[x3d-public] New description fields

Thu Feb 9 10:44:51 PST 2023

➢ Otherwise X3D browser doesn't know what do you mean --
what texture coordinate is supposed to be associated with vertex with
index 9.

Yes it does, or it should. Just reuse the last set on the list to fill out the list. 
What is so bad about that? 
 Do you fail if not enough colors? 

Anyway, the Displacer is not working in 4.3.0 with no errors on that. 

https://www.web3d.org/x3d/content/examples/HumanoidAnimation/Skin/JoeKickIndex.html

Also, the item about the route statements being in a place you don’t like did not get fixed in 4.3.0.

Can you or someone please help me with <TextureCoordinate point='0 0 0.5 0.5 0.5 0 0 0.5'/> since I an’t seem to get the right number for happiness even when it seems right and works elsewhere.

X3D: Invalid number of items in a normal or texture coordinate array for shape "Joe_Humanoid:Joe_Kick:Joe_Shape:IndexedFaceSet(Joe_skin_IndexedFaceSet)": Invalid index: 141, but we have 139 items

Even when the numbers match at the correct numver ofverts it fails. 
Is this finding something in the texture transform? 

Sure would like to see Displacer working.

Thanks,
Joe

Yes :) I know we had a few communications about this already, so maybe
you already fixed it in some version of the file and it is just not
updated on that page.

I just report that

  http://www.web3d.org/x3d/content/examples/HumanoidAnimation/Skin/JoeKick.x3d

still has this error. Specifically, it contains geometry like this:

          <IndexedFaceSet DEF='Joe_skin_IndexedFaceSet' coordIndex='0
9 5 -1 0 7 9 ...' creaseAngle='3.14'>
            <Coordinate DEF='Joe_SkinCoord' point='0.0 1.77 ..../>
            <TextureCoordinate point='0 0 0.5 0.5 0.5 0 0 0.5'/>
          </IndexedFaceSet>

So you use coordinate index "9" (and larger, later, like 386) ... but
your "TextureCoordinate.point" has only 4 items. So you can only use
indexes 0..3. Otherwise X3D browser doesn't know what do you mean --
what texture coordinate is supposed to be associated with vertex with
index 9.

Michalis

See links below for X3D4 tooltips specifics.  The issue with view3dscene stems from adding a description fields in X3D4 using X3D-Edit (for the most part).  There are also schema issues with the file in question (JohnJoint18.x3d).
