forge3d 1.28.0

forge3d: Rust/WebGPU offline 3D maps with local GIS raster read/write, CRS, affine, windowing, and reprojection support

Python-first terrain and scene rendering on top of Rust + WebGPU.
Interactive viewer, offscreen rendering, overlays, point clouds, notebooks, and production outputs.

Install

pip install forge3d

Optional extras:

pip install "forge3d[jupyter]"   # notebook widget support
pip install "forge3d[datasets]"  # on-demand sample datasets
pip install "forge3d[all]"       # everything

Quick Start

import forge3d as f3d

dem_path = f3d.fetch_dem("rainier")

with f3d.open_viewer_async(terrain_path=dem_path, width=1440, height=900) as viewer:
    viewer.set_z_scale(0.1)
    viewer.set_orbit_camera(phi_deg=28, theta_deg=49, radius=5400, fov_deg=42)
    viewer.set_sun(azimuth_deg=302, elevation_deg=24)
    viewer.snapshot("rainier.png", width=1920, height=1080)

What forge3d Covers

Open-source workflow:

• Interactive terrain viewing through open_viewer_async() and ViewerHandle
• Terrain snapshots from GeoTIFF or numpy DEM inputs
• Raster overlays, vector overlays, labels, and camera automation
• LAZ/COPC/EPT point-cloud loading
• COG access, CRS helpers, datasets, presets, and notebook widgets
• Native/offscreen rendering with Scene, Session, TerrainRenderer, and TerrainRenderParams
• Geometry, mesh, vector, SDF, path-tracing, lighting, and terrain scatter helpers

Pro workflow:

• MapPlate, Legend, ScaleBar, and NorthArrow for cartographic composition
• SVG/PDF vector export
• Building import pipelines for GeoJSON, CityJSON, and 3D Tiles workflows
• Mapbox-style import and scene bundles

Documentation Map

• Quickstart: install, first viewer session, first overlay, first notebook widget

Examples

The repo ships a broad set of runnable examples in examples/, including:

• interactive terrain scenes and raster overlays
• Mapbox-style, labels, and picking demos
• point-cloud and building viewers
• camera animation and terrain camera rigs
• COG streaming and offscreen terrain rendering
• pure-Python composition examples and notebooks

Run any script with python examples/<name>.py --help when it exposes CLI options.
