Thanks Joe. First, found and fixed a twisted redirection link on website. Here is corret link for HAnim archive:
[0] HumanoidAnimation X3D Examples Archive: 6 Directories, 63 X3D Models
https://www.web3d.org/x3d/content/examples/HumanoidAnimation
Next, here are the "knobs we can turn" for archive design:
a. adding evocative images for each directory is definitely doable - once we get directory categories decided.
Scroll down top page of other archives to see examples:
[1] Extensible 3D (X3D) Graphics: Basic Examples Archive: 27 Directories, 784 X3D Models
https://www.web3d.org/x3d/content/examples/Basic
[2] VRML 2 Sourcebook X3D Examples Archive: 31 Directories, 416 X3D Models
https://www.web3d.org/x3d/content/examples/Vrml2Sourcebook
[3] X3D for Web Authors (X3D4WA) Examples Archive: 16 Directories, 268 X3D Models
https://x3dgraphics.com/examples/X3dForWebAuthors
[4] X3D for Advanced Modeling (X3D4AM) Examples Archive: 17 Directories, 118 X3D Models
https://x3dgraphics.com/examples/X3dForAdvancedModeling/
Another archive that needs images:
[5] ConformanceNist X3D Examples Archive: 13 Sections, 66 Directories, 761 Models
https://www.web3d.org/x3d/content/examples/ConformanceNist
(Good opportunity to help, if anyone wants to select images of best interest.)
b. Can subdivide examples in a different way if desired. Here is current lineup:
Characters
Legacy
Polygonal
Prototypes
Specifications
Templates
and awaiting content:
Medical
Motions
Organs
Skeleton
Skin
