From the coding week 2012:

Currently, the particles are stored as an array of structs (i.e. an array of the particle data structure). If the particles would be stored as a struct of arrays instead, this possibly has a number of advantages:

  • new properties can be added dynamically (no more compile time switches for new properties!)
  • the code may be more efficient

The goal of this task is not to rewrite all code like this, as this will probably not be doable in a week. However, it might be interesting to see whether it is possible and whether it slows down the code significantly.
