Diamond Square

Implementation of the Diamond–Square Algorithm. This package can draw 2d terrains and 2d interactive terrains in pgzero and pygame.

Also can draw 3D terrains and 3D interactive terrains in panda3d.

Sample Generations

Sample Default 3D Terrain Sample Default Terrain Sample Desert Terrain Sample Tundra Terrain Sample Tropical Terrain Sample Volcanic Terrain Sample Swamp Terrain Sample Ocean Terrain Sample Mars Terrain

⚠️ You MUST include all four interactive functions for pgzero interactive

Missing even one will cause failures or unpredictable behavior.

Why Use diamond-square?

This package provides a complete implementation of the Diamond–Square algorithm with:

Fast rendering of the Diamond-Square algorithm written in C.
Multiple built‑in biomes.
Adjustable roughness, scale, and size.
Support for pgzero and pygame.
3d terrain drawing in panda3d.
Interactive mode in 2d and 3d terrains.
Change the border shape of the terrain (it is normally a square) using a filter function.
The ability to save generated terrain as an image.
Functions to add or remove biomes dynamically.

It is designed for both experimentation and game development, making 2d/3d terrain generation simple and customizable.

Go to /sample_code/custom_biome.py

Requirements for Pgzero Interactive

For Pgzero Interative Mode, it requires all four of the following functions to be placed in their corresponding pgzero event handlers:

...

def draw():
  terrain.draw_func(screen)
  ...

def on_mouse_down():
  terrain.on_mouse_down_func(pos)
  ...

def on_mouse_up():
  terrain.on_mouse_up_func()
  ...

def on_mouse_move():
  terrain.on_mouse_move_func(pos)
  ...

If any one of these is missing, the interactive mode will:

fail to update correctly
behave unpredictably
or stop working entirely

These must be placed in these functions in pgzero:

def draw(): → terrain.draw_func(screen)
on_mouse_down(pos): → terrain.on_mouse_down_func(pos)
on_mouse_up(): → terrain.on_mouse_up_func()
on_mouse_move(pos): → terrain.on_mouse_move_func(pos)
