Pros of terrain

• Simpler and more focused on generating realistic terrain
• Faster generation due to less complex features
• Easier to integrate into other projects as a terrain generation module

Cons of terrain

• Less feature-rich compared to Fantasy-Map-Generator
• Limited customization options for map elements
• Lacks additional features like city placement, roads, and political boundaries

Code Comparison

terrain:

function generateTerrain(width, height, roughness) {
  let map = new Array(width * height).fill(0);
  // ... terrain generation logic
  return map;
}

Fantasy-Map-Generator:

function generateTerrain() {
  const cells = grid.cells;
  cells.h = new Uint16Array(cells.i.length);
  HeightmapGenerator.generate();
  // ... additional map element generation
}

The terrain project focuses solely on terrain generation, with a simpler API and implementation. Fantasy-Map-Generator, on the other hand, incorporates terrain generation as part of a more comprehensive map creation process, including additional features and map elements.

While terrain provides a straightforward approach to generating realistic landscapes, Fantasy-Map-Generator offers a more complete solution for creating detailed fantasy maps with various elements such as biomes, cultures, and settlements.

Pros of worldengine

• More scientifically accurate world generation based on plate tectonics and erosion
• Generates 3D heightmaps and allows for 3D visualization
• Provides detailed biome and climate data

Cons of worldengine

• Less user-friendly interface, primarily command-line based
• Fewer customization options for map styling and aesthetics
• Less active development and community support

Code comparison

Fantasy-Map-Generator (JavaScript):

function generateTerrain() {
  const cells = pack.cells;
  cells.h = new Uint16Array(cells.i.length);
  const N = cells.h.length;
  const regionCells = [...new Set(cells.region)].map(r => cells.i.filter(i => cells.region[i] === r));
}

worldengine (Python):

def generate_world(seed, width, height):
    world = World(seed, width, height)
    world.set_ocean_level()
    world.generate_plates()
    world.generate_elevation()
    return world

The code snippets show different approaches to terrain generation. Fantasy-Map-Generator uses a cell-based system with regions, while worldengine focuses on plate tectonics and elevation generation.
