Matrix4x4.TRS

Description

Creates a translation, rotation and scaling matrix.

The returned matrix is such that it places objects 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;
