Constructor & Destructor Documentation

OrthographicCamera()

OrthographicCamera ( Film & film, const Vec3R & rotation = Vec3R(0.0), const Vec3R & translation = Vec3R(0.0), double frameWidth = 1.0, double nearPlane = 1e-3, double farPlane = std::numeric_limits<double>::max() )

inline

Constructor.

Parameters

film	film (i.e. image) defining the pixel resolution
rotation	rotation in degrees of the camera in world space (applied in x, y, z order)
translation	translation of the camera in world-space units, applied after rotation
frameWidth	width in of the frame in world-space units
nearPlane	depth of the near clipping plane in world-space units
farPlane	depth 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.

getRay()

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

inlineoverridevirtual

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.

lookAt()

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

inlineinherited

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.
