🧵 Blender Bone Envelopes
Anonymous at Sun, 19 Feb 2023 16:02:40 UTC No. 937495
On the right is what you get by default in Blender 3.6 It's unuseable because of the pinching on the interior side.
On the left is what I've got after a day of hacking at the code. If anybody's interested, I've got more examples and code to share.
Anonymous at Sun, 19 Feb 2023 17:05:54 UTC No. 937503
Same as before but with a 90 degrees bend. Top left is Blender 3.6, bottom right is my patch.
If you're wondering why bone envelopes instead of vertex groups, weights, hooks, drivers, whatever voodoo the latest tutorial guy suggests, it 's because they're easy to use.

Hi to you too. Yes. I've seen that gif before. You could do that but it's a lot of work. You can spend your time doing that.
The examples I've posted here are just bone envelopes with no special weight painting or topology.

GIT? I don't use Microsoft products such as GIT. I'll make a patch for the solution I've found and I'll post a link to it later.
In the meantime if you want to give it a shot yourself, open "armature.c" and locate the function "distfactor_to_bone" in it.
The bad pinching is caused by the fact that the caps of the envelope have the same influence as the cylindrical part, so when the caps and the cylindrical parts overlap, the caps distort some areas that are supposed to remain straight.

I just wanted to show that you can get even better results by giving the bones a little bit of "pre-bend". No vertex weights to adjust. And a wireframe view to show what happens inside.

To share the idea. To tell people that the youtube tutorial guy who tells you to use drivers with python code, auxiliary bones, hand painted weights and custom topologies is insane.
That all of the above are just baroque workarounds for crusty old, bad code which is in the C codebase and it's burden-shifting from sloppy programming directly to a huge waste of time for the users.

If you got bone envelopes to work properly that's fine, post the code.
But basically no one is using them everybody is using vertex group weights.
Now it would be awesome if there was a working, less labor intensive alternative and I suspect you need to add even more patches to bone envelopes to make that happen.
Anonymous at Mon, 20 Feb 2023 03:02:55 UTC No. 937566
I'm curious, what's other software like? You just auto-rig a model and it gives you perfect elbow deformation out of the box? No need to touch up the weights or make corrective shape keys?
Somehow I doubt that.

To my knowledge the function "distfactor_to_bone" has never ever been touched since Blender was released as GPL.
Maybe people tried it over time, correctly decided that it didn't work and moved to vertex weights even in situations where bone envelopes would have sufficed.

Since you've mentioned an elbow, I've made an abstract one real quick and bent it with just bone envelopes. It's not perfect but it requires practically no work at all.
>>937569
I'll post it soon but it's essentially one line. As I've explained above it just sets the cylindrical part of the bone envelope to take precedence over the caps. I'm sure there are way better solutions people smarter than me can come up with.

Most of it is about a replacement for the metaballs system but if you search for "armature.c" inside that file, you'll see it.

uh, what are shape keys?
skeleton subspace deformation is very efficient to compute, but suffers from pinching and collapse at extreme angles. this is a very well known issue that shape keys completely solve.
you can play around with bone weights all day and never eliminate this problem because it is inherent to the math.

you've shown nothing of the sort. it absolutely is. i know exactly what blender is doing under the hood because i exported blender models for use in research simulations, and i had to reproduce all the math that blender runs to make models work outside of blender.

Let me give you some more details.
As it is, Blender assigns vertex weights from envelopes via a somewhat incorrect capsule distance field. The capsule field is continuous.
A continuous surface warped by a continuous field gives a continuous result. That's somewhat correct for the outside of the bend but it's not for the inside.
What you want instead is a field that is continuous when there is no bend, remains continuous on the outside of the bend but becomes discontinuous on the inside.
Any field that satisfies these constraints will work better than the linear field that's currently implemented.
I've chosen the possibly simplest solution for this demonstration, but if you understand math, you can go at it and find better solutions.
Just don't propagate myths that a particular problem is unsolvable just because Blender mathematicians say it isn't.

you are missing the point. it doesn't matter how you assign weights, if you have two subspaces controlling the same points with weighted averages, then you can always cause pinching and collapse by choosing the right (wrong) transformations for the subspaces.
you can come up with the most clever way to assign weights, and you still have this problem.
the whole point of shape keys is to address this very problem.
when your geometry looks bad after posing, you just fix the geometry and save the new shape key. it's the easiest, best way to deal with the issue.

it's not. it's what everyone uses. once vertex data is generated, deformation and animation is literally weighted average upon weighted average. it's the only way to do it efficiently.

and shape keys could make it work.
for example, you forearm can rotate 180' without collapsing to a point. if you want to properly model a forearm, then you need both skeletal subspace deformation and shape key deformation.

