Ray Tracing Using JAVA

Abstract

To develop a platform for ray tracing where we create a scene using a text file and then our java application will create a realistic image of the scene. Description: Ray tracing is a technique to produce a realistic image virtually. This method converts a 3 dimensional image to 2 dimensional image to make it suitable for display on the computer screen. Ray tracing takes a lot of time in rendering the image, so it makes this technique suitable for applications where image can be generated before its actual use, for example television animation. In this project I have developed a Java application for ray tracing in which we define a scene in a text file. This text file serves as an input to the application which then decodes this scene into the various individual objects and lights. Then we take a simple camera as our viewer that defines our image plane. We render the continuous image pixel by pixel by shooting a ray from each pixel to the image plane and then we check for the intersections. Finally we calculate the colour at that pixel and display it.
