Java3D installation (idea version)

During the period of learning computer graphics, the school chose the relatively unpopular Java3D, and there are few installation tutorials on the Internet. The installation tutorials are for reference only.

1. JDK installation

JDK click to download
You can download the stable version 1.8 or 11. Remember to configure the environment on my computer here. Because there are many tutorials, I will not repeat them here.

2. Java 3D 1.5.1

Click to download Java3d
Select according to your own system, for example, if I use windows, select java3d-1-5-1-windows-i586.exe (representing 32 bits)

Note here that the number of bits of JDK and Java3D needs to be the same , for example, JDK uses 32 bits, and the Java3D library also needs 32 bits.

3. Installation of idea

Idea click to download
to download the community version, if there is an activation code or other ways to download the ultimate version

After the above three installations are installed, you can open the idea for configuration

---

• ddl file configuration
  Copy the ddl file in the Java3D bin directory file to the JDK bin directory, otherwise an exception UnsatisfiedLinkError will be reported
  

• Open the idea, select the environment, create a project,
  right-click the environment under External Libraries, and open the library settings
  

• Add jar package
  

• Find the installation location of java3d, the default is to import the jar package in the following path
  \Java3D\1.5.1\lib\ext (64 version of Java installation path may not be (x86))
  
  
  

• Finally test the results with the code

package com.codeslogan.Test;

import com.sun.j3d.utils.universe.*;
import com.sun.j3d.utils.geometry.ColorCube;
import javax.media.j3d.*;
import javax.vecmath.*;
import java.awt.GraphicsConfiguration;

        // Create the TransformGroup node and initialize it to the
        // identity. Enable the TRANSFORM_WRITE capability so that
