Ray Casting

Simple ray casting simulation that shows how rays of light would behave depending on its source location and the walls around it

Note: This version requires Visual Studio. If you do not have access to Visual Studio, here is a version for linux and windows that requires no setup: https://github.com/Zachhi/RayCasting-Windows-Linux

Demo

(Quality much worse here due to gif-conversion)

Watch the video here (above is only a 10 second gif): https://www.youtube.com/watch?v=ngBwJ4v9c_M

Controls

• Click twice to draw a wall from the first click to the second click
• "C" to clear all walls
• Move mouse around to change light source position
• "Space" to change the source type. 3 Types: Draw all the light rays Draw only the light rays that hit walls Draw no light rays
• "Up arrow" to increase amount of light rays
• "Down arrow" to decrease amount of light rays
• "Escape" to exit the program

Dependencies

• Windows
• Visual Studio 19 or above
• SFML (Simple and Fast Multi-Media Library) 2.5.1 or later is required in order to run this program. You can install SFML here: https://www.sfml-dev.org/download/sfml/2.5.1/
• Since we are using Visual Studio, download the Visual c++ 15 from the sfml website

If you don't have access to Visual Studio, or are on linux, scroll to the top to find the other version

Installing and Executing

• Download the source code from github, or clone the repository into Visual Studio
• Import into Visual Studio
• Build according to your need (x86 or x64)
• In project settings
  • Add the /path/to/sfml/include to your c++ include path
  • Add the /path/to/sfml/libray to the linker library path
  • Link the following sfml libraries: sfml-graphics.lib, sfml-windows.lib, sfml-system.lib, sfml-audio.lib
  • Link the following debug libraries: sfml-graphics-d.lib, sfml-windows-d.lib, sfml-system-d.lib, sfml-audio-d.lib
  • Copy the sfml dlls (in the sfml/bin folder) to your project folder
• If that is too hard to follow, a simple 5 minute tutorial for linking SFML with a Visual Studio project can be found here: https://www.youtube.com/watch?v=YfMQyOw1zik
• Click the run button at the top and the program should start

If you would prefer not having to link libraries, and would prefer a version fully set up, see the link at the top
