The 3D Tiles Overview is an approachable and concise guide to learning about the main concepts in 3D Tiles and designed to help integrate 3D Tiles into runtime engines for visualization and analysis of massive heterogeneous 3D geospatial content.

This guide augments the fully detailed 3D Tiles specification with coverage of key concepts to help developers jumpstart adopting 3D Tiles.

This directory contains the source files for generating the 3D Tiles reference card.

The input files are SVG files, originally created with Inkscape. They can be converted to PDF files either by opening them in Inkscape and saving them as PDF, or more conveniently, using the convertAllToPdf.bat batch file. The file uses the command-line functionality of Inkscape to convert each SVG file from the input directory into a PDF file, which is then written into the /output subdirectory.

The resulting PDF files can be combined with any PDF tool, for example PDFtk Server. The combinePdfs.bat batch file contains the call that combines all PDF files from the /output directory, and writes the result as into the base directory as 3d-tiles-overview.pdf.

The /resources subdirectory contains the images (screenshots and SVG versions of the logos) that are used in the overview. They are not necessary for creating the PDF files, but are added here for reference.

The file /resources/3d-tiles-overview-tables.odt is an OpenDocument Text that can be edited with any standard office program. It contains most of the tables that are used in the overview. In order to change one of the tables, it is edited in the ODT file, exported as PDF, and imported into Inkscape. (Considering the limited support for tables in Inkscape, this still seemed to be the most simple approach here.)

Thanks to Marco Hutter, a long-time member of the glTF community, for designing the first version of the 3D Tiles Overview.
