public static Matrix4x4 TRS (Vector3 pos, Quaternion q, Vector3 s);

描述

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。

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; } }
