Purpose of X3D
Submitted by Leonard Daly on Sat, 10/15/2016 - 20:33X3D and VRML have been an international standard since 1997. They define a means to model and texture 3D geometry, animate it, and provide user interaction. As an International Standard (VRML: ISO/IEC 14772, and X3D: ISO/IEC 19775-19777) these have provided extraordinarly stable and long-lasting formats. Content developed 20 years ago still runs today. That is an important legacy that should not be lost. At the other end of the timescale (today), there are environments and capabilities that could not have been imagined when the first standard was approved. X3D needs to keep a foot in the ancient past (as far as computer time goes) and current so that history is not lost.
