Figure 7:

A: Illustration of three layers of control points and with r = 0, 0.5, and 1 representing the meridional, isotropic, and circumferential region in the model, respectively. B: The three layers of control points were seeded across the scleral portions of the model. C: Contour plot showing the distribution of the region parameter r across the sclera. The mesh-free approach was used to approximate r across the scleral mesh. D: The first principal direction of the structure tensor (15) representing predominant fiber orientations. The mesh-free approach effectively approximated the circumferential and meridional fiber regions.
