rotation

gistfile1.txt

Я сделал поворот в v3 со следующим кодом:

<canvas id="carcanvas" width="1" height="1"></canvas>


    if (document.getElementById('carcanvas').getContext) {
        var supportsCanvas = true;
    } else {
        var supportsCanvas = false;
    }

    var rImg = new Image();
    rImg.src='/images/cariconl.png';

    // Returns the bearing in radians between two points.
    function bearing( from, to ) {
        // Convert to radians.
        var lat1 = from.latRadians();
        var lon1 = from.lngRadians();
        var lat2 = to.latRadians();
        var lon2 = to.lngRadians();
        // Compute the angle.
        var angle = - Math.atan2( Math.sin( lon1 - lon2 ) * Math.cos( lat2 ), Math.cos( lat1 ) * Math.sin( lat2 ) - Math.sin( lat1 ) * Math.cos( lat2 ) * Math.cos( lon1 - lon2 ) );
        if ( angle < 0.0 )
            angle  += Math.PI * 2.0;
        if (angle == 0) {angle=1.5;}
        return angle;
    }

    function plotcar() {
        canvas = document.getElementById("carcanvas").getContext('2d');
        var cosa = Math.cos(angle);
        var sina = Math.sin(angle);
        canvas.clearRect(0,0,32,32);
        canvas.save();
        canvas.rotate(angle);
        canvas.translate(16*sina+16*cosa,16*cosa-16*sina);
        canvas.drawImage(rImg,-16,-16);
        canvas.restore();
    }
и в методе анимации:

if (supportsCanvas) {
                    angle = bearing(new google.maps.LatLng(lat1, lng1),new google.maps.LatLng(lat2, lng2));
                    plotcar();
                }
Я надеюсь, что помощь.
