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
  • Temperature dynamics
  • State transitions (melting, freezing, evaporation)

• Particle Interactions

  • Collision detection
  • Chemical reactions (e.g., water + sand = mud)
  • Heat transfer between particles

• Special Effects

  • Fire propagation sorta
  • Smoke generation
  • Liquid spreading

• Optimization Features

  • Spatial partitioning grid
  • Dormant particle tracking
  • Batch processing
  • Static User Interface
