The purpose of Stony brook geometric data archive is to provide high quality geometric data to researchers in computer graphics and computer vision fields. The surfaces can be used for geometric modeling, geometric compression, surface parameterization, efficient rendering and many other applications.
The meshes are acquired using the technology holoimage developed by Stony Brook researchers. It is based on light interference and use wave optics method to recover the phase information from the photo. The hardware setup is illustrated as the following figure

The acquisition speed is as high as 24 frames per second. The depth resolution is around 50 microns. Details are explained in our technical reports.
The meshes represented as Microsoft DirectX mesh format, a list of vertices with color information and a list of faces with vertex ids. The meshes can be viewed using Microsoft DirectX mesh viewer.
