Engine 3D

Francesco Forcellato

This project allows to create solids and display them into whatever you want. This project was inspired by a project created by Daniel Shiffman in Processing but I have made it in the standard Java, so no extra Framework needed.

Installation:

If you only want the compiled code, in order to add this library to your Java project, download Engine3D.jar.

Note: in order to run the Example you must import Engine3D.jar in the libraries.

Classes

• Engine.java class used to interact with a Solid and display it.
• Graph.java class used to create a graph of the connections in order to connect multiple nodes to each other.
• Matrix.java it contains all the methods used for managing matrices multiplications.
• Point.java class used to represent a 2D point.
• Point3D.java class used to represent a 3D point.
• Solid.java class used to create a Solid

Classes usable

To use this Java Library you must at least use an Engine object and a Solid object. The Engine controls the representation of the Solid, so you must create a Solid and add nodes to it, then you can add connections between the nodes.

To display the Solid you have to implement these methods in the Engine object:

• drawLine(double x0, double y0, double x1, double y1, Object drawer); which allows drawing a line between two points.
• beginPath(Object drawer); which allows beginning a path (requested from some components like GraphicsContext of JavaFX)
• closePath(Object drawer); which allows closing a path (requested form some components like GraphicsContext of JavaFX)

UML diagrams

Thanks also to @davideporcu for helping me to realize this diagram.

Versions:

V1.0.0

• Create a solid by adding nodes and connections between them.
• Rotate a solid by X-axis, Y-axis, Z-axis.
• Display a solid by implementing the drawing functions.

V1.0.1

• Added a project example using JavaFX.
• Change the location of the function makeCube(double size), now it is in the Solid class.
