Matrix4x4.TRS

Parámetros

Descripción

Creates a translation, rotation and scaling matrix.

The returned matrix is such that places things at position pos, oriented in rotation q and scaled by s.

	// Translate, rotate and scale a mesh. Try varying
	// the parameters in the inspector while running
	// to see the effect they have.
	
	var translation: Vector3;
	var eulerAngles: Vector3;
	var scale = Vector3(1, 1, 1);
	
	
	private var mf: MeshFilter;
	private var origVerts: Vector3[];
	private var newVerts: Vector3[];
	
	
	function Start () {
		// Get the Mesh Filter component, save its original vertices
		// and make a new vertex array for processing.
		mf = GetComponent.<MeshFilter>();
		origVerts = mf.mesh.vertices;
		newVerts = new Vector3[origVerts.Length];
	}
	
	
	function Update () {
		// Set a Quaternion from the specified Euler angles.
		var rotation = Quaternion.Euler(eulerAngles.x, eulerAngles.y, eulerAngles.z);
		
		// Set the translation, rotation and scale parameters.
		var m = Matrix4x4.TRS(translation, rotation, scale);
		
		// For each vertex...
		for (var i = 0; i < origVerts.Length; i++) {
			// Apply the matrix to the vertex.
			newVerts[i] = m.MultiplyPoint3x4(origVerts[i]);
		}
		
		// Copy the transformed vertices back to the mesh.
		mf.mesh.vertices = newVerts;
