Previewing 3D assets

Experience Manager supports the upload, delivery, and interactive preview of 3D assets as part of the authoring process.
The interactive 3D viewer is available from the asset details page in AEM. The viewer includes, among other things, a collection of interactive camera controls that let you orbit, zoom, and pan the 3D asset.

        model.bin
        textures (folder)

Performance considerations when you preview 3D assets

The time it takes to open a 3D asset in the asset details view page depends on several factors such things as bandwidth, image complexity, and latencies to the server.
In addition, the capabilities of the client computer—such as a workstation, notebook, or mobile touch device—are also important to consider when you manipulate the camera interactively. A reasonably powerful system with good graphics capabilities can make the interactive 3D viewing experience smoother and more favorable.
