how to set camera fov and zoom? model looks like unnormal!

view.camera.lens = new PerspectiveLens(60).

That should give you a perspective lens with VERTICAL fov of 60 degrees.
Then you can change the fov like

(view.camera.lens as PerspectiveLens).fieldOfView = 54;

Making the fov smaller has the effect of zooming. Otherwise you will have to dolly the camera (move it in and out!)

I stress the vertical because I once waisted a whole afternoon trying to match with a photograph before realising :O)

Good Luck!
