Unity软管Mesh代码生成

1. 新建一个GameObject，然后挂载脚本BezierPipe；
2. 新建GameObject (1)和GameObject (2)，position分别设置为（0,0，0）和（0,0，1）；
3. 将GameObject (1)和GameObject (2)拖入脚本BezierPipe中，如图所示；
4. 勾选上Update；
5. 场景中生成软管模型；

6. 创建材质球拖入MeshRenderer中；

    public Vector3 fromPoint;
    public Vector3 toPoint;

    public void CalculateDir()
    {
   
        fromDir = Quaternion.FromToRotation(Vector3.forward, controlPoint - fromPoint);
        toDir = Quaternion.FromToRotation(Vector3.forward, toPoint - controlPoint);
    }

    public bool IsStraight()
    {
   
        return fromDir == toDir;
    }
}

    {
   
        t = Mathf.Clamp01(t);
        float oneMinusT = 1f - t;
        return oneMinusT * oneMinusT * p0 + 2f * oneMinusT * t * p1 + t * t * p2;
    }
