Raytracer

Offline raytracing! Math! Oh My!

Overview

This raytracer is being made from guidance with The Ray Tracer Challenge from The Pragmatic Bookshelf.

TL;DR the book gives you defined test cases to pass and some general concepts. No copy pasting code from a book or tutorial here.

This is my attempt at the project, along with any extra features I decide to add on in the future.

Build Guide

This is my first attempt at using cmake since I wanted to use C++ for this particular project and wanted it to be crossplatform ish at best. but here's a quick run down tutorial of the set up:

1. In the root of the repository where CMakeLists.txt is located, run cmake -B<build directory location> to create a build of the project.
2. in the created build director run make to create the executable assuming you are running on a UNIX system.
3. run ./main in the terminal and boom you got yourself a program

Note: If you decide to generate a project for your favorite IDE, note that I built a majority of this project using Visual Studio's ability to manage CMake projects, so mileage may vary for other IDE's

Known Issues

• Tests only pass fully on MSVC compiler, GCC has a segfault when running gtest but the main program still works as intended as of October 2023, will get it passing on gcc at a later date

Milestone Images

images are created in the ppm file format then exported to jpg using GIMP

1. Printing a image to a screen using a progam to simulate a cannon shooting a projectile and recording the arc path
2. Printing a "clock" of pixels at 12 locations using matrix transformation definitions
   
3. Printing a unlit, unshaded sphere in 3D space
   
4. Printing a shaded, lit sphere using a basic Phong material
   
5. Printing a lit scene with no shadows
   
6. Printing a lit scene with shadows
