The VCGlib is a C++, templated, no dependency, library for manipulation, processing and cleaning of triangle meshes
Role in this project:Backend Developer
Backend DeveloperContributions:510 commits, 2 pushes, 1 issue in 13 years 5 months
Contributions summary:Federico implemented the core C++ functionality of the library, by adding the base functionalities for handling triangle meshes, like base.h, which defines core mathematical concepts. The user's work focused on defining and including essential math functions like sqrt and abs for performance optimization, as well as defining and using standard math constants such as M_PI. Also the user added the definition of basic classes like math as well as the functionallity of Clamp(), ToDeg() and ToRad().
