Name

### curvePoint()

Examples ```curve(5, 26, 5, 26, 73, 24, 73, 61);
curve(5, 26, 73, 24, 73, 61, 15, 65);
ellipseMode(CENTER);
int steps = 6;
for (int i = 0; i <= steps; i++) {
float t = i / float(steps);
float x = curvePoint(5, 5, 73, 73, t);
float y = curvePoint(26, 26, 24, 61, t);
ellipse(x, y, 5, 5);
x = curvePoint(5, 73, 73, 15, t);
y = curvePoint(26, 24, 61, 65, t);
ellipse(x, y, 5, 5);
}```
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.
Syntax
`curvePoint(a, b, c, d, t)`
Parameters
a int or float: coordinate of first point on the curve int or float: coordinate of second point on the curve int or float: coordinate of third point on the curve int or float: coordinate of fourth point on the curve float: value between 0 and 1
