Texture | Chevron texture | Composite texture | Groove texture | Circular texture |
|---|---|---|---|---|
Equation | f(x) = P1·x2 + P2·x+ P3 | f(x) = P1·x2 + P2·x+ P3 | f(x) = P1·x2 + P2·x+ P3 | f(x) = P1·x2 + P2·x+ P3 |
P1 | − 9.52 | − 5.146 | − 6.904 | − 15.90 |
P2 | 8.377 | 6.462 | 6.942 | 16.06 |
P3 | 1.791 | 0.7071 | − 0.2811 | − 0.2623 |
R-square | 0.946 | 0.912 | 0.8769 | 0.8741 |
