This program is a very simple raytracing application made using OpenGL. The core libraries used are GLEW, GLFW, and GLM.
The project uses CMake to build. Running the CMake GUI application and selecting the project's root directory, ie. <location>/RayTracer/ as the source code location, and <location>/RayTracer/build as the build location, and then running configure and generate allows the user to create visual studio project files for the project. After these files are generated, the program can be opened in visual studio by opening the RayTracer.sln project file. To build the program in visual studio, right click the 'RayTracer' project inside the solution hierarchy in visual studio and select Set as startup project. Finally, right click the 'RayTracer' project, select properties, and in the 'Configuration Properties >> Linker >> Input' section, add glew32s.lib to the 'Additional Dependencies' field. Now the project can be recompiled by pressing F7 or selecting 'Build >> Build Solution' in Visual Studio.
