This project uses CUDA to do GPU acceleration of path tracing. Global illumination can be accomplished in real-time frame rates (~15 fps) at 640 x 480 on a nVidia GTX-480 for small scenes (such as the Cornell Box). Bigger scenes (10k+ triangles) can render at ~1fps varying on how the geometry is distributed.

In general, the images start off noisy, but the longer the path tracer is run, the smoother the image becomes.

• Triangles with support for vertex normals and UV textures
• Area lights and soft shadows
• Reflections and refractions
• Velocities
• Create and update the BVH in parallel
• Blur and median filter
• Specifiable amount of depth and passes (The path tracer can be 'converted' into a ray tracer by specifying a max depth of 1)
