UDS Point Cloud

A UDS Point Cloud is the primary scene item for displaying Euclideon UDS format point cloud data in the scene.

Creating a Point Cloud

There are two ways to load a UDS point cloud:

Drag and Drop — Drag a .uds file from your file explorer and drop it into the scene viewport.
Add Scene Item — Click the Add Scene Item button (or press Ctrl+U) and enter the URL or file path to a UDS file.

Ribbon Settings

The point cloud ribbon tab provides access to visualisation and attribute controls.

Basic

Projection — Displays the current projection (SRID/WKT) for the model. Double-click the model in the Scene Explorer (or right-click and choose Use Projection) to apply the model's projection to the scene.

Attributes

When the UDS file contains additional attributes (intensity, GPS time, scan angle, displacement, etc.), colour-by-attribute controls appear here. These mirror the visualisation settings in Settings.

Scene Explorer Settings

Expanding a point cloud in the Scene Explorer shows:

Path — The URL or file path the model was loaded from.
Metadata tree — A read-only tree view of the internal UDS metadata, showing attributes, their sizes, and LOD blending configuration.

Right-Click Context Menu

Scene Node Metadata

The following keys can be set in the scene node metadata to override how the point cloud is loaded and projected.

Key	Type	Description
`ProjectionID`	string	SRID/EPSG code string to override the model's embedded projection.
`ProjectionWKT`	string	Well-Known Text (WKT) projection definition to override the model's embedded projection.
