Introduction to Programming with Java 3D
Java 3D is a new cross-platform API for developing 3D graphics applications in Java Its feature set is designed to enable quick development of complex 3D applications and at the same time enable fast and efficient implementation on a variety of platforms from PCs to workstations Using Java 3D software |
|
Getting Started with the Java 3D API
Java 3D is a standard extension to the Java 2 JDK The API provides a collection of high-level constructs for creating and manipulating 3D geometry and structures for rendering that geometry |

Getting Started with the Java 3D API
In Java 3D both interaction and animations are specified through the use of the Behavior class This chapter introduces the Behavior class and explains its use in interactive programs The next chapter Animation continues with animation examples and explanations 4 1 Behavior: the Base for Interaction and Animation |
Requirements
JDK version 1.5 or above (the examples use java 5 features)java 3d version 1.4 or above installedexperience with jfcbasic computer graphics knowledge (3d transforms, illumination types) dzone.com
Models
You can download free 3d models on websites like turbosquid or the 3d archive . Free models may not have the quality you are looking for, so if you are on a serious/commercial project, you should probably consider purchasing a quality model. If you really want to model your objects you can try blender. dzone.com
Visualizing The Model
I will use a cockroachI downloaded from the 3d archive. You can choose another model if you will as long you know what you're doing. I will use poseray to visualize the model. Poseray cannot open every 3d format, so if the format of your model is not supported by poseray, you will have to use some other program like 3dwin to convert it to a format
Loading The Model
Lightwave .lwo format Recommended reading: objectfile javadoc , lw3dloader javadoc . dzone.com
Basic Setup
Now that you know how to load the model let's see how it will look on your program before proceeding to further manipulation. the most important class of this example is the simple universe, which saves you from having to configure the view of your scene. a directional light is added to allow you to view your object (no light and you will see a pla
Getting The Scene Components
We need to obtain a reference to every body part we need to manipulate (or just scene component, if you are not using a model of an animal). If you want to create a variable for every component and assign a meaningful name to each one, you will have to know what name maps to what component. the following piece of code demonstrates how to list the n
Transformations
Basic transformation steps: 1. Add the parts you want to transform to a transformgroup ; 2. Apply the transformgroup.allow_transform_write capability to the group if it wasn't set; 3. Create or use some previously created instance of transform3d ; 4. Configure this instance of transform3d as / if necessary; 5. Apply this transform3d instance on the
Hierarchical Model
Now that you have access to all components separately, you can build your custom hierarchical graph. If you have been using swing or awt, you are already familiar with the hierarchical model. for instance, you can have a jframe , which then adds a jpanel , which then adds a jlabel and so forth. Many properties applied on the root are propagated to
Appearance
The loaded cockroach is quite pale since no material descriptors were associated with it, but this is not a problem, as you can define your textures for each component of your graph. you must read the material javadoc to understand what is being done here. To save some effort, I will declare some constants for ambient, emissive and specular light c
Lights
As you have seen, we still need to add two lights and one camera (a view). if you have read the , you have seen a directional light being added to the root of the scene. it's interesting to make the light go with the roach wherever it goes if you don't want it to get completely black after walking out of the reach of the light - in this case you wi
