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)
