3dstreet-assets-dist

Distribution repo for 3DStreet assets for use by first and third-party clients.

The entirety of this repo is available on this subdomain of 3dstreet.app: https://assets.3dstreet.app/

This repo includes a few different utils for processing glb/gltf files to prepare them for use in 3DStreet.

Web-based gltf/glb thumbnail generation utility

This is the easiest way to create thumbnails for glb files using a browser interface:

1. Ensure that the prerequisite packages are installed via npm i
2. Start the utility by running npm start.
3. Generate the desired screenshots of the models/parts. (Instructions are included in the web app.)
4. Download the screenshots.

CLI gtlf/glb processing tools

These command line interface glb processing utilities are separate from the web-based tool, choose whichever works best for your needs. These tools are handy if you want to create and automated pipeline.

• npm run gltf:audit - Audits GLB/GLTF models in ./src/models and generates (or overwrites) a catalog.json file with the results
• npm run gltf:build - Processes and optimizes GLB/GLTF models from ./src/models to ./dist/models (with Draco compression)
• npm run gltf:screenshots - Generates screenshots from processed models in ./dist/models and outputs to ./dist/img
• npm run gltf:pipeline - Runs the complete pipeline: audit, build, and screenshot generation in sequence
• npm run gltf:center -- <PATH> - Optimizes (flattens hierarchy, combines meshes) and centers the origin of GLB/GLTF models on horizontal axes (X/Z) with bottom at ground level (Y=0). Use -i <path> for input and optionally -o <path> for output. Output files are saved with -centered suffix
