Thanks again for careful scrutiny and analysis.
I think we did not implement X3DTimeDependentNode interface because
startFrame/endFrame are used instead of startTime/endTime, so there is a
different field signature. Frames are certainly different than times.
However we might provide pause, resume inputOnly fields to HAnimMotion, as
corresponding to pauseTime, resumeTime in X3DTimeSensor. Suggested
improvement:

Have updated HAnim2.1 issue Mantis 1415 accordingly to keep track with this
discussion.

* https://www.web3d.org/member-only/mantis/view.php?id=1415
Also likely need pause and resume fields (corresponding to
X3DTimeDependentNode pauseTime/resumeTime) with further descriptive prose as
well.

We will need to perform a careful scrub comparing X3D4 best practices for
HAnimMotion when updating future HAnim2.1 specification fields and
descriptions.
https://www.web3d.org/x3d/content/X3dTooltips.html#HAnimMotion
Comments welcome. If agreeable, such an improvement (adding HAnimMotion
pause/resume fields) seems like a worthy best-practice addition for X3D4.
Also please confirm, do you think that there are any “showstopper” errors
for interfaces in current X3D final IS.proof version? Seems workable to me
…
all the best, Don

I took the opportunity to look at HAnimMotion in
https://www.web3d.org/specifications/X3Dv4Draft/ISO-IEC19775-1v4-IS.proof/Pa
rt01/components/hanim.html#HAnimMotion
and
https://www.web3d.org/documents/specifications/19774/V2.0/MotionDataAnimatio
n/MotionNodes.html
The question was how to actually play an animation described in an
HAnimMotion.
HAnimMotion is described as an alternative parallel to HAnim motion
data animation using interpolators which suggests driving it through a
TimeSensor.
However, fields such as frameDuration, cycleTime or timeElapsed imply
that the object is responsible for both playing the animation and
storage of animation data. But playing the animation is not explicitly
explained.
Here is my interpretation of the silence of the spec. on actually
playing an animation:
When does an HAnimMotion start to play ?
Presumably, the conditions are:
enabled and HAnimHumanoid.motionsEnabled are true
at least one channel is enabled
frameIncrement > 0
startFrame < endFrame if loop = false, or loop = true
When does it pause ?
frameIncrement = 0
perhaps other conditions
When does it stop ?
enabled or HAnimHumanoid.motionsEnabled are false
all channels are disabled (perhaps rather a pause?)
frameIncrement < 0, forbidden but needs to be handled
startFrame > endFrame and loop = false
Is there a concept of an HAnimMotion being activated versus enabled ?
The case of all channels being disabled could be interpreted as a
playing, but static animation showing untransformed joints. This would
remove channel state as a condition above.
Presumably, an implementation could construct internal Interpolators,
TimeSensors and Routes for fairly complete coverage.
Something like:
Timesensor: duration = frameDuration * frameCount, loop = loop,
shorten to represent endFrame
Each Channel is an Interpolator: ARotation = OrientationInterpolator,
APosition = PositionInterpolator (combine sequential rotations or
positions into single Interpolator keyValues). keys are 0,
frameIncrement, 2*FrameIncrement .. frameCount or so.
Routes: from Timesensor to CombinedInterpolator to joint
The signature in
https://www.web3d.org/documents/specifications/19774/V2.0/MotionDataAnimatio
n/MotionNodes.html#MotionObject
is missing startFrame and endFrame although the description then
includes these fields. The tooltips noticed this.
What is the order of application of transformations described in
channels: presumably, left to right ? Rotations are sometimes applied
right to left.
There is no scale channel ?
Some thoughts,
Andreas

I have taken
https://www.web3d.org/x3d/content/examples/HumanoidAnimation/Specifications/
KoreanCharacterMotionAnnexD01JinIndex.html as working model to implement
HAnimMotion. I have successfully created all interpolators, and if I
simulate a run of these interpolators they play a nice animation.
What I do miss in HAnimMotion are startTime, stopTime, maybe pauseTime,
resumeTime, isActive, isPaused fields from TimeSensor to start an animation.
Although HAnimMotion has next and previous input fields, but as far as I
could read from the specification, these fields are only for stepping
through the animation frame by frame.
There is another field frameIndex, when receiving an event, the
interpolators should jump to this frame.
But with these existing fields no nice transitions from one frame to another
can be made.
On the other hand it exists a elapsedTime field, but when nothing can be
started this field would not output anything.
With the still missing TimeSensor fields, this would be possible. Going now
a step further HAnimMotion can be derived from X3DTimeDependentNode, which
will now make much sense.

