Path-Tracer

Multi-threaded path-tracer written in C++.

Code available on GitHub.

Inspired by Peter Shirley’s mini-book series Ray Tracing in One Weekend.

Details

• Developed with C++.
• Objects: spheres, planes and boxes.
• Materials: Lambertians, Dielectrics and Metals.
• Matrix transforms can be applied to any object.
• Area lights. Every object can be a light by having an emissive material.
• Camera positioning and aperture/focal distance (depth of field) simulation.
• Image and procedural textures.
• Normal mapping.
• Bounding volume hierarchy (AABB) for optimized scene traversal.
• Randomized super-sampling antialiasing.
• Image based-lighting through HDR light probes.
• Bloom post-processing effect to emphasize HDR rendering.
• Tone Mapping and sRGB/Gamma correction when outputing to a non-HDR format.
• Multi-threaded rendering, dividing the screen into chunks.
• Detailed render statistics feedback.
