Visibility Polygon

animated

Description

A 2D simulation in the framework Pygame for computing the visibility polygon regarding a robot that is considered to be a point $p$ on a plane with the presence of obstacles. The environment is a kind of corridor where the robot moves along. In order to make the robot explore the environment and generate the multiple visibility polygons that get generated through the exploration, the keyboard arrows can be used.

Usage

usage: visibility_polygon.py [-h] [-st  [...]] [-sr | --show_rays | --no-show_rays]

Implements the visibility polygon algorithm for a point.

options:
  -h, --help            show this help message and exit
  -st  [ ...], --start  [ ...]
                        Initial position of the robot in X and Y, respectively
  -sr, --show_rays, --no-show_rays
                        Show only the casted rays on screen

Examples

Display the robot only showing the cast of the rays and not the polygon

python3 visibility_polygon.py --show_rays

Set the initial position of the robot at $p = (20, 20)$

python3 visibility_polygon.py --start 20, 20
