The 3D contextualization APIs create and remove links between 3D domain objects and CogniteAsset instances in data modeling projects. These links are scoped to specific 3D model revisions and let you navigate between 3D content and related assets.
These endpoints are available only in data modeling projects.

​
What these endpoints do

The group covers three contextualization types:
  • CAD nodes to assets for a specific CAD model revision
  • 360 image annotations to assets for a specific 360 image revision (one CogniteAsset to many Cognite360ImageAnnotation)
  • Point cloud volume references to assets for a specific point cloud revision
Each type has a create endpoint and a delete endpoint for managing those links.

​
How this relates to 3D asset mapping

These APIs link 3D objects to CogniteAsset instances in data modeling spaces. 3D asset mapping maps 3D model nodes to Cognite Data Fusion (CDF) assets for bidirectional navigation between 3D views and asset data.
