[x3d-public] HAnim implementation minutes 2 July 2020, substantial progress

[Joseph D Williams]

➢ .  Joe, does this actually match LOA-3, for Joint nodes at least?

This is the v1 loa3 Joint hierarchy, but since I was just interested I the skin there is only a Segment where I wanted to attach something, like a camera or the coordinate art. Nor are there many Site objects. All the v1 loa3 sites are not Site nodes, but are points of the skin field geometry. I’m looking for a verdion of this that actually includes all v1 loa3 features and skin, it was in that crowd group. Like just adding the skin to our v2 spec visible model. 
Thanks and Best, 
Joe

Correct, the statistics table shows only one HAnimSegment is included.  So the tree matches the content.
