Learn more about 3D holograms, spatial targets, content entries, and content cards.
Holograms (a.k.a "the what") are projections of 3D content in the real world. These could be:
Model hologram: static or animated. File formats include .obj, .stl, .fbx, .glTf, .glb, .usdz, .dae, and more.
Video hologram: regular or 360 degrees. File formats include .mp4, .mov, and more.
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:
Surface target: any surface. e.g., a floor, table, ground, wall, and more.
Location target: geographic location represented by name or latitude and longitude coordinates (e.g., New York, London, 40.713054 & -74.007228).
Image Target: static images or image trackers. Formats include .png, .jpg, and more or.iset, .fset, and .fset3.
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.
The Content page displays all models, images, and videos in the project as individual content cards.
Each card allows you to:
Preview the hologram
See the original file name
Review the target
Download different version of the file by clicking on the buttons with the different format names
Delete the asset by clicking the
Copy a short shareable link to the 3D asset by clicking the
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.
