Reverse engineering (RE) is the process of discovering the technological principles of a mechanical application through analysis of its structure, function and operation. It often involves taking something (e.g., a mechanical device, an electronic component, a software program) apart and analyzing its workings in detail, usually with the intention to construct a new device or program that does the same thing without actually copying anything from the original.

As computer-aided design has become more popular, reverse engineering has become a viable method to create a 3D virtual model of an existing physical part for use in 3D CAD, CAM, CAE and other software. The reverse engineering process involves measuring an object and then reconstructing it as a 3D model. The physical object can be measured using 3D scanning technologies like CMMs, laser scanners, white light digitizers or computed tomography. The measured data, usually represented as a point cloud, can then be modeled into a format appropriate for various uses. The point clouds themselves are not compatible with most 3D software, so applications like Imageware, Rapidform or Geomagic are used to process them into formats usable in other applications.

GSI was founded by industry veterans in the field of 3D computer graphics.

GSI Studio product suites provide solutions for entertainment, engineering, and other fields where 3D digital models are needed. GSI Studio is easy to use for new users and highly efficient for experienced professional designers and engineers to produce high quality results.

We also offer GSI Orchestra, a development toolkit (SDK), for customers and partners to build their application specific solutions. GSI Orchestra SDK package is completely modular with well-defined plug-in APIs so developers can effectively reuse their code and algorithms to create a new solution fast.

GSI offers professional services to help customers and partners to build domain specific solutions quickly and economically.

GSI provides the next generation design tools for 3D digital model creation. GSI Studio provides a comprehensive set of tools for professional designers to effectively transform 3D scan data into high quality ready to use models represented as refined meshes, curve networks, NURBS surfaces, and restructured meshes with full color and texture map support. GSI solution offers ease of use, high precision user control, and fast result generation.
