<div dir="ltr"><div>John,</div><div dir="auto">> 1. Who is going to pay for AI training?</div><div>- great question.</div><div>There are little computers Nvidia Jetson Orin Nano Developer (check Amazon) for 400 to 1500 $</div><div>- they are loaded with Nvidia's AI stack for peripheral AI, linux OS, and various 3rd party have 'foundation models' for various things</div><div>- One option for funding: there could be a little club, where those who want to provide the tool to their users, would chip in (note 1)</div><div>- the data sets - <a href="http://web3d.org">web3d.org</a> has lots of data sets / x3d example scenes, and the images for them can be generated with an x3d-browser (note 2)</div><div dir="auto">> 2. Is there a foundation model we can use?</div><div>- great question. </div><div>- presumably the Nvidia stack comes with some basics, and 3rd parties might have some refined models</div><div>- AlphaFold by DeepMind: AI used to solve protein folding, used the 2 step confirmation method, where the AI would give a best guess, then a chemical bond checking algorithm would confirm or reject its logic and feed that back for refining the AI training, (I read somewhere, so it must be possible to do that.)</div><div><br></div><div>Note 1: there could also be a shared 'resource pull tool' for club members, and public downloaders would see a screen with </div><div>tool-or-resource-name [Install / Uninstall / Update / Discontinued ] button for each tool or resource. So someone downloading freewrl, would get the pull tool that allows pulling sunrise, x3dom server, castle model viewer, x3d-edit, ....., and the Update button would be lit when there's a new version.</div><div>Note 2: complex shapes like HAnimHumanoid would be easier to train AI for if instead of training against a mesh, it was training against simplified scalar parameters, like MakeHuman / MPFB extension for Blender. There could be an abstract x3d type HanimGenerator, and a concrete type HAnimHumanoidGenerated that derives from it and HAnimHumanoid, and on rendering, it generates the skin Shape and textures, and coveroids / clothing based on parameters. Since AI trains on the scenefile --not the runtime scenegraph-- it would only need to learn a few dozen slidebar parameters and control them to generate a humanoid that looks like the training image. This would allow x3d authoring tools to tinker with the humanoid looks with slidebars, and allow x3d-browser events to change the look of the Humanoid on-the-fly / at runtime.</div><div>-Doug</div></div><br><div class="gmail_quote gmail_quote_container"><div dir="ltr" class="gmail_attr">On Thu, Nov 13, 2025 at 3:43 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="auto">That sounds good, Doug.
