Same idea, map points and control points from one function to the other.

1. void setup()
2. {
3.   size(800, 800);
4.  
5.   noFill();
6.   beginShape();
7.   vertex(61, 189);
8.   bezierVertex(61, 189, 196, 63, 237, 162);
9.   bezierVertex(278, 261, 287, 272, 340, 246);
10.   endShape();
11.   fill(#FF0000);
12.   ellipse(61, 189, 10, 10);
13.   ellipse(237, 162, 10, 10);
14.   ellipse(340, 246, 10, 10);
15.  
16.   int steps = 10;
17.   fill(#00FF88);
18.   for (int i = 0; i <= steps; i++)
19.   {
20.     float t = i / float(steps);
21.     float x = bezierPoint(61, 61, 196, 237, t);
22.     float y = bezierPoint(189, 189, 63, 162, t);
23.     ellipse(x, y, 5, 5);
24.   }
25.  
26.   fill(#0088FF);
27.   for (int i = 0; i <= steps; i++)
28.   {
29.     float t = i / float(steps);
30.     float x = bezierPoint(237, 278, 287, 340, t);
31.     float y = bezierPoint(162, 261, 272, 246, t);
32.     ellipse(x, y, 5, 5);
33.   }
34. }

Used both the coordinates of vertext() and those of the bezierVertex() calls.

thanks!
