Demo not working? geo.applyMatrix4 is not a function #27

Open ccj242 opened 2 years ago

ccj242 commented 2 years ago

Hi! This looks like an amazing library and it's definitely possible I'm missing something here, but I can't get the demo working -- I get "geo.applyMatrix4 is not a function" error in the console with all browsers. Thanks!

ccj242 commented 2 years ago

Anyone have ideas on this? I can't even get the online demo working: https://jsantell.github.io/THREE.IK/

Thanks in advance for any advice!

@ccj242 Yeah I'm also seeing some issues with the demos. I'm guessing this library needs to be updated for the latest version of THREE.js

I hope it's a quick fix that @jsantell can take care of as I'd like to use this for my project,

ccj242 commented 2 years ago

@jamesrez - have you had any luck downgrading three.js to previous versions? I'm trying that now and no luck so far, but I'll let you know if I get anywhere. Thanks for confirming! I thought it was just me and I was going a bit mad!

@ccj242 I've been trying to get it working in the latest version and it's certainly broken right now.

After debugging some of the code I was able to get it kind of working with my model, but all of the bones were super stretched out and twisty no matter how much I played around with the values.

I need IK though, so I'm still looking for a fix.

So per this PR I was able to get the examples working by installing version 127 of three.js using install three@0.127.0 --save Hopefully this helps!

The demo linked from the README (https://jsantell.github.io/THREE.IK/) appears to be out of date and still have this issue.

I'm looking for a three.js IK library, and this one seemed good, but I did assume the last modified date being years ago would be an issue. I really hope there are plans to fix it.
