What is Alterno Spatial Review?

Visual feedback for 3D websites

Alterno Spatial Review is a browser-based representation and feedback editor. Inspect a website’s 3D scenes, camera paths, and assets, show the changes you want, and share structured feedback with your coding agent.

The website must expose the Spatial Review discovery contract, normally through the public SDK. Pasting an arbitrary website URL does not make its geometry available automatically.

Choose a workspace

• Review scene composition and object placement
• Review camera paths, timing, and field of view
• Inspect asset parts, geometry, and materials
• Explore attributed example projects

Work with a coding agent

Connect a compatible browser agent through WebMCP, or download feedback JSON and give it to your coding agent. The external agent applies requested changes to the website’s source using its own authoring tools; editor changes alone do not deploy or rewrite the website.

• Agent connection and capability guide
• Install the public Spatial Review SDK

Storage and fidelity

Saved reviews use browser-local storage. This editor does not provide a cloud account or cross-device review synchronization. Export files when you need a portable copy.

The review is a supplied representation, not a pixel-exact copy of the live website. Available geometry, materials, textures, lighting, and capture fidelity depend on the integration and renderer. Missing source geometry may appear as bounds proxies.
