Software Ray tracing based on Ray Tracing by The Cherno.

Initially, Ray Tracing in One Weekend series was followed but it was not good enough for real time application . It is a good resource nonetheless and was very helpful for setting up material system without pre-requisite knowledge about the subject matter.

• Multithreading is supported but it can peak cpu usage by saturating the available cpu cores.
• Three types of materials are supported: Lambertian, Metal and Dielectric.
• The name for their base/solid color is called as Albedo.
• Lambertian has most roughness and are non metallic.
• Metals can have roughnesses that dictate the amount of scatter they produce when a light ray hits the surface.
• Dielectric material can reflect and refract light. They let light pass through them and have concepts like Total Internal Reflection. Typically, a change in medium occurs so a refractive index is needed. FresnelSchlick approximates whether reflection or refraction can occur.
• Another subtype of materials is called Emissivity which means that objects can emit their own light instead of relying on sky color for contribution in lighting the scene.

• GLFW
• Glad (gl 3.3, OpenGL, Core profile)
• glm
• imgui (docking branch)

• CMake
• Visual Studio

• Open the project directory inside Visual Studio.
• Open the CMakelists.txt file located in the project folder and Ctrl+S. This will clone and build the dependencies.
• In case of CMake related issues, delete 'out' folder and try rebuilding.
