which part of the code is responsible for the rotation in this example? Is it the camera or the scene itself?

in the render function, you have

function render() {

    var timer = Date.now() * 0.0001;

    camera.position.x = Math.cos( timer ) * 200;
    camera.position.z = Math.sin( timer ) * 200;
    camera.lookAt( scene.position );

renderer.render( scene, camera );

}

That makes the camera take a circular path of radius 200 , always looking at the center of the scene

all this should be in a rotate function or something.. var timer = Date.now() * 0.0001; camera.position.x = Math.cos( timer ) * 200; camera.position.z = Math.sin( timer ) * 200; –  expiredninja Jun 7 at 17:37

Yes, it would have been more clean in a function. May be the apropiate name would be updateCameraPosition –  vals Jun 9 at 16:47

According to the source they call the render method and it simply updates the camera position and uses camera.lookAt() to calculate the matrix to look at the center.

I was thinking the same thing, but could you be more specific about where that happens? –  expiredninja Jun 2 at 4:43
