<p class="MsoNormal">The joint center values come from JinLOA(1-4) JSON files found here:<o:p></o:p></p>
<p class="MsoNormal"><a href="https://www.web3d.org/x3d/content/examples/HumanoidAnimation/">https://www.web3d.org/x3d/content/examples/HumanoidAnimation/</a><o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The “humanoid_root” joints are there. However, the bone wireframes displayed in Maya are based on the rotation pivot (aka HAnimJoint ‘center’ field).<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I’m guessing that you might be expecting bone wireframe to start it’s render at the grid origin? IDK… we can discuss it at the next HAnim group meeting to determine if I have it wrong.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Could they be exported as glTF? Probably, but it’ll be a while before I get around to exporting to that format.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">10-ish years ago, I tried to write an X3D/glTF exporter (that I called BaconXjF) completely in MEL to support export from Maya LT.<o:p></o:p></p>
<p class="MsoNormal"><a href="https://github.com/flickertail/bcn">https://github.com/flickertail/bcn</a><o:p></o:p></p>

<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Back then though, I didn’t’ have the freedom at work to develop an exporter the way I do now.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I don’t really remember anything at all about how the glTF format works. But I suppose it would be easier in Python.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I’m willing to collaborate with another programmer to implement a glTF exporter for RawKee. Or collaborate on a funding proposal to hire a programmer.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">But I’m largely working on RawKee in my free time after work, so I don’t have any spare time in the foreseeable future for that.<o:p></o:p></p>
