Member Function Documentation

degToRad()

float Camera::degToRad ( float  deg )

staticprotected

A helper method which converts degrees to radians.

Parameters

deg	The number of degrees.

Returns

The number of radians.

generateRay()

virtual Ray MobileRT::Camera::generateRay ( float  u, float  v, float  deviationU, float  deviationV  ) const

pure virtual

Generates a ray with the origin in the camera.

Parameters

u	u = x / width
v	v = y / height
deviationU	deviationU = [-0.5F / width, 0.5F / width]
deviationV	deviationV = [-0.5F / height, 0.5F / height]

Returns

The new generated ray.

Implemented in Components::Orthographic, and Components::Perspective.

getAABB()

AABB Camera::getAABB ( ) const

virtual

Calculates the bounding box of the camera.

Returns

The bounding box which surrounds the camera.

Reimplemented in Components::Orthographic.
