This is my first, albeit small project I have worked on in a while, as I have been tied up with school. Thankfully now that Summer is here I can finally knuckle-down and get some work done 
The title is pretty self-explanitory, I hope. This is basically a project started so I could learn about the mathematics and practice the implementation of Raycasting, I am following This excellent article by F. Permadi : http://www.permadi.com/tutorial/raycast/index.html
As the title also suggests, I am new to the realm of Raycasting, so any suggestions or help you could provide would be most appreciated 
If you too are new to raycasting, please feel free to ask any questions as to how I went about implementing it in this little demo
Controls : WASD to move, Q and E to rotate view
PS : I am aware of the ‘flashing white screen’ observed while moving, The way I achieve rendering in this project is, every time the player’s position/rotation changes, to use 3D maths to calculate a 1-dimensional int array of length (window_width * window_height) which will act as a ‘pixel-buffer’, update an image using the pixel buffer and use the Component.repaint() to re-draw the image(which is streched accross the window). This probably isn’t the best way to render, but if anyone can suggest a better way, please let me know and I will see if I can implement it
[EDIT]
nvm, its fixed now
