Infinity Generation vs Worldsmith

Infinity Generation's Infinity Engine supports runtime procedural generation of worlds, terrain, vegetation, planets, and other content for games and applications. Infinity Creator is a visual development application with a node graph and 3D scene viewer. Its noise tools are based on FastNoise2 and include Perlin, Simplex, Cellular, and other types. Generated scenes, models, and textures can be exported for use as assets.

The engine is described as compatible with Unity, Unreal, Godot, or custom game engines. Its C++ SDK and API support integration into existing projects, and developers can build custom procedural components for node graphs. Those components can call AI models to enhance dynamic content generation. The Free Alpha plan costs nothing and provides full software use during the Alpha period. Products using Infinity that make over $100,000 in annual gross revenue are subject to a 1% royalty. Creator lists Windows 10 and 11 (64-bit) and requires a Vulkan 1.1-capable graphics card; macOS and Linux are described as coming soon. Free Alpha support is best-effort through community and email. Enterprise includes priority direct support, with price not listed.

Worldsmith is a free, open-source browser application for generating fantasy world maps from a numeric seed, with a mode for rendering real Earth. Procedural terrain uses domain-warped fractal noise, including ridged mountain ranges, while biomes derive from elevation, moisture, and temperature. Rivers use D8 flow accumulation to form tributary drainage networks. Exports include PNG maps up to 5120 pixels, editable SVG maps up to 3840 pixels, JSON world data, and 8-bit or 16-bit heightmaps. The maker says heightmaps can be imported into Unity, Unreal Engine, Blender, and World Machine. Earth mode uses NOAA ETOPO1 elevation and bathymetry, averaged to about five kilometers per sample; synthesized detail is disclosed and can be disabled with Detail set to 0. The app runs entirely client-side without an account, server, or dependencies, and is offered under the MIT license.
