3D贝塞尔曲线C#实现

项目里面使用的，在网上找的代码，感谢贡献者，非常好用

public static Vector3 CalculateBezierPoint(float t, Vector3 p0, Vector3 p1, Vector3 p2, Vector3 p3)

{

float u = 1 - t;

float tt = t*t;

float uu = u*u;

float uuu = uu * u;

float ttt = tt * t;



Vector3 p = uuu * p0; //first term

p += 3 * uu * t * p1; //second term

p += 3 * u * tt * p2; //third term

p += ttt * p3; //fourth term



return p;

}
