[x3d-public] Turning on and off simultaneous animations individually

Sun Feb 16 09:03:53 PST 2025

I think that menu needs to be made as a HUD (see jin animations menu) so the menu stays in view when navigating, even just bringing the face closer. 
For that, ProximitySensor needs to work. x3dom? 
Thanks,
Joe

Yes, at the bottom of the emotions menu.

This is great step. Is there a stop, reset all anims button?

Hi,

the x3dom editor now uses an experimental version with much improved performance for HAnimDisplacers:

https://andreasplesch.github.io/Library/Viewer/index.html?url=https://raw.githubusercontent.com/coderextreme/ci2had/refs/heads/main/resources/CleanedYouClocks.x3d

This experimental x3dom version is available at

https://andreasplesch.github.io/x3dom/dist/

Feel free to use and test it. Some tests are available at

https://andreasplesch.github.io/x3dom/test/

Have fun, -Andreas

Hi,

I took a first stab at Displacers in Segments for x3dom and use it now in the editor:

https://andreasplesch.github.io/Library/Viewer/index.html?url=https://raw.githubusercontent.com/coderextreme/ci2had/refs/heads/main/resources/ManyClocks.x3d

This is experimental and mostly for testing purposes. If there is an example combining Displacers in both Joints and Segments that would be interesting as it is not necessarily expected to work.
The experimental implementation is inefficient and expensive as it is weight_changed event driven. If you activate multiple displacers the frame rate starts to drop. It probably is not very useful at this point.

Fee free to give it a try, -Andreas

Hi John, 
Thanks. I found the tongue.x3d example but if you can create another one that would be helpful in general. 

You vastly overestimate my ability and availability ;) This would be a longer term project. I have an idea what to do.

I had one I sent to Holger, probably derived from this one:

https://github.com/coderextreme/ci2had/blob/main/resources/JinMouthStretch.x3d

What I would do (again) is take out all the segments but the tongue.

There’s no menus involved in this one.

If you need further assistance, like a smaller example, I can help.  Also all the Jin*.x3d FACS action units can also provide examples.

I’ll be pretty unbusy today.  I can allocate some time for creating a model, make sure it animates, etc.

If you’re able to allocate some time today, great, we have an HAnim meeting tomorrow and showing off X3DOM editor using Displacers would be fantastic!

Remember there’s a coord field in HAnimSegment that the HAnimDisplacer operates on!

Hi John, 
The reason is that Displacers are currently implemented in x3dom only for Joints, but not for Segments, unfortunately. Do you know of a simple but instructive test case of Segments with Displacers ?

I will try to test this in castle model converter.

I did try setting a value for the outputOnly fields, but the converter wouldn’t shut up.

The model below doesn’t seem to animate when one presses the menu items.  Did you get it to animate?

Hi John, all,

It turns out that x3dom currently expects a default value for Proto fields even for outputOnly fields. This is due to how Proto fields are initialized. They always need to have a value. While the spec. does not require this, it seems still good practice to always define a default value in the ProtoInterface. There may be a case where an outputOnly field is used in ISing where a valid value would be expected. There may be other corner cases.

Here is your example with added default values for outputOnly fields:

https://andreasplesch.github.io/Library/Viewer/index.html?url=https://gist.githubusercontent.com/andreasplesch/af5ff3148c1159f71d34fb78c1f63024/raw/b3d4470107ab74e301ed48448ab2a4f4154672e0/ManyClocks_John.x3d

This could be fixed in x3dom, by always setting some default value. Is there a list of recommended defaults for each data type if no other source of defaults is available? For SFTime it seems to be -1.

Andreas, "startTime" is an accessType outputOnly field, so why do I need to provide a value attribute in fieldValue?  I'm kind of confused.  I'm probably missing something in the spec.

You are right, I only outlined scenarios where the accessType allows input or initialization..
In the outputOnly case it is not necessary to provide a fieldValue node at all since there is no value which can be provided. Providing the node would indeed be confusing, to both the user code reader and any X3D browser.
I believe the spec. is silent on this case in any encoding.

Best, Andreas

Thanks for any clarification.

I have finally enabled schematron on the project, but I'm finding it hard to understand the messages, and modifications that I make, while removing the immediate problems, seem to move the problems elsewhere.

Explaining why I need a "startTime" fieldValue value is my main lack of understanding, but perhaps I need a whole review of accessType.

Castle Model Converter reports:

castle-model-converter: Warning: X3D: X3D XML: <fieldValue> element references unknown field name "enabled"
castle-model-converter: Warning: X3D: X3D XML: <fieldValue> element references unknown field name "startTime"
castle-model-converter: Warning: X3D: X3D XML: <fieldValue> element references unknown field name "stopTime"

I will try providing a field value in the ProtoInterface

If I "cleanup" enabled, startTime and stopTime, I get:

castle-model-converter: Warning: VRML/X3D: Within prototype "MenuItem", event "inputTrue" references (by "IS" clause) non-existing event "enabled"
castle-model-converter: Warning: VRML/X3D: Within prototype "MenuItem", event "triggerTime" references (by "IS" clause) non-existing event "startTime"
castle-model-converter: Warning: VRML/X3D: Within prototype "MenuItem", event "triggerTime" references (by "IS" clause) non-existing event "stopTime"

I guess what I conclude at this point is, startTime and stopTime are bad DEF names, but what about enabled as a field?  The dominoes are falling.

About your two scenarios in the other message, perhaps this is revealing.

See attached attempt to fix original issue, which resulted in the above.

I think x3dom, reasonably, expects a value for the fieldValue nodes:

For example:

<fieldValue name="startTime" /> 
and others.

Andreas, Joe,

Reset Button, Reset_Clock added.

See attached zip for details, or visit link;

https://create3000.github.io/x_ite/playground/?url=https://raw.githubusercontent.com/coderextreme/ci2had/refs/heads/main/resources/CleanedYouClocks.x3d

For some reason, this link doesn't show the live scene?

https://andreasplesch.github.io/Library/Viewer/index.html?url=https://raw.githubusercontent.com/coderextreme/ci2had/refs/heads/main/resources/CleanedYouClocks.x3d

Puzzled, haven't researched it yet.  Looks good in Sunrize and X_ITE, will try FreeWRL next.
