Oh nice vid thanks for sharing So I usually blend my successive animations CPU side before passing in my uniforms so I end up using the same number of uniforms no matter what.

Oh awesome and thanks a lot for the link. I'll definitely need to spend some more time playing with and learning from all of the existing solutions

Yeah one thing that I'm really hoping to see in the graphics community is a nice selection of standalone pieces that you can combine into your own rendering pipeline.

And thank you for the feedback! So, it turns out that this demo doesn't use Three.js, but the idea is that, if you wanted, you totally could :) And I'm a Blender noob as well, this tutorial series on character modeling, texturing,

Oh interesting: So the short answer is - not in the demo, but yes in your own code --- The demo's model rendering is powered by load-collada-dae ( https://github.com/chinedufn/load-collada-dae ) which right now ha

Great points, along with greggman's http://webglfundamentals.org I'd also recommend http://http://learningwebgl.com/blog/?page_id=1217 --- So I'm fond of the idea of being able to q

Hey thanks for pointing this out since I admittedly hadn't even really considered using anything other than JSON here. It turns out that the files are roughly the same size since the parser just shuffles the data around to make it easi

Super interesting perspective here :) Question - in this no-customer scenario what's the downside of trying to solicit feedback from others while you go along?

Great point about the signal to noise ratio. One interesting thing there is how the ratios differ between a mostly emotional experience (a new social platform for example) vs.. say.. a product that helps the user make more money (most B2B).

Sure thing!

by chinedufn 10y ago
Yup yup, both non-normalized dual and regular quaternions will give you artifacts similar to blended matrices.

You're too kind! Thanks!

by chinedufn 10y ago
uh oh :( Well if it still doesn't work, feel totally free to try it locally: ``` git clone https://github.com/chinedufn/collada-dae-parser cd collada-dae-parser npm install npm run demo ```

by chinedufn 10y ago
Ah good question. So I was using linear blend skinning and had those horrid artifacts. Google.com told me that dual quaternion skinning was the solution, so more or less blindly went with that. santaclaus mentioned OCR in another comment, s

Thanks! So admittedly I only heard of DLB a few weeks ago, and OCR skinning 10 seconds ago :) But this looks pretty damn cool. Thank you so much for the link, I'm definitely going to read this paper and consider it for a standalone ske

Ah good idea linking to an image. Great illustration of the problem :)

So the problem with blending matrices is that you are not guaranteed to get a rigid transform (you might introduce scaling, for example). You are also not guaranteed to get the shortest path between your start and end matrices. So you'
