Documents and Tours

This release brings a big change in the document data structure and a major new feature: tours!

• New unified document format: The new format replaces the item.json and presentation.json files with a universal scene description format. The new Voyager document format is 99% compatible with glTF, and therefore easy to understand and read for everyone with prior exposure to the well-established glTF format. In the future we might add tools for converting between document.json and glTF.
• With the new document format, Voyager introduces new URL variables:
  • root specifies the root folder for all assets, including the base document, relative to the page URL
  • document specifies the path to the document.json to load, relative to the root
  • The remaining variables model, geometry, and texture work as before (all relative to the root)
• New tour editor: Voyager story comes with a new built-in task to create and edit guided tours. A tour is a sequence of snapshot steps, state captures of the Voyager viewer. When playing a tour, similar to a power-point presentation, the user moves forward (or backward) from step to step. All Voyager properties captured (such as camera position, lights, etc.) are seamlessly animated between steps.
• Lots of fixes and improvements
