All these advantages are good reasons for an implementation of Python into RealFlow. Python is a full-featured scripting language with support for modern structures, such as object-oriented programming, also called OOP, or hashes for fast search algorithms. It is also possible to establish database connections to store and administrate large amounts of data. Other packages offer functions for numerical calculations, image generation, and OpenGL support. There are also many modules available for 3D graphics and visualization Next Limit introduced a Python interface giving the user the ability to overcome many of the restrictions known from earlier RealFlow versions. With RealFlow 2012 the entire Python distribution has been extended to support all the new features. An often-discussed issue is Python’s inability to use more than one processor, also called multi-threading. Please be aware that:
- Python is single-threaded by default, but RealFlow is not. Python’s limitation has a direct effect on RealFlow’s simulation speed when scripts are involved.
- Executing Python scripts is not completely single-threaded. Computers and operating systems always use more than one core or processor, though it is not possible to address them directly.
- Python provides some libraries for multi-threading support, but they only work on few platforms and in the worst case you have to recompile your Python distribution.
