Experiment with 5 terrain generation algorithms. Real-time preview updates as you adjust sliders.
Sliders: Frequency (detail scale), Octaves (detail layers), Persistence (layer intensity falloff), Amplitude (height range), Erosion (water-carved rivers).
Views: Top-Down (colored tiles), Isometric (3D-like with height shading), Heightmap (grayscale).
Algorithms: Perlin (smooth), Simplex (organic), Voronoi (cellular), Value Noise, Diamond-Square.
Export saves as a heightmap PNG. Objects places trees, rocks, and buildings on appropriate terrain.
