Nice one Peter, I didn't think of that lol... Had target objects created from vertices, sceneX,Y,Z etc etc but didn't do that lol
I have updated url using your suggestion... Just don't drag rotate the sphere or it's chaos. http://www.allforthecode.co.uk/development/away3d/lookat_point_on_sphere/ <http://www.allforthecode.co.uk/development/away3d/lookat_point_on_sphere/> Now to: 1. Work out if possible to prevent HoverCamera3D from zooming away from the object when looking at the top or bottom. 2. Work out translation of click location with HoverCamera3D pan and tilt angles.
