RGKrt

Photorealistic physically-based renderer I initially wrote for photorealistic graphics course and improved afterwards.

Main features:

Bidirectional path tracing

Uses efficient data structures

Multisampling using various sample generators

Depth of field

Various BRDFs built-in: Phong, Cook-Torr, Beckmann, GGX

Refractions, reflections, caustics

Areal (surface) lights

Environmental map support

Linearly Transformed Cosines

Supports bumpmaps and normal maps

Non-interactive runtime (batch processing)

Simple and transparent input file format

Preview mode, very basic support for animations

HDR output in openEXR format

Currently it runs only on Linux. Source code is available on Github.

RGKrt is written in C++14 and it uses assimp , png++ , glm , libjpeg , ctpl and openEXR libraries.
