SciroccoXCoding's questions

我尝试使用 .NET 中的 System.Numerics 库围绕轴 (Y) (0,1,0) 以特定角度 (90°) 旋转矢量 (0,0,-1)

我的问题是我得到了错误的输出，我没有得到问题所在。代码的输出是：原始向量：<0 0 -1> 旋转向量：<-0,99999994 0 -5,9604645E-08>

如果我将矢量 (0,0,-1) 绕 (0,1,0) 旋转 990 度，则输出应为(-1,0,0)

using System.Numerics;

class Program
{
 static void Main()
    {

        Vector3 vector = new Vector3(0,0,-1);
        Vector3 rotateAxis = new Vector3(0,1,0);
        float angle = 90;

        //Create Radians
        float radians = (float)(angle *Math.PI/180);

        Quaternion rotation = Quaternion.CreateFromAxisAngle(rotateAxis, radians);

        // Rotate Vector
        Vector3 rotatedVector = Vector3.Transform(vector,rotation);

        Console.WriteLine($"Original vector: {vector}");
        Console.WriteLine($"rotated vector: {rotatedVector}");
    }
}
