Our 3D cave models are now exported as VRML files. VRML stands for "Virtual Reality Modeling Language". It is a language designed construct and display 3D objects. It is especially useful for viewing 3D objects over the Internet. VRML images can use sophisticated modeling techniques including Gouraud Shading, spline surfaces, directional lighting, texturing and high-speed animation to display very realistic images. For caves, this allows the creation super-realistic looking cave passages.
