# 3D View
The Bathymetric 3D View above is the primary workspace for viewing Omniscan 3D data, with support for point clouds, side-scan data, data manipulation, and more. Within SonarView, this window can be resized and rearranged to suit your preferred layout. To resize it, drag the top tab labeled “Bathymetric 3D View.”
## Stats
In the top left, you will see the Stats panel:
This displays the **position** and **depth** of your cursor, along with various statistics about the data collected so far.
## Tool Strip
In the bottom left, you will see the tool strip for this view:
In order from top to bottom you have:
**Depth Range Filter**
* Filters points by their vertical position in the water column. Use this feature to hide all points above or below a selected vertical threshold.
**Trim Points**
* Allows you to manually select a group of points and remove them from the view without permanently deleting them.
**Marks**
* Use this feature to mark specific features in the point cloud or side-scan data. Marks can be added in any of the following ways:
* Enable **Drop Mark** mode and left-click the feature
* Right-click the feature and hit 'Add Marker Here'
* Enter coordinates in the coordinate box within this expanded item
* Marks can be saved using the **GeoJSON** file export. Be sure to click **Stop** once you are finished placing marks.
* If you are connected to a live session and recording, marks will also be saved in that log and will appear during replay.
* Clicking a mark label in the view displays its coordinates and allows you to edit its size and label.
**Follow Mode**
* Toggles **Follow Mode**, causing the camera position to update along with your vehicle.
**Fit View**
* Toggles **Fit Mode**, automatically resizing the view to fit the displayed data.
**Waterfall Mode**
* Toggles **Waterfall Mode**, displaying data at constant time intervals rather than true spatial position. Marks are not available in this mode because they require georeferenced data.
## Display Controls
In the top right, you have the dispaly controls:
From top to bottom you have:
**Regular Bottom Points**
* Show regularly spaced bottom points. Can be useful for having clean visual data
**All Bottom Points**
* Show all collected bottom points
**Water Column Points**
* Show all points detected as being in the water column and not on the bottom.
**WC Point Density**
* If there is too much data in the water column (which could come from fish, boat wakes, etc.), you can decrease the point density to be able to see major features and filter out smaller features
**Map Overlay**
* Toggle map overlay visibility
**Show Fans**
* Toggle os3d fan beam(s) visibility. The fans give you a sense of the range of the os3d and are a good sanity check for mounting angles
**Side Scan Image**
* This renders the sidescan data as a mesh over the collected point data. A very useful configuration is having Water Column points on, Bottom points off, and Side Scan Image on which gives you something like this:
**Depth Color Mesh**
* This renders a mesh over the collected point data that's colored by depth
**Depth Contours**
* For either the Side Scan Image or the Depth color mesh, you can render depth contours to get a topological perspective of the bottom:
## Context menu
The context menu shows your cursor’s coordinates, lets you add a marker, and allows you to center both the **3D View** and **Side-Scan View** at the same time so the cameras are positioned over the same feature.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://docs.ceruleansonar.com/c/omniscan3d/sonarview/3d-view.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
