Photon Mapping

In this project we will replace path tracing for indirect illumination with photon mapping.

Result

Only Indirect

• 32 Path Tracing Sample count (For rendering time)
• Photon number: 1M caustic num:100k
• Search Radius: 0.5, max number: 500
• With glossy refraction and reflections
• 4-5 mins render time

Direct and indirect

Time: 2:48s
