Samples with High Resolution Spin Movies (1324)

These are samples that have high-resolution (one degree step) spin movies, in which the sample is shown rotating on a turntable, completing one revolution every 12 seconds (360 frames at 30 frames per second). These movies were made with one of several custom-built high-precision turntables: Because some of them are very small, tight tollerances are required to avoid wobble and vibration. Here is a picture of the rotation studio as it appeared in late 2004. The images were taken one every 5 seconds using a Canon 20D digital SLR.
To make downloading practical the movies are shown at 400x600 resolution, but the original 8 megapixel images (about 750MB per sample) are available on special request.
To get to the movie, click the turntable icon on the right of each sample line: This will take you to a 72-step QuickTime VR version. Underneath that will be a link taking you to the 360-step movie loop.

Click any element tile below to get the full entry for that element, or click on the sample picture to go directly to the description of that sample.
