Short answers, pulled from the story.
Researchers at Saarland University began developing BALL as a commercial product in 1992. The software was initially designed to handle complex molecular modeling tasks for bioinformatics.
Developers decided to release the source code under the GNU Lesser General Public License by the early 2000s. This move transformed BALL from a paid commodity into free-of-charge open-source software.
The BALL library supports file formats like PDB, MOL2, MOL, HIN, XYZ, KCF, SD, and AC for import and export. Secondary data sources such as DCD, DSN6, GAMESS, JCAMP, SCWRL, and TRR are also readable within the system.
BALLView was presented as the first complete integration of real-time ray tracing into a molecular viewer at CeBIT 2009. The software uses Qt and OpenGL as render back-ends alongside the real-time ray tracer RTFact.
SIP automatically creates Python classes that mirror all relevant C++ classes exactly with identical names. This design allows developers to switch from C++ to Python seamlessly while keeping both languages synchronized during updates.
