate is an authored label; it is not measured from the geometry. Perturb a part and a rule shifts its coordinate. This demonstrates the reading workflow on a stand-in. An MRI or tomography instrument would have to supply real slices for a specimen, and a forward simulation would require dynamics that are not integrated here. Illustrative: this is not an imaging device, and no reconstruction algorithm runs.
