An Application of Spectroscopy to Ray-Tracing Rendering

The following renders were created by Luxrender's Terrence Vergauwen based on the author's spectral distribution data (SPD) data found in The Double Amici Prism Spectroscope and on other data the author provided the Luxrender development team with. The conversion process can be summarized as follows:

The success of these renders can be ascertained by comparing them with actual photos of scenes illuminated by some of these lamps in The Author's Lamp Collection document. In the author's opinion, the renders on this page, easily cross the boundary between real and imaginary, hence they can justifiably be called supremely beautiful, in the aesthetic sense.

Room illuminated by a Clear High Pressure Mercury Vapor lamp. SPD: [1.4.1].

Room illuminated by four bi-component warm triphosphor fluorescents lamps. SPD: [1.3.3].

Room illuminated by a xenon flash. SPD: [1.12.1].

Room illuminated by four cool triphosphor Philips ActiViva Natural lamps. SPD: [1.3.8].

Room illuminated by a zinc lamp. SPD: [1.8.4].

The following renders were made based on the author's SPD and additional data for the zinc lamp the author provided the developers with.
Zinc lamps diagram render, based on structural data the author provided the developers with.

Zinc lamps diagram render, with one lamp lit and the other lamps resonating. SPD: [1.8.4].

From left to right: zinc, rubidium and mercury lamps. SPD: [1.8.4], [1.8.2] and [1.4.1].

From left to right: metal halide (Hg/Na/In/Tl), argon and xenon flash lamps. SPD: [1.6.1], [1.9.5] and [1.12.1].

From left to right: daylight halophosphate fluorescent, warm-white halophosphate fluorescent and bi-component triphosphor fluorescent lamps. SPD: [1.3.1], [1.3.2] and [1.3.3].

Random selection from the categories HPM, MH and various other categories, with Wattage taken into account.

Diode section. Blue LED, Red Diode Laser and Green Laser. SPD: [1.7.1], [1.7.2] and [1.7.3].

It's a fairly good exercise in color science to try to match each lamp separately with the corresponding spectrum on the previous page.
