Deferred Shading

Soft Shadow

Image Based Lighting

Lights come from the texture surrounding the scene. The warm and bright part of the texture light the front side of the model while the back is darker.  Images are diffuse only, specular with low PDF, specular with high PDF separately.

Ray Tracing & IBL

This is another IBL project, but with ray tracing algorithm. Left sphere showing lights pass through it while the other sphere is reflecting the whole scene. Second image applied depth of field.

Ambient Occlusion

Implemented Alchemy Screen-Space Ambience Obscurance algorithm. Ambient occlusion factor at each pixel is approximated by points within specified range.
