Crop in the zoom

Hi everyone

It appears like your viewing frustum is specified wrong. Read up on near and far viewing limits.

Constructor

PerspectiveCamera( fov : Number, aspect : Number, near : Number, far : Number )

fov — Camera frustum vertical field of view.
aspect — Camera frustum aspect ratio.
near — Camera frustum near plane.
far — Camera frustum far plane.

Play with third value…
