How to Create a ry model for a Java3D instance

Java3D, is relatively old technology, Java 8 Oracle JavaFX support Java3D. For information, refer to the Oracle official website <JDK8 has not officially released Early Access version of http://jdk8.java.net>

Environment to build a Java3D development environment, JDK download see the Oracle official website. After installation, find the Java3D driver package in the lib file under the installation directory, add your own project
