i want to generate a bezier curve pass through several points i input by mouse.These points are more than four,can anyone help me and give me some suggestions about how to implent it?
More thanks.
Good luck!
You have to solve the distance between points along the curve first to get your u & v.
Generally, the shortest arc lengths between points approx. the best curve.
p0 and p3 are the endpoints; f and g are two points along the curve.
d1 is distance between p0 and f; d2 between f and g; d3 between g and p3.
Solving for control points, p1 and p2:
Let u=d1/(d1+d2+d3); v=(d1+d2)/(d1+d2+d3)
This is where I link you to:
