In the fast development cycles of today's technology world, complexity is in and of itself something to be avoided where possible. Power and flexibility come at the price of complexity.
OpenGL's exposure of the inner details of the rendering process can significantly complicate otherwise simple 3D graphics programs While C interfaces to OpenGL are ubiquitous, Java interfaces aren't yet standardized and aren't widely availableĪrcane Technologies's Magician product had until recently been in the market to change this portability issue, but with its demise goes much of the cross-platform story for Java-OpenGL, at least at present. Java 3D's more general-purpose optimizations mostly aim to maximize the portability of Java 3D applications. As with all hardware optimizations, you must use accelerator-specific OpenGL optimizations with the understanding that each optimization for one platform diminishes portability and performance for several others. It is in each vendor's best interest to build proprietary extensions and make proprietary optimizations to sell more of its own hardware. Many vendors' OpenGL optimizations are meant to decrease hardware choice The strengths of the procedural approach to graphics programming are simultaneously a weakness for many Java programmersįor relatively new programmers, many of whom may have received their first formal programming instruction in Java using object-oriented methodologies, OpenGL's procedural method does not mesh well with an object-oriented approach and good engineering practice. OpenGL, and certainly Java-OpenGL bindings, do have some significant shortcomings: As Microsoft has joined with SGI in the Fahrenheit initiative, it has become increasingly obvious to many that this is in effect Microsoft's indirect acknowledgment that OpenGL won the API wars for 2D and 3D graphics. Standard against which hardware vendors measure their graphics technology, bar none. Vendors of every kind of 3D graphics-related hardware support OpenGL OpenGL is optimized in hardware and software and targeted platforms ranging from the cheapest PCs and game consoles to the most high-end graphics supercomputers. OpenGL is optimized in every imaginable way One doesn't just hint and request as with Java 3D, one stipulates. OpenGL empowers programmers to directly specify how graphics should be rendered. This is true with any of the various language bindings, including most Java bindings. OpenGL provides direct access to the rendering pipeline The procedural model is at once intuitive and straightforward for many accomplished 3D graphics aficionados. This closely matches many of the algorithms and methods graphics programmers have used historically. OpenGL provides a procedural model of graphics
