virtual void NL3D::UCamera::setFrustum (  float    width,
float    height,
float    znear,
float    zfar,
bool    perspective = true
)  [pure virtual]
 

Setup the camera mode as a perspective/ortho camera. NB: znear and zfar must be >0 (if perspective).

Implemented in NL3D::CCameraUser.

virtual void NL3D::UCamera::setFrustum (  float    left,
float    right,
float    bottom,
float    top,
float    znear,
float    zfar,
bool    perspective = true
)  [pure virtual]

)  [pure virtual]
 

Setup a perspective camera, giving a fov in radians.

Parameters:
fov  the horizontal angle of view, in radians. (Pi/2 as example)
aspectRatio  the ratio horizontal/vertical (1.33 as example).
znear  the front clipping plane distance.
zfar  the back clipping plane distance.

Implemented in NL3D::CCameraUser.
