VRML is text file format Which able to design vertices and edges for 3D polygon with any of the specified color. It is also used to perform UV mapping which create the 3D models of the 2D image. VRML files are commonly called with a name of “worlds” and have .wrl extension. VRML worlds contain the text format so that it easily compressed by using the gzip and compressed file transfer through internet more quickly.
VRML architecture include the Input processor, Simulation processor, Rendering Processor and World Database. Input Processor is used to control the input information to the computer e.g. Keyboard, mouse, 3D position trackers and a voice recognition system. Simulation Processor is the heart of Virtual Reality system. It takes the user input along with a number of task that are programmed with it and determine the actions that will take place in the virtual environment. Rendering processor is used to create sensation that are output to the user. World Database is also known as World Description Files. It store the objects that describe the actions of all those objects.
VRML is successfully used in various field like Entertainment, Medicine, Manufacturing, Education and training. In Entertainment, it is helpful in designing a more attractive and exciting virtual environment. In medicine, used to perform the practice test of surgery, surgery on remote patient and teach new skills in a safe, controlled environment. In manufacturing, used to make a low cost and highly efficient products. In education and training used to driving, flight, ship and tank simulators .
