Fog
 

I would like to have fog on the main window but not for an added small window. Is there any way to disable fog only for the small window?

Unfortunately for your purposes, the level of fog is set for scenes and not windows. To work around this, you can have the small window look at a different scene. After you have created your small window, create a new viewpoint, set its scene, then tell your window to use the new viewpoint. If you want this scene to have the same 3D models as your original scene call .duplicate( sceneNumber ) on all objects you want to appear in the second scene.

It works fine. Thanks a lot!

BTW, could you set different alpha values of an object in different scenes? If not, is there any way to do something like that?

Call the .copy( viz.WORLD, sceneNumber ) method on objects that need their appearce to be different than the original. The copy method returns a new model object that you can modify while not affecting the original.

That's exactly what I wanted to do. Thank you!
