Technology, Accessibility, and Browser Compatibility

The Unity 3D platform used to host the 3D content for this volume is built on WebGL and is not compatible with some browsers and mobile devices. To access the 3D model, we recommend using a desktop or laptop computer and a modern web browser (Chrome 54+, Firefox 40+, Safari 9+, Edge 15, Opera 43+, more details). Unity’s documentation maintains a list of compatible browsers and graphics cards. To access database records linked in the 3D model, your browser must allow pop-ups (Chrome | Firefox | Safari | Opera).

If you do not wish to interact with the 3D model, or cannot use it, you may interact with the publication in Accessibility Mode. To enter Accessibility Mode, click the “Accessibility Mode” link in the top right corner of any page in the volume.

3D Model

The interactive content found in the 3D model serves as a visual reference for the narrative text. It contains 3D models of the site’s individual stratigraphic units, schematic reconstructions of key features, descriptive data, and direct links to entries from the project’s online database. Interaction with this content is essential to the way this publication communicates our interpretation of the Tincu House. Reconstructions and phase groupings, the toggles for which are accessed by undocking the menu at the left of the 3D interface, illustrate our understanding of the structure’s evolution. Links in the main text of the volume will guide you through a structured exploration of the house’s stratigraphy and the reconstructions developed by our team. Readers are encouraged both to follow the narrative laid out in the text and to explore the 3D content freely. Investigation into the data behind the interpretations and reconstructions is supported by access to the project’s database.

Within the 3D model viewer, you may move your mouse cursor over any icon to reveal its function. There are two viewing modes, “orbit view” and “explore on foot.” In “orbit view,” you may zoom in and out using the zoom bar on the right-hand side of the viewer. Clicking and dragging the left mouse button and dragging will move the camera. In “explore on foot” mode, the arrow keys or WASD keys control movement, and holding down the middle mouse button allows you to zoom in for a closer view of features.

Within the 3D model viewer, trowel icons are associated with each stratigraphic unit. Hovering over the trowel icon will cause the outline of that stratigraphic unit to glow red, providing a visual association between the trowel icon and the stratigraphic unit for which it contains information. Clicking on any trowel icon will pull up basic information on the stratigraphic unit associated with the icon. The basic information presentation here uses the system of symbols described in the introduction to this volume. The “go to ark” button provides a link to the database entry for the relevant stratigraphic unit. The trowel icons for any given stratigraphic unit appear as you move closer to it, and disappear again as you move away. If no trowel icon appears for a stratigraphic unit, and you wish to access information about it, move closer until the trowel icon appears.

The 3D content for this volume is designed for a laptop or desktop device. Using smaller mobile devices may result in unexpected behavior and changes in layout.
