# Progress Bar

The Progress Bar provides real-time updates on point cloud and annotation loading statuses, ensuring users are informed about the system's activities. It visually indicates the completion percentage for both point cloud rendering and annotation loading, offering clarity and transparency during the process.

With the help of visual cues, users can track the loading status of point clouds and annotations for each frame:

* **Little Black Box**: Indicates that annotations for the selected frame are fully loaded.
* **Little Grey Box**: Signals that point cloud loading has started for the frame.
* **Big Grey Box**: Confirms the point cloud has been completely loaded for the frame.

## Benefits

* **Enhanced Visibility**: Users can monitor the exact status of point cloud and annotation loading.
* **Improved User Experience**: Reduces waiting time by informing users when the frame (point cloud and annotations) is available to be rendered.

## Steps to Use the Progress Bar

{% stepper %}
{% step %}

#### Initiate Loading

Open the frame or sequence you want to annotate. The progress bar will automatically appear and start updating.
{% endstep %}

{% step %}

#### Monitor Progress

* **Little Black Box**: Appears when annotations for a frame are fully loaded.
* **Little Grey Box**: Indicates that point cloud loading has started.
* **Big Grey Box**: Confirms the point cloud loading is complete for the frame.
  {% endstep %}

{% step %}

#### Interpret Status

* **Little Black Box**: Annotations are loaded — wait for the point clouds.
* **Little Grey Box**: Wait for the point cloud to finish loading before proceeding.
* **Big Grey Box**: The frame is fully loaded, and you can now navigate to continue working seamlessly.
  {% endstep %}
  {% endstepper %}

{% hint style="info" icon="lightbulb-on" %}
Keep an eye on the boxes during your workflow to ensure frames are fully prepared before annotating, avoiding delays or incomplete data visibility.
{% endhint %}

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.imerit.net/3d-multi-sensor-fusion/labeling/3d-multi-sensor-fusion-labeling-editor/key-features/progress-bar.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
