CS 6620 - Fall 2019 - Ray Tracing for Graphics

Project 9 - Depth of Field

In this project we add depth of field support to our ray tracers.


XML Scene Format

In the XML scene format we specify depth of filed using the "dof" and "focaldist" tags inside the "camera" tag as below.

   <!-- Additional camera parameters -->
   <focaldist value="70.0"/>
   <dof value="1.5"/>

The "dof" value specifies the size of the circle of confusion and "focaldist" is the distance from the camera to the focal point.
