Hi there, gradually getting my project ported over from papervision, one minor problem I’ve yet to solve is that at the moment the view is distorted kind of like the opposite way to what a fisheye lense does, which in papervision I found was determined by the .zoom and .focus attributes. Just wondering how to alter the same sort of settings in away3d 4 ?

Okay, got it, need to define a lense for the camera:

Where the part in brackets is the fieldOfView - larger = wideangle

Hi Mr Margaret, thanks for posting the answer.

Okay, got it, need to define a lense for the camera:

camera.lens = new PerspectiveLens (30); 

Where the part in brackets is the fieldOfView - larger = wideangle

Nice tip, but what about if you want tween the fov using tweenlite?

I’ve tried to modify the original class of PerspectiveLens and LensBase to do that but it isn’t working.

TweenLite.to(camera.lens, 2, { lensFov(30) });

Any idea?

So, after we’ve initialized the lens - view.camera.lens = new PerspectiveLens(70) - how do we dynamically change the fov at a later point?

There is no:
view.camera.lens.fieldOfView etc..

Lucid,
Try to create new “PerspectiveLens” object for your camera, if you want to manually update them in runtime:

You dont need to create one, it gets created when you create the view.

Just cast it

//eg works in renderloop
PerspectiveLens(view.camera.lens).fieldOfView +=0.01

arrgh, sorry, how could I forget it… :(
(view.camera.lens as PerspectiveLens).fieldOfView = the_FOV_you_want

You are awesome! Thanks!
