[semantics-public] [x3d-public] URL resolution problem on web3d.org - for X3D Ontology Assets; X3D Semantic Web meeting minutes

[Nicholas Polys]

Apologies, these meetings are not on my calendar apparently

but
I love this idea ~
my Master's student last year did a study with real scenes:

Feed Me: an in-situ Augmented Reality Annotation Tool for Computer Vision

https://vtechworks.lib.vt.edu/handle/10919/90897

 it was not X3D though... :-]
maybe we could try w X3D renderings and see how different objects
recognition techniques fare...
 ... would they match the X3DOnto description?
