Shape4D
About Shape4D
Shape4D is a tiny library for point, line and polygon in 3D space, as well as their simple relations.
Core Features
-
Shape classes: Point, Line and Polygon.
-
Creating a 3D polygon by defining a 2D shape in working plane at first and then moving it to its desired position.
-
It provides functions to judge whether a point is contained in a shape, either line or polygon, by overloading the magic function __contains__
.
-
__hash__
and __eq__
, overloaded for point, line and polygon.
-
__neg__
overloaded for polygon when one wants to know the vertices on its other side.
Requirements
-
Python 3
-
Matplotlib is installed.
Documentation

Installation
pip install Shape4D
Usage
import Shape4D.VisualShapes as vs
W,H = 2.0,1.5
shape = vs.Shape('rectangle',W,H)
shape = shape.move(to = (2,0,0), by = (45,30))
line = vs.Polyline((0,0,0),(3,1.,2))
P = shape.intercept(line)
line.broken_by(P)
shape.plot(hideAxes=True,style = {'facecolor':'cornflowerblue', 'edgecolor':'navy'})
shape.add_plot(line,style={'color':'k','linewidth':2,'node':'visible'})
shape.show(azim=-20, elev=3)
