Detailed Description

Functor that computes view matrix every frame.

Logical views are composed with a View and a Viewpoint object. Viewpoint is a functor containing an algorithm to compute the view matrix which is called before rendering a new frame. This composition can be changed dynamically using View::SetViewpoint() to allow switching to different view modes (first-person, chase-plane, etc). Despite the view appearing to change, View keeps the same underlying osg::Camera object.

Viewpoint is capable of controlling first-person and chase-plane views by converting the player's matrix into an eye matrix. View/Viewpoint supercedes EyeCraft and ChasePlane of old versions.
