This example renders a 3D cityscape from geospatial building footprints, showing extruded building volumes colored in a uniform teal tone. It queries buildings within a given distance of a latitude/longitude point using Django’s GeoQuerySet (`outline__dwithin`) and converts each polygon outline with Shapely, then extrudes it with Trimesh’s `creation.extrude_polygon`. The scene is centered via a translation matrix, scaled, and exported as a GLB file using Trimesh’s `exchange.gltf.export_glb`. The visualization highlights building heights relative to their footprint areas.

This visualization generates downloadable 3D building models from a geospatial database. It queries building footprints within a specified radius of a given latitude and longitude, extrudes each polygon to a height proportional to the building’s height, and centers the resulting scene on the buildings’ centroid. The code uses Django’s GeoDjango for spatial queries, Shapely for polygon manipulation, and trimesh for scene creation and GLB export. The final output is a binary glTF file containing the extruded building geometry.

Display buildings in 3D

This example displays buildings in 3D on a Mapbox GL map centered on downtown Los Angeles, with a tilted and rotated perspective. It uses the Mapbox GL JS API to render a `fill-extrusion` layer from the `building` source-layer in the `composite` vector source, which contains OpenStreetMap building-height data. The extrusion height and base are interpolated from zoom level 15 to 15.05, creating a smooth transition as the user zooms in, with a gray color and 0.6 opacity.

This example renders a 3D mesh of a Brazier-shaped polyhedron, built from a JSON specification and processed through a sequence of geometric operations. The shape starts as a uniform hex grid prism, then applies operations such as `FaceScale`, `Extrude`, and `Kis` to selected upward-facing faces, producing a sculpted, bowl-like form with a faceted interior. The model uses a hex grid type with prism parameters and a "Dirty Metal" appearance preset, suggesting a material-based shading pipeline. The visualization relies on the JSON’s operation list to transform the base geometry, with disabled operations like `Lace` indicating optional refinement steps that remain inactive in the final output.

This visualization maps geographic data onto a three-dimensional globe using D3.js and Three.js. It renders landmasses as extruded polygons via `d3.geoPath` and converts them to Three.js geometry, while a `d3.forceSimulation` drives the rotation of the globe. The example also applies a canvas-based texture through `getImageData` to overlay graticule lines and subtle shading, and it animates the camera with `transition.attrTween` to smoothly orbit the planet. The data comes from a GeoJSON source embedded in the gist file.

Test of mapbox gl js builidng extrusion with Bend lidar test data

This example tests Mapbox GL JS building extrusion using Lidar-derived building footprint data from Bend, Oregon. Building polygons are styled with extrusion based on height properties, producing a 3D visualization of the urban landscape. The data, stored in a GeoJSON FeatureCollection, includes attributes such as elevation, height, and build height for each structure. The map renders the buildings as extruded 3D volumes, demonstrating Mapbox GL JS's ability to visualize lidar building data with realistic vertical dimensions.

This example visualizes a single geographic polygon representing an outline near Denver, Colorado, derived from a GeoJSON FeatureCollection. It shows the shape’s boundary as a closed loop, with coordinates defining a series of vertices that trace an irregular, elongated region. The rendering relies on a mapping library that processes GeoJSON data, likely using `d3.geoPath` to project the polygon onto a canvas or SVG, while the precise coordinate pairs (longitude and latitude) suggest the use of a geographic projection. The source gist provides the raw GeoJSON, and the visualization emphasizes the polygon’s spatial extent without additional layers or interaction.

This visualization combines a GeoJSON geometry collection with a thematic map overlay, using a base point at coordinates (152.5169, -29.8064) and multiple detailed polygon outlines. The polygons appear to trace irregular regions or clusters, likely representing geographic areas or boundaries, while the point marks a specific location. The rendering emphasizes spatial relationships and distributions through geometric shapes, suggesting a geospatial analysis or mapping of regional data.

This visualization uses a GeoJSON MultiPolygon dataset (from a gist by adkatrit) to draw a series of overlapping quadrilateral regions across a world map. The polygons are defined by latitude-longitude coordinates and are rendered as flat, outlined shapes that collectively tile a large portion of the globe. The map emphasizes geometric boundaries rather than natural coastlines, with each polygon edge drawn as a straight line between corner points, creating an abstract, grid-like partition of the world. The visualization is minimal, with no additional styling or data encoding beyond the raw geographic shapes.
