Graphite and Geogram are designed with the following principles in mind (some of them borrowed from the "Futurist Programmer" manifesto and programming notes, see http://www.graficaobscura.com/future/index.html and http://www.graficaobscura.com/future/futnotes.html):

• Make it as simple as possible (but not simpler)
• Make it as easy to use as possible
• Make it as easy to compile as possible
• Maximize speed
• Minimize memory consumption
• Minimize number of lines of code
• Minimize number of C++ classes
• Systematically document all classes, all functions and all parameters
• Systematically document the implementation of all algorithms, with relevant bibliographic references when applicable
• Assertion checks everywhere
• Zero warnings with all compilers / platforms / maximum level of warnings activated
• Perform systematic non-regression testing and memory checking, using a continuous integration platform (Jenkins)

The algorithms implemented in Geogram are specialized and tuned for most common uses. Users interested in generic / extensible / configurable implementations of these algorithms may use CGAL instead.
