Vector3D readme

Vector3D is a lightweight package, written on python, for working with vectors and points in 3D decartian system.

Installing

You can install vector3d from pip: python3 -m pip install vector3d or by downloading a .whl file from one of releases and installing it using this command: python -m pip install filename.whl or you should download a source .tar.gz archive from one of releases, unpack it and install with following command: python3 setup.py build python3 setup.py install

Reference

vector3d.vector

Implements the Vector class and vector related functions.

vector3d.vector.Vector

A vector class. Can be created as:

• Vector(x,y,z)
• Vector(x, y, z=0)
• Vector(x, y=0, z=0)
• or simply Vector() which is equivalent to Vector(0, 0, 0)

Functions in vector3d.vector

• from_point(a, b) - creates a vector from pair of points, begining and ending of vector.
• angle(a, b) - calculates angle between vectors a and b.
• horizontal_angle(a, b) - calculates angle between vectors a and b, but without Z coordinate (projections of a and b to XY plane).
• vertical_angle(a, b) - calculates angle between vectors a and b, but without X coordinate (projections of a and b to YZ plane)

vector3d.point

Implements a Point class and point related functions.

vector3d.point.Point

A class for the point in 3D decartian system. This class have only three attributes and: x, y and z coordinate of the point, and has no methods yet. A Point can be created with following constructors:

• Point(x, y, z)
• Point(x, y, z=0)
• Point(x, y=0, z=0)
• Or even Point() which is equivalent to Point(0, 0, 0)

Functions in vector3d.point

• distance(a, b) - calculates distance between two points
• center(a, b) _ calculates coordinates of the center between two points (returns a Point object)
