我无法在我的3D图形引擎(java)中转换点

import org.apache.commons.math3.geometry.euclidean.threed.Vector3D;
import org.apache.commons.math3.linear.MatrixUtils;
import org.apache.commons.math3.linear.RealMatrix;

public class PointTransformation {
    public static void main(String[] args) {
        // 定义原始点的坐标
        Vector3D originalPoint = new Vector3D(1, 2, 3);

        // 定义转换矩阵
        RealMatrix transformationMatrix = MatrixUtils.createRealMatrix(new double[][]{
                {1, 0, 0},
                {0, 1, 0},
                {0, 0, 1}
        });

        // 进行点的转换
        Vector3D transformedPoint = transformationMatrix.operate(originalPoint);

        // 输出转换后的点的坐标
        System.out.println("转换后的点的坐标：" + transformedPoint);
    }
}
