Geomagic Shape lets users focus on form, not mathematics, to translate polygonal models created in Wrap or other programs into watertight NURBS surfaces that can be imported into other CAD/CAM systems.Īfter I made my polygon model, I moved to Shape to create the NURBS surface. These procedures are aimed at making the surface of a model suitable for other applications. The final 'polygon' phase consists of operations such as decreasing the number of triangles (here is where Decimator comes in), smoothing surfaces, creating straight edges and planes, and adding and moving points to provide finer control over surface deformation. My experience using the samples provided with the program ranged from 2 to 3 minutes for most simple scans to nearly 15 minutes for a sample containing more than 400,000 points. The length of processing time depends on the number of points in the model. This step occurs automatically and, after several minutes of processing, produces a fairly ac curate initial, editable model. Next, in the 'wrap' phase, the program computes the polygonal model. During the 'point' phase, you can modify the point set using editing methods such as cropping or erasing to remove unwanted or extraneous points. To run Geomagic Studio through its paces, I loaded a sample point cloud data file supplied with the program. The third module, Geomagic Decimate, is a polygon reduction tool for lowering the number of triangles in a model-thus improving rendering speed and reducing file size while preserving surface geometry. The resulting model can be saved and exported in various file formats, including DXF, IGES, GeomView OOGL, STL, VRML, Wavefront (OBJ), Inventor (IV), 3D Studio (3DS), and Geomagic's own WRP.

Geomagic Shape converts polygonal models into surface models consisting of NURBS patches. Raindrop Geomagic Studio's Wrap functions automate the construction of polygonal surfaces from scanned or digitized point cloud data. Wrap accepts IGES point clouds as well as data from MicroScribe digitizers and Cyberware, Digibotics, Hymarc, and other scanners. Geomagic Wrap is an automatic surface-generation tool that mathematically 'wraps' a polygonal surface around point-cloud data. Geomagic Studio consists of three programs-Wrap, Shape, and Decimate-within a unified interface that guides you through the various processes. Geomagic Studio 2.0 from Raindrop Geomagic simplifies this task by automating the creation of NURBS surfaces from point-cloud and polygonal information, enabling you to rapidly create 3D models for design and manufacturing. Creating free-form surfaces is challenging and time-consuming, particularly when you have to create them from point cloud data obtained from physical object scans.
