6. Embedded 3D Viewers & External Media (2-Click Solution)

XGRIDS 3D Viewer: We showcase interactive 3D Gaussian Splatting captures using a two-click facade solution. When you view a project page, no connection to XGRIDS servers is established initially, and no personal data is transmitted.

Only when you actively click the "Load 3D Viewer" button, you give consent pursuant to Art. 6(1)(a) GDPR, and an iframe connecting to the external 3D viewer (XGRIDS, Shenzhen / AWS Cloud) is loaded, which transmits your IP address to their servers.

Panopto Video Embeds: Academic presentations and research videos are embedded via the Panopto platform of Hochschule Düsseldorf (HSD). Videos are also embedded behind a two-click facade and only establish a connection when you click the play button.
