# Hotzone

Hotzone lets you isolate any section of a point cloud to work exclusively within that area, eliminating the risk of accidentally segmenting surrounding points. Only the selected portion is active, enabling significantly smoother playback and rendering performance. Merge isolated point clouds seamlessly once your work is complete and bring your full dataset back together.

## Use Cases

* **Precision Segmentation** - Focus on a specific structural element, like a pillar or façade, without disturbing adjacent point data.
* **Large Dataset Navigation** - Isolate dense or complex zones in massive scans to enable smooth playback and responsive interaction.

***

## Benefits

* **Accident-free editing** - Surrounding points are fully protected while you work inside the hotzone.
* **Smoother performance** - Rendering and playback are faster since only the active zone is processed. User can also merge larger frames and see faster rendering.
* **Focused workflows** - Reduces visual clutter and cognitive load when working on complex or large-scale scans.

## Steps to use Hotzone

{% stepper %}
{% step %}

### Enable Hotzone

Enable the 'Isolate' toggle from the header.
{% endstep %}

{% step %}

### Define the boundary

On toggling it ON, make multiple clicks on the point cloud to draw a boundary and right click to apply hotzone.
{% endstep %}

{% step %}

### Label within the isolated area

All the points falling outside the defined boundary will be hidden from view. Users can now start labelling objects in the visible patch without background disturbance.
{% endstep %}

{% step %}

### Continue working across frames

* Navigate to the next frame and observe isolation is applied across frames, preserving context.
* Optionally merge the point clouds to understand the scene after removing unnecessary points.
