Detailed Description

Perspective and ray generating functions.

Constructor & Destructor Documentation

inline

Sets perspective for output image.

Camera location, subject, viewport, field of view, focus and aperture can be adjusted.

Example:

Camera(dimensions, Vector3D(5,0,0));

virtual

For each pixel sample, create a ray using a given x and y value, mapped from the camera to the target.

Example:

    GetRay(x, y);

static Vector3D Camera::RandomInUnitDisk ( )

inlinestatic

Returns a random vector with a dot product greater than 1.0.

Example:

RandomInUnitDisk();
