# C++11 Ray Tracing / Marching Framework
This is a basic C++11 OpenGL viewer application running a ray tracing / marching kernel for each tile in a pool of worker threads. The purpose of this application is to be a test framework for some rendering ideas I plan to explore.
# Features
A basic rendering framework and a collection of different libraries.
* Point, ray and triangle with AABB intersection
* Two different ray / triangle intersection tests
* Triangle / line segment distance functions
* Ray / plane intersection
* Template classes for vectors and matrices with common computer graphics operations implemented
* OpenGL viewer with text rendering and frame limiter
* Ten runtime switchable test scenes
* Screenshot feature, writing of BMP images
* Ray generation for orthographic and perspective cameras
* Build-in Cornell Box scene
* Tiled, parallel, CPU writeable + OpenGL drawable frame buffer system
* 3D DDA based grid intersection accelerator
* Basic mesh processing pipeline (load from disk, transform, compute normals etc.)
* Sampling module supporting various Low Discrepancy Sequences / QMC methods
* Time helpers for logging and performance measurement
* Basic tracing / logging system
* Super-sampling
* Gamma correction
# Building
Compiling has no prerequisites aside from a C++11 ready Clang and GLUT. I tested with Apple's [command line development tools][devdownloads]. Building should succeed with a simple
