# Contextualize point clouds in asset-centric and hybrid projects

> Generate point cloud volume suggestions during processing and contextualize by creating point cloud bounding volume annotations linked to assets.

## Contextualize

In **asset-centric (legacy)** and **hybrid** projects, point cloud contextualization suggestions are produced during point cloud processing (when enabled). To contextualize, create annotations that link suggested bounding volumes to assets.

<Note>
  For user interface-based contextualization of point clouds, see [Contextualize point clouds](/cdf/3d/guides/pointcloud_contextualize).
</Note>

<Steps>
  <Step title="Get point cloud volume suggestions">
    Point cloud volume suggestions are produced during point cloud processing when you enable volume generation in the processing configuration (for example, by enabling `processTilesOptions` in the point cloud pipeline configuration).

    <Note>
      If volume suggestions are not generated for your revision, there’s nothing to approve. Re-run processing with volume generation enabled.
    </Note>
  </Step>

  <Step title="Create contextualization annotations">
    To approve contextualization by linking bounding volumes to assets, create annotations with the [Annotations API](https://docs.cognite.com/20230101/annotations/create-annotations).

    Use the **`pointCloud.BoundingVolume`** annotation type and set the appropriate reference in the annotation `data`.
