Frosted Glassin Path Tracing RendersJust some frosted glass from a microfacet transmission model, see the associated entry for details. |

Spectral Cornell Boxin Path Tracing RendersThis Cornell Box was rendered spectrally, using actual light wavelengths instead of binning everything in RGB channels. Note there was little point in rendering this spectrally, since the dependence on wavelength was not very c...  spectral

More HDR-based causticsin Path Tracing RendersSome more caustics, rendered by GPU. |

HDR Causticsin Path Tracing RendersThis was rendered on my GPU. It shows a scene consisting of four glass spheres (with increasingly high refractive indices) lit by a low-resolution HDR image (image-based lighting). The spheres exhibit fresnel reflection. The fl... |

More GPU path tracingin Path Tracing RendersSome more path tracing using the GPU. I added textures! I need to implement HDR texturing with tonemapping, otherwise the sky appears way too bright. |

GPU-rendered Cornell Boxin Path Tracing RendersThis is the product of an attempt at using OpenCL for path tracing. It is extremely high quality, and is in standard, non gamma-corrected form (so you might want to adjust the gamma of the render to make it look more realistic)... |

HD Buddhain Path Tracing RendersThis Happy Buddha model has, believe it or not, a little over one million triangles. I used my anisotropic "metal" material on it, so it's not exactly lambertian diffuse but close. The hints of green and blue in the... |

Glass cylinderin Path Tracing RendersThis was done a long time ago, back when I added the basic cylinder primitive. It shows a simple cylinder along with a refractive material, exposed to a light source. I am not sure why the black stuff on the top of the cylinder... |

Photorealistic Tablein Path Tracing RendersMy first attempt at photorealism. It is decent but I was expecting better. I need to smooth the normals and get a better table model (as well as some kind of lamp model, because having a big off-screen light quad just doesn... |

Dragonsin Path Tracing RendersA more complicated scene, using a very high-poly dragon (100k triangles). Instancing was not implemented at the time of this render, so there are, in fact, about 300k triangles in this scene. Several light sources are present i... |

Reflective Causticin Path Tracing RendersShows the caustics formed by a reflective object concentrating reflected light onto a caustic envelope. Note that there is no cusp singularity because the light source is not infinitely far away (and has an area). |

|
Pyramidin Path Tracing RendersA bunch of spheres arranged in a pyramidal fashion, inside the same Cornell Box. Most of the spheres and either specular or refractive, but the middle row has two types of materials, plastic and metal (both red). Note that the... pyramid

Standard Cornell Boxin Path Tracing RendersYour standard Cornell Box with a specular sphere and a refractive (dieletric glass) sphere. Caustics are present and the box's walls are properly shaded according to a diffuse (lambertian) distribution. |
