Erector Set Crane. Erector set parts was ray traced using POV 2.2 on a Mac II ci with an Applied Engineering Transwarp 40 MHz 68040
Accelerator and 20 Mb Ram. All calculations and coding were done by hand.

Dutch Interior, after Vermeer. This image was inspired by the work of the 17t century Dutch painter, Jan Vermeer, whose sensitivity to the interplay of light and surfaces helped to give his painting a dramatic effect. The radiosity method was used to compute the global diffuse illumination during a view independent preprocess. After the view was determined, a Z-buffer based algorithm similar to distributed ray tracing was used to compute the specular reflection on the marble floor.

Simulated steel mill. The image was created using a modified version of the hemicube radiosity algorithm, computed on a VAX 8700 and displayed on a Hewlett Packard Renaissance Display. The environment consists of approximately 55,000 elements.

Eric's Office rendered with progressive-refinement hemicube radiosity algorithm; 500 patches, 7000 subpatches. Estimated ambient radiosity added. Computing and displaying each iteration took about 15 seconds on an HP 9000 Model 825 SRX.

(a) 1 iteration.

(b) 2 iterations.

(c) 24 iterations.

(d) 100 iterations.

Dani's Room. This image was rendered by Dani Lischinski, Filippo Tampieri, and Donald P. Greenberg for the 1992 paper Discontinuity Meshing for Accurate Radiosity. The image depicts a scene that represents a pathological case for traditional radiosity images, many small shadow casting details. Notice, in particular, the shadows cast by the windows, and the slats in the chair.

Nave of Chartres cathedral rendered with progressive-refinement radiosity algorithm, using ray tracing to compute form factors. Two bays, containing 9916 polygons, were processed and copied thre more times. Sixty iterations took 59 minutes on HP 9000 Model 835 TurboSRX.
