# Terrin
|
||||
|
||||
Geologically-based terrain generator.
|
||||
|
||||
v1.0 goals:
|
||||
- World generated on 2D plane.
|
||||
- Display two layers, asthenosphere and lithosphere.
|
||||
- Asthenosphere models convection currects and applies forces on lithosphere.
|
||||
- Lithosphere is initially split with random plate boundaries.
|
||||
- Model where constructive/destructive boundaries would be given asthenospheric
|
||||
forces.
|
||||
|
||||
Eventually, I would like to model continents and cratons, ocean basins,
|
||||
mountains, faults, different rock types, volcanism, ... everything.
