CPU (soon to be GPU) RayTracer

Currently supports spheres, planes, triangles and boxes. I intend to add more objects such as triangle meshes at some point.

Inspired by RaytracingInOneWeekend, PBRT, and TheCherno RayTracing series

Usage

The main.cpp file provides an example of the usage of the RayTracer.

Scene Management

First create a Scene object, which holds the shapes and materials. Second, add shapes to the vector of shapes. For example: scene.Shapes.push_back(new Sphere({ 0.0, 0.0, -1.0 }, 0, 0)); where the first argument in the Sphere constructor is the position (Vector3), the second is the radius, and the third is the material index (next section). Third, add materials using scene.Materials.push_back(Material({ .Albedo = {0.3, 0.3, 0.8}, .Roughness = 0.1, .Metallic = 0.0 })). These materials are accessed using the material index passed to the shapes in their constructor, using zero-based indexing.
