[x3d-public] HAnim Examples

[Joseph D Williams]

Hi All, from what we were able to decide so far, the next step is to care for the web3D.org HAnim Archives. Lots is there and nothing is really been superceded, but plenty has been updated. There is duplication and some important items not adequately demonstrated.
So, the highlights are: 

Organizing Example Set:
More Tutorial Order of Appearance
Connections with other X3D Archives
All will be preserved and referenced

V2.0 Examples 
 (mostly evolved from v1.0)
 Basic Humanoid 
  skeleton-accessories-skin
 Basic Skeleton Animation
 Shared skeleton animations
 Segment Geometry 
  Geometry Animation
 Skin Geometry 
  Single Mesh - Multiple Meshes
 Skin Geometry Animation 
  Joint(s) to Point(s) with Weights
V1.0 and 1.1 Examples 
 All current examples 

So, the main idea is to cull through the V1.x examples and produce a nice set of v2.0 examples.
Some easily made from existing and some tune ups.

Additionally, there is this that needs to be advanced.

needs: 
* Integrate loa4
* Working Mocap conversion (in x3dEdit)

Basic Tutorial Structure: 

Prerequisites
# basic X3D user code and event system 
# Transform: orientation and rotation
# parent/child hierarchies
# timer, orientation interpolators

Comment: Nothing Really Special Here.
Since the entire reason for the rest of X3D is to produce and interactive environment for the interactive humanoid, all the basic building blocks for HAnim are mostly already there.
 Standard X3D
  All Structures and Functions are Human Readable
  Realistic Model: 
   X3D Medical/Physics Integrates as Expected 
 Best Practices:
  Medical/Personal Orientation 
  Late 20th Century Animation Industry Agreements
  Emphasis on RealTime but readable Data and Structures 
 Under the Covers, All same

Tools:
Simple Text Editor
Stand Alone or HTML Canvas 
Free Open Authoring/Runtime Tools
Commercial/Hobby
X3DEdit
X3dToXhtml.xslt 
X3D Validator
X3D Tidy 
X3D DTD, X3D Schema, X3D Schematron
 Document and Analyze Joint. Segment, Site names and hierarchies

Outline:
Example Standard Realistic Humanoid 
 Standard Basic Initial Pose (prior to Animation)
 Joint hierarchies
 'standard' Joint Center locations 
 'standard' Joint Functionalities
 'standard' Site locations
Example Joint center and Site locations
Skeleton hierarchy and site coding example
Skeleton Animation (ball and stick)
Sharing Animations 
 Same Skeletons 
 Similar Skeletons
Add Segment geometry 
 Proper Parentage
Viewpoint examples Parent, Humanoid, Site(s) 
Use Displacer(s) with Segment Geometry
 Displacer Bindings: 
  points-displacements-scaling
Sites: Shapes-Sensors-Viewpoints
Add Skin Geometry 
 SIngle Mesh - Multiple Meshes
 Skin BIndings: 
  points-Joints-Weights  
Use Displacers with Skin geometry
Non-standard Initial Pose
Prototype Joint/Segment/Site nodes

Motion Capture
 Capture Skeleton
 Performance Skelton 
 Joint Rotation same as Segment Orientation 
  (if skeleton’s structure is correct)
 Data Transport 
  (Whatever to X3D) 

Parent space
Humanoid space
Skeleton space
Segment space
Site space
Skin space
Works Best When all spaces are same space

> From Don: 
Next we will resume weekly efforts to:
- Review existing examples in Basic archive 
  https://www.web3d.org/x3d/content/examples/Basic/HumanoidAnimation 
- start a new HAnim model archive (as long expected)
- copy and check and correct all HAnim1.1/X3Dv3.3 examples
  (reconciling prior incorrect HAnimHumanoid version numbers)
- copy and update relevant examples for HAnim2/X3D4
  (some repetition expected between legacy models and new models)
- copy, analyze, correct (if needed), and maintain all specification examples
- add HAnimMotion examples
- review and admire

Let's talk about it
Thanks and Best, 
Joe

Location: X3D zoom line

Joe and Don have reviewed HAnim v2 specification and corresponding X3D4 references.

"We went in and came out, miraculously emerging again!"

Next we will resume weekly efforts to:
- Review existing examples in Basic archive 
  https://www.web3d.org/x3d/content/examples/Basic/HumanoidAnimation 
- start a new HAnim model archive (as long expected)
- copy and check and correct all HAnim1.1/X3Dv3.3 examples
  (reconciling prior incorrect HAnimHumanoid version numbers)
- copy and update relevant examples for HAnim2/X3D4
  (some repetition expected between legacy models and new models)
- copy, analyze, correct (if needed), and maintain all specification examples
- add HAnimMotion examples
- review and admire
