ABSTRACT. X3D version 4 is a major upgrade to the Extensible 3D (X3D) Graphics International Standard that supports HTML5 integration, advanced Physically Based Rendering (PBR) with glTF, Projective Texture Mapping (PTM), Humanoid Animation (HAnim2), integration with the Web Audio standard, and numerous other improvements. Available file encodings include XML ClassicVRML JSON and Turtle, and complete open-source programming libraries are available in JavaScript, Java, and Python. Strict validation of models allows exceptionally high levels of Quality Assurance (QA). This tutorial summarizes new capabilities and describes author support in modern browsers, updated tools and a growing set of examples. An emphasis on design principles illustrates how this important standard has steadily and consistently evolved for archival publication of interactive 3D graphics across the Web.
