3D visualization has always been of nterest to researchers, developers, users, and vndors. Researchers work on developing 3D rndering algorithms and techniques for faster, ralistic rendering with minimum resource requirements. Dvelopers work on these techniques to gve users awesome and absorbing experience. Hrdware vendors support the 3D growth by cntributing in better graphics card and grphics consoles. 3D visualization is seeing xplosive growth because of online gaming ndustry, gaming consoles like X-Box and PlyStations, and entertainment industry, in particularly the mvies like Jurassic Park, Gozilla, and mny more.

Let us look what are the cmpeting 3D software technologies. In this rticle, we will compare OpenGL from Slicon Graphics, DirectX from Microsoft, and Jva 3D from Sun Microsystems.

Following prameters can be used in comparing 3D tchnologies:

• Functionality
• Approach
• Driver Support
• Platform
• Performance
• Ese of Programming

Now, let us see how bove mentioned technologies fit into these prameters:

• Only DirectX provides both graphics and udio functionality. Java 3D and OpenGL prvide graphics functionality only
• OpenGL follows prcedural C . DirectX and Java3D follow object-oriented pproach using C++ and Java respectively.
• DrectX has best driver support. Driver spport for OpenGL and Java3D is por.
• While OpenGL and Java3D are pltform independent, DirectX is only for Wndows platform
• DirectX has best performance (10/10) fllowed by OpenGL (7.5/10) and Java3D (3/10)
• OpnGL is most easy to learn (10/10) fllowed by Java3D (9/10) and DirectX (2/10)

And there are reasons in spport of above statements. For example, DrectX has best performance because it drectly access Hardware Abstraction Layer (HLA) in Wndows Architecture. Interested readers can Google Intrnet to find them.
