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

## Description

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;
}```
