ditions the OpenUSD asset once upstream, then streams 3D data
that reconstructs on the viewer's device. It doesn't send a decimat-
ed file, and it doesn't render frames in the cloud.
The expensive optimization step happens once upstream. Aer
that, delivery and on-device reconstruction scale independently.
No cloud GPU per viewer. The viewer's own device does the re-
construction, so delivery scales with bandwidth, the way video does,
not with a fleet of rented GPUs. OpenUSD (and glTF, obj, and stl)
goes in. The stream plays in three.js on the web, Unity, and WebXR.

We analyze the asset spatially and characterize its material and
lighting response. A radiance capture process places digital sensors
around and within the asset and records how the asset actually looks,
rather than just how it's built. We then build several levels of detail, so
the client can pull exactly the data needed given a view, device specs,
and network capabilities. The viewer experiences details that refine
as they move closer, much like a video player increasing its bitrate.

At SIGGRAPH 2026, we showed the Airship from the Academy So-
ware Foundation's Digital Production Example Library. In its original
form it's 44.3 GB, large enough that some of our own workstations
struggle to open it. With Miris spatial streaming, it reaches first view
in under a second on an iPhone 17 Pro, and it streamed to an iPad
over conference Wi-Fi during a presentation on stage.
The Airship isn't a one-off. More than 30,000 assets have gone
through the pipeline, exported from Blender, ZBrush, Substance
Painter, Cinema 4D, and more. The pattern doesn't change: author
in your DCC, export OpenUSD, publish, stream.
AWS Airship: 44.3GB asset, <1s time to first view, iPhone 17 Pro.

Live review: Evercast integrates with Zoom to support high-fidelity
review of 2D and 3D work. With Miris integrated into their platform,
each participant gets their own stream of the 3D asset, allowing
them to orbit, inspect, and discuss the work independently rather
than watching someone else's screen share. This also creates the
foundation for annotating and capturing notes directly on the 3D as-
set, rather than on a static image or proxy.
Asset management: Playbook, a DAM used across media, en-
tainment, and marketing teams, automatically sends uploaded 3D
assets through the Miris pipeline and returns an explorable preview
within minutes. We're applying the same approach with the AWS Vi-
sual Asset Management System (VAMS) team, where it can support
large industrial and digital-twin catalogs.
Marketplaces: CGAxis has uploaded thousands of high-end 3D
assets, giving buyers the ability to inspect each asset directly in the
browser before purchasing. Instead of relying on static images or
simplified previews, buyers can explore the asset with its intended
geometry, materials, and lighting.
The same stream reaches desktop browsers, iPhone and Android,
Apple Vision Pro, and XREAL glasses, through WebGL, WebGPU,
WebXR, or native apps built on the Miris SDK.

If your team is exporting optimized glTFs or USDZs for client review,
or signing off on turntable renders because the real asset won't open
on a laptop, take one of those OpenUSD files and upload it to the
free Miris beta. Then open the stream on your phone and compare it
to what you're shipping now.
