For developers

The whole model (including GUI) is written with C++, Python and JavaFX. JavaFX is responsible for GUI, and Python is used to develop all util tools (e.g., image format conversion), since it has numerious of third-party libraries available. C++ is for writting calculating radiative transfer Core for high performance, and this part is mainly based on an open source renderer Mitsuba. Mitsuba provides an flexible framwork to develop customer plugins and do parallel computing.
