# VisualShape3D
## VisualShape3D
VisualShape3D is a simple library of geometry designed to quickly build a 3D model with its functions. It starts with creating a viewport at first, followed by adding each 3D shape to it, and finally showing them all at once. There are three shapes: Point, PolyLine, and Polygon. A 3D polygon is created by first defining a 2D shape on the yz plane and then transforms it with both new position and orientation, while its bottom is limited to motion in XY plane.
As seen in the following examples, VisualShape3D is capable of calculating line intersections with polygons, as well as rotating/translating a shape to building a 3D body.
## Core Features
* Shapes : Point, Polylines, and Polygon.
* It can check whether or not a point is inside a segment or polygon.
* __hash__ and __eq__, also overloaded for ordering and logical equal the three shapes.
* For a shape, __neg__ is overloaded for one to get thevertices in the order viewed from its other side.
## Requirements
* [Python](http://www.python.org) 3
* Matplotlib is needed.
## Documentation
To be continued.
## Installation
```bash
pip install VisualShape3D
```
## Usage
* case 1 : building a box.
