The Client has developed a stereolithography restorative device that utilizes software for creating three-dimensional models of teeth. The software employs the binary STL file format, and its drawback is the large size of files containing information about an object. To solve this problem, Intetics has created an STL compression algorithm which works as a dynamic link library to be used with external applications. Two compression modes are available: lossy mode allowing for the posterization of triangle coordinates, and lossless mode providing precise data storage and decompression.
