Ray Tracing: Depth Of Field
https://ray-tracing-conept.blogspot.com/2015/01/depth-of-field.html
1. Calculate the normal ray start and ray direction as we are calculating before. 2. Find the location of pixel on focal plane by placing 't' as focal length in ray equation. I call it as point Aimed. 3. Find the new Jitter-ed camera position as mentioned in the code below. 4.

A lot of effects that seem hard to achieve with other techniques are very natural using a raytracer. Reflection, refraction, depth of field, high quality shadows. Of course that doesn't necessarily mean they are fast. Graphics card on the other hand they generate the majority of images these days but are very limited at ray tracing.

"Jitter matrix" is a way of choosing points with a different random distribution, and you don't need it in order to make depth of field work - it's just a refinement you could add later. It's also applicable to any other situation where you …
Depth of Field – CS384G Computer Graphics Final Project
https://pathtracing.home.blog/depth-of-field/
Implementing depth of field in stochastic ray tracing consists of two parameters that influence out final image: Focal Length – determines how far objects must be from the camera to be in focus. Items closer than the focal point will be blurry, as will items farther away. Aperture – determines how blurry objects that are out of focus will appear.

Take a Linux shell and type the following command where your file lives: 001 c++ -O3 -o raytracer raytracer.cpp To create an image, run the program by typing ./raytracer in a shell. Wait a few seconds. When the program returns, you should have a file called untitled.ppm on your disk.
