Raytracer in C++

#This document is a WIP

This document is still a work in progress.

Update 0.1

So far, this raytracer has the following abilities:

1. You can add shapes like spheres, Axis Aligned Bounding Boxes(AABBs), discs or planes in your scene. Add a new object in initializeObjects() method inside main.cpp.

2. You can add two types of lights, point lights and directional lights. You can have as many lights as you want in the scene. Add a new light in initializeLights() method inside main.cpp.

3. The camera is modeled as a perspective camera, so you can change its position and lookat.

4. Anti-aliasing is disabled by default. To enable anti-aliasing, use useSampling method of the Camera class.

Update 0.2

1. Triangle shape has been added.

2. Now you can create multiple test scenes and have objects particular to a scene. Previously, objects container was static and multiple scenes were not allowed. A scene has width, height, camera, objects and lights.

3. Transformations work. You can rotate, scale and translate objects.

4. Depth of field works.

5. Specular shading has been added. Remember: Specular coeff + diffuse coeff + ambience + reflectivity must be equal to 1.
