Gold Teapot

Simulating metallic gold in computer graphics is a daunting task since gold is not just a color but rather a combination of a bronze color and a tinted reflection of the surroundings. This gold teapot is an attempt to recreate the gold objects seen in the classic Benson & Hedges commercials produced by Robert Abel Productions in the mid-eighties. The gold effect is achieved by applying a spherical environment map of a gold fireplace to the teapot and mixing it in with a gold base surface color. Also of particular interest is the high-quality anti-aliasing of the spherical environment texture using MIPmap filtering; without the filtering the reflected image of the fireplace would look aliased and distorted.
