Terms
Holograms (a.k.a "the what") are projections of 3D content in the real world. These could be:
1.
Model hologram: static or animated. File formats include .obj, .stl, .fbx, .glTf, .glb, .usdz, .dae, and more.
2.
Video hologram: regular or 360 degrees. File formats include .mp4, .mov, and more.
3.
Image hologram: static or animated. File formats include .png, .jpg, .gif, .svg, and more.
Targets (a.k.a "the where") are the real world places on which the 3D content appears. These could be:
1.
Surface target: any surface. e.g., a floor, table, ground, wall, and more.
2.
Location target: geographic location represented by name or latitude and longitude coordinates (e.g., New York, London, 40.713054 & -74.007228).
3.
Image Target: static images. Formats include .png, .jpg, and more.
A pair of a hologram and a target is referred to as a Content Entry, which has its own unique ID and is represented by a single Content Card in the Content page.
Content Cards
The Content page displays all models, images, and videos in the project as individual content cards.
Each card allows you to:
1.
Preview the hologram
2.
See the original file name
3.
Review the target
4.
Download different version of the file by clicking on the buttons with the different format names
5.
Delete the asset by clicking the
icon
6.
Copy a short shareable link to the 3D asset by clicking the
icon
7.
Get QR codes by clicking the
icon to immediately see the hologram with your phone as described in "See it in AR". Here the QR codes acts as an way to direct viewers to 3D asset or serve as an image target.
You can share 3D models instantly by clicking the
icon which will copy a short direct link to the model in the from of https://go.echo3D.co/ABCDinto your clipboard. Sharing this link will also automatically show others a QR code they can scan for easy access.
If you access the console through your phone, you will be able to immediately preview 3D models by clicking the
arrow at the top right corner of any card will pull up metadata for that content entry. Here, you can add, delete, edit, upload, or download metadata for your content entry.
For example, adding a metadata with key scale and value 2.
Built-in keywords will be suggested through a drop-down list but you can add any key and any value. More built-in keywords such as scale can be found here and here.
The content entry ID associated with the hologram is displayed at the bottom of the card.
