Examples
This page shows some of the images I rendered with JaTrac when most of the bugs related to photon mapping and irradiance gradients were already fixed. Still, if you look carefully you can find some that were present: SPEs, boundary bias, antialiasing glitches etc. Most of these are fixed in current code, but I don't exactly feel like rerendering everything once again. ;)
Simple scene from Peter Shirley's set of GI test scenes. | Another scene from this set. | Comparison image from WinOSi rendered with density estimation (2.5M photons total, 1400 in the irradiance estimate). | The same scene rendered with final gathering pass. |
Cornell Box with one wall textured. | Cornell Box partially submerged. | Cornell Box similar to the photograph here. Most of visible differences is due to gamma correction being too low in JaTrac image. | Fun scene computed with pure ray tracing. Note non-illuminated shader on the red-white checkered ball. |
Really weird shader that modifes some properties of a glass-like material. | Atrium geometry rendered with pure ray tracing and fog effect. | Atrium geometry rendered with path tracing and strong Sun-like illumination (50 paths per pixel). | Slightly modified Atrium geometry rendered with photon mapping. |
An example of procedural object. The triangles do not actually exist, but are created on the fly, as rays move through the scene. |
