The camera look in his local Y direction (see CScene). No observer is provided, since a camera: has default behavior of a transform. can't be clipped (well... :) ). is not lightable is not renderable Author(s): Lionel Berenguier , Nevrax France Date: 2000 Definition at line 56 of file camera.h.

(default is false). see setPerspective(). znear and zfar are kept from previous setup. NB: as setPerspective(), fov is the full horizontal angle of camera (in radians). Definition at line 91 of file camera.h. bool NL3D::CCamera::enableTargetAnimation ( bool en ) [inline]   enable Target/Roll animation. (default is false). TTransform mode is forced to RotQuatMode. Roll is forced to 0. The camera builds the rot matrix from the animated target/roll. Definition at line 100 of file camera.h.
