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)
