<div dir="ltr">I did some exploring around X3D-Edit, looks like Pirouette.x3d (from .bvh importer in X3D-Edit) is loading into view3dscene, FreeWRL and X_ITE (on the website). I don't know what the original animation looks like, but I can't distinguish the humanoid in any of the browsers from opening scene, but from looking at the X_ITE version, the camera looks way off. Once the camera is positioned properly, the model looks okay. I'm not sure what can be done about this? Other MotionAnimation files converted from .bvh look okay camera-wise.<div><br></div><div>Would it be possible to convert an HAnim LOA4 file from a LOA4 .bvh file?<br><div><br></div><div><div>Pirouette is also here: <a href="https://threejs.org/examples/#webgl_loader_bvh">https://threejs.org/examples/#webgl_loader_bvh</a></div><div><br></div><div>I looked into converting an HAnim .x3d into something like COLLADA (.dae), with X3D-Edit which it seems is used to transfer HAnim into Blender (and glTF?). My guess is most people use MakeHuman, export to COLLADA, then import into Blender. Or convert X3D to COLLADA.</div><div><br></div><div>What it the best path to modify the translation of a <br>X3D, VRML or JSON humanoid from one location to another using scripting or other? I have to find the average of the feet, and translate the humanoid (all centers of joints) by the amount of the average position from 0,0,0, which centers feet around the origin. I do not have a currently approach to do this in JavaScript apparently, and Blender/Python doesn't work because I can't load an Armature from HAnim X3D XML.</div><div><br></div><div>I'll start working on the JavaScript again tomorrow.<br><div><br></div><div>Thanks!</div></div></div></div><div><br></div><div>John</div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Thu, May 4, 2023 at 10:40 PM John Carlson <<a href="mailto:yottzumm@gmail.com">yottzumm@gmail.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr">Okay!
