# Polygon

A polygon is a plane figure formed by connecting a finite number of straight line segments end-to-end, where the first and last points meet to enclose a region.

### Slot Mode: Scale To Fit

Scales each row or column so that it takes up the full available space along that scanline.

| Parameter          | Type                   | Descripton                                                 |
| ------------------ | ---------------------- | ---------------------------------------------------------- |
| Scanline Direction | Horizontal or Vertical | The direction the rows are generated within the polygon.   |
| Set Row Count      | On/Off                 | Allows the adjusting of row count within the polygon.      |
| Row Count          | Decimal                | The number of rows within the polygon.                     |
| Start T            | Decimal                | How much of the polygon is filled starting from the top.   |
| End T              | Decimal                | How much of the polygon is filled starting from the bottom |

### Slot Mode: Bounded Grid

A grid of evenly spaced lines or points that is restricted to a specific, finite area or region.<br>

| Parameter    | Type    | Descripton                                             |
| ------------ | ------- | ------------------------------------------------------ |
| Slot Density | Decimal | The amount of space between drones within the polygon. |

### Slot Mode: Poisson

A distribution method that provides pseudo-random placement at a specified density.

| Parameter      | Type    | Description                                            |
| -------------- | ------- | ------------------------------------------------------ |
| Slot Density   | Decimal | The amount of space between drones within the polygon. |
| Random Seeding | Decimal | Points are randomly generated to ensure variability.   |

## Editing Polygons

When selecting a polygon, a toolbar will appear on the top of the scene view. This toolbar provides quick ways of manipulating polygons, editing geometry, and managing the anchor point. Buttons become enabled/disabled based on the current selection and state of the polygon.

{% tab title="Edit" %}
This button array provides a way to enter/exit polygon edit mode. Edit mode must be entered to modify polygon hull anchor points

<summary><img src="/files/APEALCzWBbystXSWWuUD" alt=""> <img src="/files/sAXW0ENcRli0qx5kYnOs" alt=""> Edit Mode (Exit Edit Mode)</summary>

Enter edit mode and allow geometry to be selected and manipulated. The button will toggle to an X when active and must be clicked again to exit edit mode.
