Mapgen V2.2

Here’s a professional write-up for MapGen v2.2, suitable for release notes, a changelog, or a project summary.

Algorithms & Implementation Notes

• Noise: Simplex for fewer artifacts; Perlin acceptable.
• Erosion: Implement hydraulic erosion with thermal fallback; keep performance-vs-quality toggles.
• Rivers: Use steepest-descent or D8 flow; ensure sinks are resolved with depression filling.
• Performance: Tile-chunking, multi-thread noise, and mipmapped sampling for large maps.
• Determinism: Use single PRNG for all stochastic steps seeded from seed_hash.
• Modularity: Each pipeline step as replacable module with clear inputs/outputs.
• Scalability: Support streaming generation for procedurally revealed maps.

How to Generate Your First Map in v2.2

The user interface has been redesigned from the "sliders and number fields" approach to a more intuitive node-graph system. Here is a quick tutorial:

Step 1: Choose a Template Select from six presets: Archipelago, Continent, Pangea, Island Chain, Fjordland, or Fractal Maze. mapgen v2.2

Step 2: Configure the Noise Function MapGen v2.2 now supports Simplex, Perlin, and the new Cellular Voronoi noise types. For a natural continent, choose Simplex with 5 octaves.

Step 3: Set Climate Poles In the "Climate" tab, drag two markers on the map. The generator will interpolate temperature and humidity between them. Here’s a professional write-up for MapGen v2

Step 4: Run Erosion (The v2.2 Magic) Click "Simulate Water". Watch as blue streaks cut canyons and deposit green sediment zones in real-time. The default simulation runs for 500 iterations, but you can stop it early or let it run to 2,000 iterations for hyper-realistic detail.

Step 5: Style and Export Open the "Cartographer's Studio" (new in v2.2). Here you can choose rendering styles: Parchment, Vintage, Satellite, or Tactical Green. Export as PNG, SVG, or the proprietary .mapgen project file. Algorithms & Implementation Notes

1. Hybrid Thermal-Hydraulic Erosion (Real-Time)

Previous versions offered hydraulic erosion (water-based) as a post-process. MapGen v2.2 introduces hybrid erosion, combining thermal weathering (rockfall/ scree slopes) with hydraulic transport. The result? Mountain ranges that look geologically plausible, with alluvial fans, V-shaped valleys, and realistic sediment deposits. Best of all, the new erosion pipeline runs 40% faster on multi-core CPUs thanks to a revamped job scheduler.

Compatibility

• Works with Python 3.9+, Godot 4.x, and Unity 2022 LTS (via native bindings)
• Backward compatible with v2.0/v2.1 map schemas (automatic migration)
