Figure 10

Panels on the left show the values for the intercepts for 338 shapes, plotted against (from top to bottom) Attneave’s complexity index, mean curvature, number of inflection markers, and the index of symmetry. Panels on the right show the size of the slope for these shapes against the same shape attributes. The complexity index does not have physical units. Curvature is specified in radians, counts are without units, and the Symmetry Ratio is specified as normalized spans from the central axes of the shapes.
