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. Building should succeed with a simple

$ make

Not much to see, just the basic are in place.
