Represents a mapping from the 3D scene onto the final image. A camera lens is
responsible for determining what ray to cast through each pixel.

getRay
Ray getRay(float x, float y, int imageWidth, int imageHeight, double lensX, double lensY, double time) Create a newray
to be cast through pixel (x,y) on the image plane. Two sampling parameters are provided for lens sampling. They are guarenteed to be in the interval [0,1). They can be used to perturb the position of the source of the ray on the lens of the camera for DOF effects. A third sampling parameter is provided for motion blur effects. Note that theCamera
class already handles camera movement motion blur. Rays should be generated in camera space - that is, with the eye at the origin, looking down the -Z axis, with +Y pointing up.- Parameters:
x
- x coordinate of the (sub)pixely
- y coordinate of the (sub)pixelimageWidth
- image width in pixelsimageHeight
- image height in pixelslensX
- x lens sampling parameterlensY
- y lens sampling parametertime
- time sampling parameter- Returns:
- a new ray passing through the given pixel
