[x3d-public] X3DCanvas vs x3d-canvas, X_ITE - conversion stylesheet results

[Joseph D Williams]

>> "The longest dimension of the bounding box defines the S coordinates, and the next longest defines the T coordinates."

Hi Holger, I certainly agree with this, but not during animation. We would use the default mapping once, for the default pose, then the same after animation begins. Again, the way it is showing is a neat effect, but not realistic, since the texture should stay mapped to the default pose, not recomputed at each frame. 
Thanks, 
Joe

X_ITE does exactly what is documented here https://www.web3d.org/documents/specifications/19775-1/V4.0/Part01/components/geometry3D.html#f-IndexedFaceSettextureDefaultMapping to automatically calculate tex coords.

>> "The longest dimension of the bounding box defines the S coordinates, and the next longest defines the T coordinates."

In your example the longest dimension is as we can see the Y-axis, but the next longest dimension will change when the IFS is animated, sometimes it is the X-axis and sometimes it is the Z-axis. (You can see a flip)

Second, because the IFS is animated the tex coords will always change. (You see the texture moving)

Here are the lines how X_ITE does the calc: https://github.com/create3000/x_ite/blob/ad74f5212dae83c436bf0fc25eb4ac471301ae50/src/x_ite/Components/Rendering/X3DGeometryNode.js#L357

Please have a look at it. I cannot find a bug.

Best regards,
Holger

Notice how skin moves around with animations. 
I still think this is because browser does not honor textCoords, Do I need to make a change to get thisto work right when it works correctly in others. As I recall from past, xite doesn’t autogenerate texcoords and needs repeat for every point? 
Thanks, 
Joe

[related topic:  upgrading "X3D to X_ITE" stylesheet, to match your announcement]
 
Holger, thanks for all of the amazing work that you continue to accomplish.
 
After finishing much other work, I’ve finally been able to update the (newly renamed) X3dToX3domX_ITE.xslt stylesheet to support your use of <x3d-canvas> element.
 
Apologies for delays reaching this point.  The new version of X_ITE looks good!
 
Hoping that you can confirm I’m using your publishing patterns correctly.  Might you please check HTML/CSS source for the following developmental example.  If there are better ways of doing things please advise.

One thing I was not able to figure out… if you unzoom the JoeSkeletonSkinSiteSaluteWalkX_ITE.html page (using 4-arrow button in upper left) there is space for X_ITE Console, to appear as before in prior version.  However this feature is no longer working.  Am happy to correct it, or omit it, as appropriate.
 
         <div>
            <h3>X_ITE Console</h3>
            <p class="x_ite-console"/>
         </div>
 
Hmm, reviewing: another thing is that the stylesheet link is still there but without apparent harm.  Will try removing that later.
 
Having fun with X_ITE, X3D and HTML5!  8)
 
all the best, Don

With version 6.0.0, X_ITE uses the new element name <x3d-canvas>, lowercase and with dash. Because X_ITE uses the Custom Element API from JavaScript now. This has the advantages that the element can be created with document.createElement, and is then immediately ready to use :). Other advantage is that the CSS file must not be included anymore.
 
For compatibility the old name can still be used, but we encourage all users to update to the new tag name.
 
Best regards,
Holger
