PathTracer

Note: Work in progress

PathTracer is an attempt to create a real time GPU path tracing renderer, using CUDA. It currently uses SDL 2 to handle inputs and render window. The README will be updated as new features are implemented.

Installation

Prerequisite :

• Mac OS 10.9 or above
• Xcode and Xcode command line tools
• SDL 2 library
• CUDA LLVM Compiler (NVCC)

Simply run make, and launch ./pathtracer.

Current features

• Full CUDA kernel computation
• Real time camera movement
• Direct illumination
• Basic primitives
• Diffuse/Specular shading
• Fresnel reflection/refraction

Coming features

• Path tracing and global illumination (Color bleeding, etc)
• Data structure optimization
• Complex primitives / Meshes
• Texturing
• Antialiasing
• Depth of field
• Motion blur
• Caustics
• Animated scene

Controls

• W - Move forward
• A - Move left
• S - Move backward
• D - Move right
• Spacebar - Move up
• Left Shift - Move down
• Left Arrow - Rotate camera left
• Right Arrow - Rotate camera right
• Up Arrow - Rotate camera up
• Down Arrow - Rotate camera down
• K - Decrease FOV
• L - Increase FOV
• ESC - Quit
