The Making Of

This is a React web app using Babylon.js as the 3D rendering engine. Babylon has lots of good documentation and examples.

The terrain mesh (California desert) was created by getting geotiff data from the USGS Earth Explorer site. QGIS was used to crop the raw tiff and gdalwarp was used to convert the tif to a format that the Tin-Terrain utility likes (Web Mercator projection EPSG:3857 and 'square pixel' aspect ratio). Tin-Terrain converted the tiff to an optimized triangulated mesh in obj format, and Blender was used to add the satellite imagery and export as gltf. This conversion was a bit of a hassle because the input obj has some very odd scaling and position values. I re-exported the obj as STL to make sure the corrected vertex values were baked in before re-exporting as gltf.

Once loaded into the Babylon scene, the scaling needed to be fixed due to the BJS handed coordinate system. The normals had to be flipped also. All the other objects are BJS primitives from the provided polyhedra examples.

Available Scripts

In the project directory, you can run:

npm start

Runs the app in the development mode.
Open http://localhost:3000 to view it in the browser.

The page will reload if you make edits.
You will also see any lint errors in the console.

npm test

Launches the test runner in the interactive watch mode.
See the section about running tests for more information.

npm run build-web

Builds the app for production to the build folder.
It correctly bundles React in production mode and optimizes the build for the best performance.

The build is minified and the filenames include the hashes.
Your app is ready to be deployed!

See the section about deployment for more information.

npm run eject

Note: this is a one-way operation. Once you eject, you can’t go back!

If you aren’t satisfied with the build tool and configuration choices, you can eject at any time. This command will remove the single build dependency from your project.

Instead, it will copy all the configuration files and the transitive dependencies (Webpack, Babel, ESLint, etc) right into your project so you have full control over them. All of the commands except eject will still work, but they will point to the copied scripts so you can tweak them. At this point you’re on your own.

You don’t have to ever use eject. The curated feature set is suitable for small and middle deployments, and you shouldn’t feel obligated to use this feature. However we understand that this tool wouldn’t be useful if you couldn’t customize it when you are ready for it.
