RayTracer

A simple ray tracer written from scratch in C++, with multicore support, customizable camera, attenuation, alpha-beta correction, reflection, shadows, and more!

Additional Contributions by @DerekMcBlane:

• Bug Fixes: Fixed false positive sphere intersections, and leaky reflections that bled through
• Infrastructure Improvements: Addition of test (gtest) and build systems (cmake)

Current Features

• Parallelized tracing algorithm using OpenMP
• Perspective, axis aligned camera with lookAt functionality
• Attenuation, specular, and diffuse lighting implemented via phong shading
• Material, Color, vector, and geometric primitives
• Fully modularlized tracing pipeline with Camera, Scene, FrameBuffer, virtual interfaces for shape and lighting primitives
• Self contained math libraries for interpolation, vector operations, and ray intersections
• Stopwatch for benchmarking

Features I'd Like to Add

High Priority

• YAML scene discription files
• Polygon meshes
• Softer shadows
• Refraction
• Scripting for creating animations

Nice to Haves (will add if time)

• Proper refraction with fresnels
• KD-trees for fast rendering and culling with tons of on screen-objects
• Radiance

Build & Run Instructions

#CMake on Unix Build: ./build.sh Build output goes to directory named after build type. Can pass build type as an argument (e.g. ./build.sh Debug) Run: ./Release/bin/App
