Path Tracer

University of Pennsylvania, CIS 561: Advanced Computer Graphics, Course project

Features :

• Normal Map

• Diffuse are light, point light, spot light, infinite light(Environment Map)

• Different materials (Metal, ChromMirror, glass, plastic, etc.)

• Acceleration : BVH / Kd-Tree

• Lens-based Camera

• Implicit Surface Rendering

• Photon Mapper (may take super longer time, but render converges quite well!)

• Volume Rendering

Rendered Images

• Volume Rendering :

  Original Photon Mapper render

  

  thin & thick white fog volume render

  

  final volume render we get

  

• Photon Mapper : Rainbow Box

  

• Implicit Surface Rendering using Ray-marching

  

  

  

• Lens-based Camera with Lens Radius = 1.0 , 5.0, 10.0

  

  

  

• Complex model rendered within just few minutes (general <10min depends on your computer)with BVH/Kd-Tree and more the 1 hour at least without it.

  900 ssp MIS Glass dragon (around 3min rendering time) / 900 ssp MIS Happy Buddha (around 4min rendering time)

  

• victory pose (Mirror Material)

  

• Glass cup and ball (Environment Map)

  

• AirJordan Jumpman (Glass Material + Environment Map)

  

• (This one actually a little bit light / uv problem, but I think it's a cool mistake)

  

• Mountains (Texture + Normal Map + Environment Map)

  

• Wahoo series

  

• Wahoo's War(several different color point lights)

  

• Evil Wahoo..(OK, it's just a light problem, too dark)

  

• Normal Map Comparision (left back wall with normal map, right without)

  

• TwoLights Cornell Box

  

• Veach scene with Naive and direct lighting integrator

  

• Glass Ball scene
