Clip Immersive Viewer to Profile Extent

The Clip Immersive Viewer to Profile Extent tool limits the Immersive Viewer display to only the portion of the point cloud currently visible within the active Profile View. When enabled, this creates a focused, cross‑section–style view in the Immersive Viewer that mirrors the spatial extent of the profile.

This function is especially useful when inspecting linear features, comparing multiple LAS layers, or reviewing dense data in a constrained corridor.

How the Clip to Profile Extent Works

When a profile is drawn, LP360 defines a 3D clipping volume based on:

• The horizontal location of the profile line
• The profile width
• The vertical extent visible in the Profile View

Activating Clip IV to Profile Extent applies this volume directly to the Immersive Viewer , hiding all points outside the profile’s bounds while preserving full 3D interaction.

Important: This is a visualization filter only. No points are deleted or modified.

Recommended Workflow

1. Draw a Profile
   • Use any of the profile drawing tools (Profile Line or Profile Box) to define an area of interest.
   • Adjust profile width and depth as needed in the Profile View.
2. Open the Immersive Viewer
   • Launch the Immersive Viewer from the Navigation Toolbar, Map tab, or View menu.
3. Activate Clip to Profile Extent
   • In the Immersive View Toolbar, select Clip IV to Profile Extent .
   • The Immersive Viewer immediately updates to show only points contained within the profile.
4. Inspect in 3D
   • Rotate, pan, and zoom within the Immersive Viewer to examine the profile volume in a true 3D context.
   • Optionally change display modes (Elevation, Classification, Intensity) or shader modes to enhance interpretation.
5. Disable the Clip (Optional)
   • Toggle Clip IV to Profile Extent off to return to the full dataset view.

Common Use Cases

• Profile‑Based QA/QC
  Validate ground classification, breaklines, or structures along a corridor while maintaining 3D awareness.
• Multi‑LAS Comparison
  Display and compare multiple LAS layers spatially aligned to the same profile extents in the Immersive Viewer. 
• Dense Urban or Utility Inspection
  Reduce visual clutter by isolating only the data relevant to the profile path while using shading or X‑Ray visualization for subsurface or interior features.

Tips and Best Practices

• Adjust the Profile View vertical range before clipping to ensure important features are included.
• Combine Clip to Profile Extent with Draw Clipping Plane for additional spatial isolation when working in complex scenes.
• Shader modes (Sprite or X‑Ray) can be used simultaneously with profile clipping for enhanced visual clarity.

Notes and Limitations

• Requires an active Profile View; the tool has no effect if no profile is defined.
• The clipping region updates dynamically if the profile geometry or extent changes.
• The clip applies only to the Immersive Viewer and does not affect the Map, 3D, or Profile windows.
