J/View3DPro Technical FAQs  

The following are some general FAQs for J/View3DPro. If you need installation help, go to J/View3DPro Installation Instructions.

Do I have to know Java 3D to use J/View3DPro?
No, a little Java programming experience is all you need.

Do I have to be a Java programmer?
Some Java programming experience is needed. J/View3DPro consists of Java classes so you can not directly use J/View3DPro from C or C++.

What other software do I need to run J/View3DPro?
You need J2SE 5 SDK or newer and the Java 3D 1.5 Runtime envrionment. Go to http://java.sun.com to download J2SE 5 and Java 3D. For Linux, you can find Java downloads at www.blackdown.org

What hardware do I need to run J/View3DPro?
Any machine that can run Java 2 and Java 3D can run J/View3DPro. On Windows, there are two versions of Java 3D, one that is implemented on top of OpenGLTM and one that is implemented on top of DirectXTM. We recommend that you use the OpenGL version as it seems more stable. To get optimimum performance, make sure you have a 3D card with an up to date version of the OpenGL driver. Implementations of Java 3D for platforms other than Windows are all based on OpenGL and so the OpenGL runtime environment is a requirement.

After I download J/View3DPro, how do I get started?
After installation, take a look at the demos and read the tutorial in the docs directoryl. Then you are ready to start developing your own applications with the help of J/View3DPro's API.

What are the dispose( ) methods used for?
Dispose( ) methods are similar to class destructors. Dispose ( ) methods are used when resources need to be freed but there is a reference to the object that would prevent the object from being destroyed. Dispose ( ) methods have good uses, but they can be a sign of poor design.
