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
b   int or float: coordinate of second point on the curve
c   int or float: coordinate of third point on the curve
d   int or float: coordinate of fourth point on the curve
t   float: value between 0 and 1
