Photon Mapping
Paul Solt and Lyndsey Whitman
Project Final Report and Documentation
Figure 1: Scene with Direct Illumination
Figure 2: 10000 Photons, 5 used in estimate
Figure 3: 100000 Photons, 1000 used in estimate
Figure 4: Reflection on the Wall with shadows
Figure 5: Refraction
Figure 6: Walls are reflective, yet still store some photons. 2x Multisampling. There are a few lines of artifacts.
Fixed a bug with an invalid Polygon which was part of the diagnol line artifact in the previous image.
Figure 7: Walls and floor are 0.7 reflective. 1000 photons, 50 used in estimate with range of 1.5 (101 seconds)
Figure 8: 10,000 photons, 300 used in estimate range 2.0 (104 seconds)
Visualizing the Photon Map
Figure 9: 10,000 photons. Range = 2.25 (Left or top) 100 used in estimate (Right) 600 used in estimate
Figure 10: 100,000 photons (Left) 1,000 used in estimate, range = 1.5 (Right) 10,000 used in estimate, range = 1.0
Figure 11: 10000 photons 300 used in estimate range 2.5 (86 seconds)
Figure 12: 10000 photons 300 used in estimate range 2.5 (100 seconds) / Direct Illumination on the Right side
Figure 13: 10000 photons 300 used in estimate range 2.5 (239 seconds) Multiple Reflections on./ Photon Irradiance Visualized
Figure 14: 10000 photons 300 used in estimate (41 seconds)
Figure 16: (8074 seconds) 100000 photons, 800 used in estimate, 2.0 range.
