Cyberware Breakthrough Technology To Be Demonstrated at SIGGRAPH '94

Cyberware Introduces CyZip
CyZip, Cyberware's new technological edge, transports users from scanning limbo into scanning nirvana.

The new software is both literally and figuratively, a new direction in scanning. Traditionally, any object too big to be scanned in one pass must be digitized in sections. A complex object requires multiple scans, especially if it has occlusions or hidden surfaces. By scanning an object both cylindrically and linearly, more detail is captured.

The problem: Once all of the information is collected, one surface model must be built from the information in several scans.

The solution: CyZip. Software that combines all the information into one contiguous data set.

With CyZip, the cylindrical scan is used as a "registration", onto which the other scans are anchored. CyZip then matches the various points, and adjusts the position of each scan. Finally, the "registration" scan is removed, and the rest of the scans are "zippered" together into a continuous mesh that can be more easily manipulated.

Marc Levoy and Greg Turk of Stanford University, with the help of Cyberware, have been developing this tool over the last year. CyZip is a key element in the design of Cyberware's newest product, the Whole Body Scanner.

CYSURF: B-Spline Surfaces From Cyberware Scans
Reducing polygons can cause detail to wipe out. Cyberware's new scanning software, CySurf, allows you to shred the scan into a clean NURBS wave.

CySurf fits accurate B-Splines to the range map. It reads in Cyberware range and color scans, and writes out IGES 128 entities and SGI texture format file images.

The user interface fits surfaces to Cyberware scans quickly, by simply selecting the region of the scan for which surfaces are desired, and CySurf calculates the optimum control point arrangement. CySurf then fits the best looking B-Spline surface. More detail can be created using force points. With force lines, the surface can be bent to follow features of the scanned object.

CySurf allows creation of surfaces with a minimum number of control points, and it allows a good fit with a minimum of artifacts.

Every surface defines color and bump texture maps. When modeling or rendering, your B-Spline surfaces look as good as the original scans, but will have the advantages of compact storage. They also can be manipulated in a surface modeler.

MM Compact Motion Platform: Enhances 3D Scanning Of Small Objects
Cyberware's new motion platform is especially designed to support rapid color 3D scanning of small objects. The MM Platform provides both cylindrical and rectangular motion, which gives users complete freedom in scanning complex objects.

The MM Platform accommodates linear scans as wide as 350 mm and cylindrical scans of diameters as large as 460 mm. This makes the MM Platform ideal for scanning a wide variety of objects for many different types of applications. Possibilities range from packaging, such as bottles and cardboard cartons, to sculpted characters for computer animation.

As with Cyberware's other motion platforms, the MM performs 3D scans using any of the company's Model 3030 optical instruments. The scanner works by shining low-intensity laser light on an object to create a lighted profile, which is captured by high-quality video sensors from two viewpoints. An automated motion platform such as the MM permits users to digitize thousands of these profiles in a few seconds to capture the shape and color of the entire object. With the MM platform, a scan is done by moving the object while the optical instrument remains stationary.

Because the MM Platform's compact size, it is an excellent choice for facilities where space is at a premium. The MM also costs less than Cyberware's larger linear/cylindrical platform, the popular MS.
