AmiTerrain

A modern terrain generation and landscape rendering system for classic Amiga computers.

AmiTerrain is inspired by Vista/VistaPro, Scenery Animator and World Construction Set, but is designed as a new native Amiga toolchain rather than a clone.

Goals

• Native Amiga terrain generation and rendering
• Deterministic procedural terrain generation
• Import real-world elevation data
• Tile-based processing for worlds larger than available RAM
• Open file formats and documented interchange
• CLI, library API and later ARexx/GUI interfaces
• Useful both on real Amiga hardware and high-speed emulators/VMs
• Integration with AmiScene-SDK and the wider Ploos Amiga toolchain

Initial architecture

• libamiterrain — reusable terrain engine
• amiterrain-cli — headless command-line frontend
• amiterrain-worker — future distributed renderer/worker
• GUI — later milestone
• ARexx port — later milestone

M0

M0 establishes the deterministic terrain core and interchange baseline.

Planned M0 scope:

• deterministic seeded terrain generation
• RAW heightmap import/export
• PGM heightmap import/export
• IFF-based native terrain container draft
• terrain statistics and validation
• CLI suitable for CI
• host-side tests
• Amiga cross-build skeleton

Rendering, erosion, GIS import and GUI are intentionally deferred until the core data model is stable.

Terrain formats roadmap

M0

• RAW 8/16-bit heightmaps
• PGM
• native IFF terrain container

Implemented interchange

• IFF/ILBM heightmaps (1–8 plane import; 8-plane grayscale export)
• ASCII Grid / ASC
• XYZ regular grids
• HGT / SRTM
• USGS DEM
• DTED

Later

• PNG 16-bit grayscale
• GeoTIFF
• OBJ / PLY / STL
• LightWave / Imagine / POV-Ray interchange
