vec2d 0.2.1

Maths and Graph functions for vectors on the 2D plane

Vector2D library

Helper library with Math and graphing related functions for vectors in the 2D plane.

Usage

Install the library by typing:

python -m pip install vec2d

Once installed, you'll have access to the Math and graphing packages:

from vec2d.math import add
from vec2d.graph import draw, Arrow, Colors, LineStyles

u = (2, 0)
v = (1, 3)

draw(
    Arrow(u, color=Colors.ORANGE),
    Arrow(v, color=Colors.PINK, linestyle=LineStyles.LOOSELY_DASHED),
    Arrow(add(u, v), color=Colors.BLUE)
)

The functions in the vec2d.math library are self-explanatory. Vectors are represented and tuples with int or float components.

The vec2d.graph is a helper library for graphing related capabilities for 2D objects. With it you can draw simple figures such as points, segments, polygons, and arrows on the 2D plane using Matplotlib as the backend in a very simple way and without any hassle.

The library exposes classes for the figures, an enumeration for the common colors, and a function draw to render the figures as Matplotlib plots.

Class	Constructor example	Description
Polygon	Polygon(*vectors)	Draws a polygon whose vertices are represented by the given list of vectors.
Points	Points(*vectors)	Represents a list of points (i.e., dots), one at each of the input vectors.
Arrow	Arrow(tip) Arrow(tip, tail)	Draws an arrow from the origin to the tip vector, or from the tail vector to the tip vector if tail if given.
Segment	Segment(start, end)	Draws a line segment from the start to the vector end.
