If the HAnimJoint DEF names are the same, it should be simple to use the current example animations to control your characters.<div class="im"><br>

If Don can't see the file and troubleshoot, he can't fix X3D Edit.<br>
<br>
I suggest sending me a file for one of the characters so I can take a look and perhaps help identify details needed to reuse the example animations with your characters. Please send me .x3d file to read. I will report back as soon as I can.<br>
<br>
Thanks Again for your important work.<br>

Dear Joe,<br>
<br>
Thank you for your comments.<br>
<br>
Our 10 example X3D H-Anim characters were first designed with 3ds MAX then<br>
converted from WRL files to X3D files. Our method for their design can be<br>
applied using many other tools in the same manner, as long as those tools<br>
support WRL files. Our viewer includes the conversion function, wrl-to-x3d<br>
(hanim).<br>
<br>
The X3D files are readable text files.<br>
X3D validation for all the X3D files was completed a while ago, as I<br>
presented them at previous Korea chapter meetings, as well as at SC24<br>
meetings.<br>
<br>
The 10 characters can also be displayed in the BS Contact viewer.<br>
However, X3D-Edit does not display the characters correctly (it displays<br>
just a black scene).<br>
We are testing if the 10 characters can be animated using the same<br>
interpolators as used for Allen and Nancy.<br>
However, it is not easy and very complex to apply those interpolators to<br>
other character models, including ours.<br>
This is our dilemma, but we must figure out how to apply the interpolators<br>
of one character to other characters.<br>
<br>
I am looking over the work that you and Don have done recently by going<br>
through the emails.<br>
Thank you for sending all the information.<br>
I will ask questions later if there are problems to discuss.<br>
<br>
Sincerely,<br>
<br>
Myeong<br>

Thank you for this. I think it does not matter which tool the author uses<br>
in design and animation, it is the actual human readable X3D HAnim user<br>
code that represents each character that is of primary importance.<br>
<br>
At any point in the process, I think it should be possible to produce a<br>
text file showing what is happening inside, in the actual user code that<br>
defines and animates the character.<br>
I haven't discussed this detail specifically in the working group but, for<br>
example, that is why we are not moving forward now with the existing<br>
'diverse models' HAnim change.<br>
We only had one X3D player that demonstrated the very important concept<br>
and no running prototypes. Some interest, but perhaps more interest in just<br>
sticking to the simplist way of just drawing everything directly in<br>
skeleton space instead of providing a systematic way to adjust things into<br>
skeleton space.<br>
<br>
Historically, this is similar to the step between hanim level1 where<br>
geometry is part of a segment and the level2 deformable skin where the<br>
'skin' is part of the humanoid with movement controlled by joint bindings.<br>
This step was practically impossible to prototype (see boxman script and<br>
bsC protos). It took an interval to get this best practice, along with the<br>
best practice displacer methods, of skin animation running in more than one<br>
browser. Yet today deformable skin is supported widely.<br>
<br>
<br>
because we realized some problems in wrl files.<br>

<br>
Maybe we can help. I can't think of a better forum to deal with wrl, x3d<br>
or general humanoid animation probems than our consortuium so please bring<br>
these problems forward.<br>
<br>
<br>
All the characters can be animated using BVH motion capture files in our<br>

<br>
Of course the goal is that we can define a system that can be used in<br>
every X3D tool. I think understanding of bvh format and best practice<br>
conversion to native X3D data types is important because it provides an<br>
interface with consumer devices that are being widely used. We recieved<br>
this link from an early contributor to h-anim<br>
</div></div><a href="http://cg.cis.upenn.edu/hms/**research/ADAPT/" target="_blank">http://cg.cis.upenn.edu/hms/**<u></u>research/ADAPT/</a><<a href="http://cg.cis.upenn.edu/hms/research/ADAPT/" target="_blank">http://cg.cis.<u></u>upenn.edu/hms/research/ADAPT/</a>><div>
<div class="h5"><br>
as another example. I hope you can meet with Norm at the show.<br>
<br>
To me it is most important that there is not a rush to define a standard<br>
but we search for the true best practices by testing several working<br>
solutions.<br>
<br>
<br>
All the animaiton sequences can be stored as an animation file<br>
<blockquote style="margin:0px 0px 0px 0.8ex;padding-left:1ex;border-left-color:rgb(204,204,204);border-left-width:1px;border-left-style:solid" class="gmail_quote">
<br>
</blockquote>
<br>
That goes right along with existing X3D HAnim practice. Either generate<br>
the data using scripts or interpolators and/or import data as a string or a<br>
file.<br>
<br>
I think another very important part of the motion proposal is the detail<br>
that the proposal introduces a change from 'realtime' to a fixed or<br>
variable author specified frames per second mode (fps).<br>
I think this is a way to synchronize the X3D player to some sort of<br>
capture or rendering device that works at fixed or known frame intervals,<br>
such as 'video' capture/playback.<br>
As usual, with X3D there are several ways to get this done and please keep<br>
in mind that we must search for a general solution to this method of<br>
animation capture/playback in X3D.<br>
<br>
I am also hoping you can briefly overview some of the current work of<br>
evaluation and validation of the existing HAnim model by showing the three<br>
specification examples we have been working on.<br>
<br>
Have fun in California.<br>
Thank You and Best Regards,<br>
Joe<br>

Based on last night's work, am also thinking that there are a few broad<br>
categories of animation:<br>
- composable behaviors that animate the body itself (Walk, WaveLeftHand,<br>
etc.) i.e. your demonstrated set of blendable behaviors<br>
- animations that move the body from place to place<br>
(WalkDownTwelfthStreet, WalkInCircle, TangoMotionCapture)<br>
- sequencers (WalkDownTwelfthStreet, TurnAround, Wait 10s, SitDown at bus<br>
stop, Wait for bus, StandUp)<br>
<br>
Any other categories or use cases?<br>
<br>
Myeong Won Lee, the most helpful things we might get from you (and<br>
others)<br>
would be example X3D scenes from your work that we might test and try<br>
out.<br>
<br>
all the best, Don<br>
