| Description | Evalutes the curve at point t for points a, b, c, d. The parameter t varies between 0 and 1, a and d are points on the curve, and b and c are the control points. This can be done once with the x coordinates and a second time with the y coordinates to get the location of a curve at t. | ||||||||||
