Falling Sand Simulation Concept in Python

mostly a concept in python for falling sand simulation i guess the goal is to make a python version of the powder toy which is a falling sand sim the code is not finished yet, but i will update it as i go.

Main Features

• Particle Physics

  • Gravity and wind effects (maybe on the wind zones)
  • Temperature dynamics
  • State transitions (melting, freezing, evaporation)

• Particle Interactions

  • Collision detection
  • Chemical reactions (e.g., water + sand = wet sand, Lava + lower temperature = molten rock = rock)
  • Heat transfer between particles (e.g., Things seem to cool off as for heating up that's a different thing)

• Special Effects

  • Fire propagation sorta
  • Smoke generation
  • Liquid spreading (Could be improved )

• Optimization Features

  • Spatial partitioning grid (to reduce calculations)
  • Dormant particle tracking (to reduce unnecessary calculations)
  • Batch processing (to reduce unnecessary calculations)
  • Static User Interface (to reduce unnecessary calculations)
