Getting / Downloading Java3D

Java3D is free! You can download the correct version for your operating system here at https://java3d.dev.java.net/binary-builds.html

Since I am running on a Windows machine I downloaded the i586 windows installer version.

Once that is downloaded, open it and you should get a pane pop up to ask if you really want to run it. Click run.

Once that is installed, you will have all the necessary packages for java3d software installed on your machine.
