Matrix4x4.TRS

Description

创建平移、旋转和缩放矩阵。

返回矩阵是这样一个矩阵：它将对象置于位置 pos 处， 按旋转 q 进行定向，并且按 s 进行缩放。

using UnityEngine;
using System.Collections;

public class ExampleClass : MonoBehaviour {
    public Vector3 translation;
    public Vector3 eulerAngles;
    public Vector3 scale = new Vector3(1, 1, 1);
    private MeshFilter mf;
    private Vector3[] origVerts;
    private Vector3[] newVerts;
    void Start() {
        mf = GetComponent<MeshFilter>();
        origVerts = mf.mesh.vertices;
        newVerts = new Vector3[origVerts.Length];
    }
    void Update() {
        Quaternion rotation = Quaternion.Euler(eulerAngles.x, eulerAngles.y, eulerAngles.z);
        Matrix4x4 m = Matrix4x4.TRS(translation, rotation, scale);
        int i = 0;
        while (i < origVerts.Length) {
            newVerts[i] = m.MultiplyPoint3x4(origVerts[i]);
            i++;
        }
        mf.mesh.vertices = newVerts;
    }
}
