Shape4D 0.2.8

A small library for visible 3D shapes

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.

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)