Hi Holger,
I was able to run the bvh example when converted to x3d back when a long
time ago. In Part 2 of
>From what I remember on this is that the source bvh animation only specifies
a frame rate, or number of seconds between samples. So the x3d import must
create a set of keys and organize the keyvalues. Since the keys are at the
video frame rate, the key field gets very tedious. Also, the number of
keyvalues goes up fast with skeleton parts, since there tend to be most
likely too many keyframes (in angles). Finally, this massive list of keys
gets duplicated for every interpolator.
With this, how much greater could we possibly honor developers of
interpolators and implementers of vrml and x3d interpolators than to somehow
allow a way to ?DEF? a key field and reuse it in another interpolator. This
would at least consolidate the code so could stand a chance to work on it.
Of course great number of key steps is not a issue for tools that just make
video because they only make fixed steps to render the specific key and don?
t interpolate.
Good Luck, Don has worked on this a lot including import of bvh skeleton and
animation directly to HAnim. Most of the bvh speaks bones while x3d speaks
joints. Remember, data for bone goes to parent joint.
Thanks,
Joe

I am not really clear how to start the animation of a HAnimMotion. I am
very hung up on how a TimeSensor works.
My understanding so far is that the animation is started when the
HAnimMotion receives an enabled=true event and then runs to the end or
starts over when loop=true.
I also guess that the next and previous events only have an effect if
enabled=false, otherwise it wouldn't make sense with the previous
assumptions.
I would be very happy if there was clarification on this.

You can get the same report from tovrmlx3d.exe, I think Don, see:

1. Michalis, thanks for a great trouble report.
I believe the conversion errors are now fixed in X3dToVrml.xslt

Unfortunately I discovered that a lot of type checking within that
stylesheet isn?t really effective due to a puzzling logic error, so there
may well be other errors like this. More work will likely be needed.
Wondering if you have a command-line mode for validating VRML/ClassicVRML
models with view3dscene? Perhaps I might be able to add that to our
regression testing build scripts.
2. Joe, it's your model, so please send any texture coordinate changes you

Meanwhile there are plenty of warnings from Schematron. They seem
accurate. The flagged parent-child relationships are either a problem in
the model, or else (less likely) a problem in the diagnostics (which are
autogenerated from X3DUOM).
I thought that possibly they are related to your use of loa=?3?
complexity, but diagnostics looked the same for loa=?4?.

Subject: [x3d-public] JoeKick H-Anim example - error in X3D classic
encoding
"Joe Kick" example linked from
https://www.web3d.org/x3d/content/examples/HumanoidAnimation/ ,
https://www.web3d.org/x3d/content/examples/HumanoidAnimation/Skin/JoeKickInd
ex.html
, 2 errors:
1. The "ClassicVRML" encoding version (
https://www.web3d.org/x3d/content/examples/HumanoidAnimation/Skin/JoeKick.x3
dv
) seems to be incorrectly converted from XML to classic encoding. It
contains
"""
DEF Joe_skull_tip_raiser_action HAnimDisplacer { coordIndex 0 1 2 3 4 5 6
7 8 9 displacements 0 0.15 0 0 ...
name "skull_tip_raiser_action"
}
"""
so the coordIndex and displacements fields miss [ ] around their values.
"coordIndex" is MFInt32, "displacements" is MFVec3f, they both require [ ]
in classic encoding if you want to have a list of arbitrary number of
elements. If no [ ] are used, the classic encoding parsers have to assume
they contain 1 item (1 integer on "coordIndex", 1 vector == 3 floats on
"displacements"). Currently parsing this fails, as parser sees unexpected
numbers in the middle of HAnimDisplacer.
This problem is not present in XML encoding, where no [ ] are used, the
lists are in separate XML attributes.
2. The XML encoding version contains invalid number of texture
coordinates, we have discussed in previously on this list:
X3D: Invalid number of items in an attribute array for shape
"Joe_Humanoid/Joe_Kick/Joe_Shape/IndexedFaceSet(Joe_skin_IndexedFaceSet)":
Invalid index: 9, but we have 4 items in 2D texture coordinates

Michalis
