Single/DoubleSlit Experiment

By Kian Akhavain

Project Description

My final project for CPE 471 was to create the single slit and double slit experiment. I tried to make an interesting and nearly accurate portrayal of how electrons line up when you shoot then out of a cannon through a single slit and double slit.

Project Implementation

The project implementation began with our previous camera project and adding new pieces from there.

• Used the user input to determine where the camera was facing.


• A simple scene with walls was built, then electrons are "fired" from a source point through the walls in a fashion that follows a parabolic curve (not physically accurate). The hard part came from making the patterns that looked similar to thing singleslit and doubleslit experiment outcomes. The patters are the interference patter and the single slit pattern.


• The most difficult aspect of the project was designing the program to allow postprocessing effects. Adding an extra framebuffer and then editing that frame buffer to include a bunch of different post processing effects was all new concepts to me that were not gone over in class. Completing the extra framebuffer allowed me to add a ton of different post processing effects including blur, sharpen, greyscale, negative, and sobel.
