A combination of Java-based playback and authoring technologies that enable any standard Web client with a Java Virtual Machine (JVM) to display interactive 3D graphics without the need for special plugins or downloads. Web clients with JVMs are presently found in a wide variety of information appliances, including handheld computers, set top boxes, PCs and computer workstations. Developed byShout Interactive, the highly optimized 3D rendering engine found at the core of Shout3D is written in pure Java (1.02) and comes complete with keyframed animation, physics and full extensibility via a set of robust APIs.
