  1. POHow to return all points along a bezier curve?
    text
    copied!<p>I posted a previous question about generating a bezier curve based on only the start and end points, and I was able thanks to the answers in that create a bezier curve using the information I have.</p> <p>This is the code that allows me to draw the types of curve that I want on a form.</p> <pre><code>private void Form1_Paint(object sender, System.Windows.Forms.PaintEventArgs e) { Random rnd = new Random(); Point startp = new Point(rnd.Next(0, this.Width), rnd.Next(0, this.Height)); Point endp = new Point(rnd.Next(0, this.Width), rnd.Next(0, this.Height)); int xMod = 0; int yMod = 0; if (startp.X &gt; endp.X) { xMod = -1; } else { xMod = 1; } if (startp.Y &gt; endp.Y) { yMod = 1; } else { yMod = -1; } Point control1p = new Point(endp.X + (rnd.Next(20, 50) * xMod), endp.Y + (rnd.Next(20, 50) * yMod)); Point control2p = new Point(endp.X + (rnd.Next(5, 20) * xMod), endp.Y + (rnd.Next(5, 20) * yMod)); Point[] pts = { startp, control1p, control2p, endp }; Pen dashed_pen = new Pen(Color.Black, 0); dashed_pen.DashStyle = Drawing2D.DashStyle.Dash; for (int i = 0; i &lt;= 2; i++) { e.Graphics.DrawLine(dashed_pen, pts(i), pts(i + 1)); } e.Graphics.SmoothingMode = Drawing2D.SmoothingMode.HighQuality; Pen bez_pen = new Pen(Color.Black, 3); e.Graphics.DrawBezier(bez_pen, pts(0), pts(1), pts(2), pts(3)) } </code></pre> <p>Is there a way, or can someone help me with returning all the points that form the curve? I'd like for each point of a curve calculated from those points to be returned in an array of points, but I'm having no luck figuring it out, and haven't been able to find a similar solution on stackoverflow or google in general.</p> <p>Thanks.</p>
