Start by casting a ray like normal from the eye through the pixel out into the scene. Instead of intersecting it with objects in the scene, though, you just want to find the point on the ray for which the distance from the eye is equal to the selected focal distance. Call this point the focal point for the pixel.

Depth of Field. Another distributed ray tracing effect added to our project is the implementation of a finite depth-of-field. In order to properly parametrize this setting, a new command was added to the parser. dof focal_distance aperture_size sample_rays. The three parameters are a floating-point distance to the focal plane, a floating point “aperture size”, which is the scale factor for …

Right now so called "real-time ray tracing" is a very active field right now, as it's been seen as the next big thing that 3D 3. accelerators need to be accelerating.

Depth of Field and the Circle of Confusion (CoC) (Demers, 2004) [6] “Depth of field is the effect in which objects within some range of distances in a scene appear in focus and objects nearer or farther than this range appear out of focus”

This is exactly the same process as using the primary ray to find a colour, in basic ray tracing. After repeating this for a large number of secondary rays, the average of all those colours is the colour you assign to the pixel in question (you don't use the primary ray - its only purpose is generating the secondary rays).

It is implemented by perturbing the direction of the reflected ray by a small amount. First, an orthonormal base is created for the original reflection ray by making its smaller coordinate 1, and using cross products to find the ONB axes.
