[x3d-public] HAnim Features Points, 1-120 for your review

> A male model - well - that leaves out 50% of the population right there 

Hi Carol, It would be great to have two examples, one male and one female style. 
Of course there should be enough feature points on the surface to be able to dimension either presentation. Are there slightly different points of measurement for the typical male and female.
Seems like there should be more points for a female since, well, since different shape and relationship to shoulders and waist(?). 
Thanks,
Joe

My point is the following: it is not "a" male model, but "the" male model as the definite article (the) is used before a noun to indicate that the identity of the noun is known to the reader. The indefinite article (a, an) is used before a noun that is general or when its identity is not known. (yes, I had to look this up)

Expanding on this: The measurements are appropriate example for a male model drawn 1:1 scale as derived from a collection of actual measurements. The numbers are relative to 0 0 0 at the floor between the feet.  The measurements are appropriate example for the model that was drawn 1:1 scale with the known symmetrical body shape, as derived from a collection of actual measurements taken off of the virtual humanoid that is in the required I pose, in the x,y,z ordination as required by HAnim, with origin at 0,0,0 between the feet. 

A male model - well - that leaves out 50% of the population right there.  

I am not saying the translations are wrong - just more limited in actual application than first thought. So I can give more translations but I need a way to get the skin surface into Rhino.  If we can get the skin surface into Blender - from Blender, then save as an OBJ file that I can import into Rhino - I can get the translations.  But the underbust will be an approximation as there is no curve changes on the front side of the body.

Maybe we need to discuss this live to clarify some details. 

Thanks,

I have been looking into this.  And I am agreeing with John's assessment. I will somehow need to get everything into Rhino for visualization and coding. 

>From John on March 14th. 
I am thinking that humanoid_root and all other joint centers are relative to the LCS (local coordinate system) of the humanoid, which is 0, 0, 0 relative to any transforms outside the humanoid.
That's my best guess right now.

What is not noted on the General is the exact file or model for which these translations were built for.  This means that the list of the translations on the website only valid for the humanoid model that they were obtained for, the distance of that model from the origin and are not appropriate for Gramps or any other model. 

This means that for every joint center and every translation, it would be good to have reason for why is it located where it is.

Is this the model for which the translations are built for?  Can someone send me the proper link? Is this it?  I will see if I can import it into Rhino 8.

Back to updating every 120 points currently listed as to recommendations of how to locate it and adding the additional feature points that I have requested.

Great John,
I will check this out soon. 
Any ideas for the 'virtual' feature points? 
All Fine, 
Joe

Joe, do you mean user drawn, not in current standard? User defined points?  I have scripts for sites to place coordinates, but I don't have  a way to get them into the hierarchy yet, so...

Carol, I'm discovering it makes a difference where you put the Transform in the HAnimSegment as to whether to reuse the center.  I don't have something that doesn't put out warnings yet, or takes the Sites away from the Joints.  Hmm! 
My best Humanoid so far is Humanoid4J.x3d.

I'm going to get some sleep.

Thanks to Joe and Don for good examples to draw from!

No, I don't have any metadata yet.  Let's set up a time and figure out who all contributed.

You can make the skin opaque to see that I'm really grabbing this from a HumanoidAnimation/Skin/Joe*.x3d example, just my own incantation of scripts to draw the humanoid geometry.  I'll be checking those in soon.
