nearPlanedepth of the near clipping plane in world-space units
farPlanedepth of the far clipping plane in world-space units

If no rotation or translation is provided, the camera is placed at (0,0,0) in world space and points in the direction of the negative z axis.

math::Ray<double> getRay ( size_t  i,
size_t  j,
double  iOffset = 0.5,
double  jOffset = 0.5 
) const

Return a Ray in world space given the pixel indices and optional offsets in the range [0, 1]. An offset of 0.5 corresponds to the center of the pixel.

Implements BaseCamera.

void initRay ( double  t0,

void lookAt ( const Vec3R xyz,
const Vec3R up = Vec3R(0.0, 1.0, 0.0) 

Rotate the camera so its negative z-axis points at xyz and its y axis is in the plane of the xyz and up vectors. In other words the camera will look at xyz and use up as the horizontal direction.
