HumanoidAnimation (HAnim) X3D Examples Archive

The HumanoidAnimation (HAnim) X3D Examples Archive includes a growing number of humanoid models using joints, segments, skin, and animation behaviors.

Current work is upgrading all models to support ISO/IEC 19774 Humanoid animation (HAnim) International Specification, version 2.0.

Quality Assurance (QA) efforts are documented with diagnostics, warnings and error messages.

Also available: HAnim2 name / HAnim1 alias tables and HAnim2 default values for Joint, Segment and Site (feature point) nodes.

Facial Animation

Background. Computer facial animation is an area of current work for HAnim. Example models in this directory use the Facial Action Coding System (FACS) to provide Facial Animation examples. A variety of Action Unit (AU) enumeration values are defined for each facial expression in FACS. The FACS Visual Guidebook showcases the expressive power of this approach.

Initial examples. The original example models show basic patterns for modifying coordinates of a custom mesh. The Suwon VRLAB X3D Converter was used to compute CoordinateInterpolator animation values.

The README: Original FACS Models page describes the original contributions and subsequent X3D model refinements. The HAnim Facial Animation Design Patterns diagram illustrates these modifications.

Next steps. The Future Work: FACS for X3D HAnim page describes plans for continuing progress. Continuing refinement of animation models may lead to formally defining additional features and functionality in the Humanoid Animation (HAnim) International Standard.

Legacy

HAnim Legacy characters are HAnim1 X3D3 models conforming to version 1 of the Humanoid Animation (HAnim) International Standard, ISO—IEC 14774:2019.

Legacy models are not strictly valid as X3D4 HAnim version 2.0, since HAnim version 1.0 has significant differences and is no longer directly supported. There are a number of inconsistent overlaps between HAnim 1.0 and 2.0 that make things quite difficult to support both in the same codebase. Recommendation: convert legacy HAnim 1.0 models to HAnim 2.0 and validate first.

The earliest original model for skeleton and skin: originals/boxman.wrl, originals/boxman.js, and originals/boxman.x3dv.

Prior work converted HAnim1 models to HAnim2, testing X3D Quality Assurance (QA) conformance, and upgrading X3dTidy stylesheet cleanup capabilities. See build.schematron.log.txt and build.log.txt for current status.

Motion Animation

These Humanoid Animation (HAnim) example models illustrate conversion from BioVision Hierarchy (BVH) files for Character animation (such as 1.bvh). BVH files are often produced using Motion Capture (MOCAP) techniques.

The HAnim version 2.0 specifications are published and freely available:
