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.

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

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.