The topology of the mesh is unoptimized. It's just whatever comes out of the metaball/SDF marching cubes process.
Not vertex weight/painting. No Shape keys. No Drivers. Just bone envelopes.
Because it doesn't rely on hand painted vertex weights, the mesh can even be replaced entirely after posing. Bones can be re-positioned and parameters changed on the fly with no extra work required.
Again, it's not perfect but it's a lot better than whatever comes with Blender by default.
And despite some Blender geniuses claims that this is mathematically impossible, I know that it could be made even better.
If you want to see some specific scenario, ask nicely and I may make it happen.
The link to the code I've already posted 3 times. Just scroll up a little bit.
Anonymous at Sun, 26 Feb 2023 05:16:34 UTC No. 938312
One idea I'm considering is to use negative vertex weights.
The way I've set it up right now, the interior of the bends are as sharp as they can be but maybe sometimes it would be nice if they would bulge out slightly.
In some complex rigs (such as the one in pic related) you can see a bone going backwards after the elbow joint. I suspect the role of that auxiliary bone is to emulate a negative vertex weight somewhere.
I don't if and ever I'm going to work on this idea, but if you're able to code, you're welcome to try it out before I do.

the whole point of bone envelopes is to produce vertex weights automatically.
instead it seems you are using metaballs to compute the vertex weights. is this correct?

No. I can use any mesh. I've used metaballs (SDFs actually) just to draft the example meshes that I've posted. I'll post an example of bending a subdivision mesh eventually, but it makes no difference.
I'm also working on something else entirely different where I do generate automatic vertex weights from SDF information, but that's another project.

However, the way bone envelopes work in Blender by default is by computing a distance field from the bone.
I'm using the same method but with a slightly different formula.
Anonymous at Sun, 26 Feb 2023 05:44:13 UTC No. 938316
As I've already said at the beginning of the thread, Blender uses the function "distfactor_to_bone", which is a sense is an SDF, except it's reversed and clamped.
I've modified that function. I've also removed the code related to the bone head/tail size because for reasons long to explain, it's broken, confusing and does nothing anyway.
Anonymous at Sun, 26 Feb 2023 05:49:57 UTC No. 938317
For more details you're going to have to look at the code because I can't explain it any better than I've already have in words.
I'm also not trying to convince anybody and sure, shape keys solve everything... at a big price.
I also think that comparing bone envelopes with a manual technique such as shape keys is a little bit dishonest on your part.
Anonymous at Sun, 26 Feb 2023 05:53:55 UTC No. 938318

so you are computing vertex weights and using the standard SSD+SKD to compute mesh deformation.
claiming that your method solves the collapse/pinching issue of SSD without SKD is the dishonest part, because it can't.

Yes. Exactly. In fact the bake bone envelopes to vertex weights option still works in my patched version of Blender. Multiplying with hand painted vertex weights also still works. It just make it optional. And in fact I have some vague memory of some (obscure, almost certainly closed source) 3D modeling thing that did something similar to "my technique".
I say that in quotes because at its core it's so simple I'm almost certain I've actually "independently re-discovered" it.

You may notice that I've removed the head/tail ball size parameters, so now the visualization is a combination of stick mode and envelope mode.
Because of the way vertex weights work (which I haven't changed) the head/tail ball size do essentially nothing because the code is somewhat bugged and they just shift the linear field outwards, but since the contributions are normalized at the end end of the process, then... And it's two less parameters per bone to worry about.

The thing I like the most is that I can easily shift the bones positions without have to re-calculate anything. It's actually fun to use and that's the thing I care about above anything else.

the simplest way (and you won't like this) is to
1) put it into the pose you want (like the hand touching the shoulder, which you've done)
2) manually tweak the mesh to look good in this pose (fix self intersections, make muscles bulge, etc)
3) create a new shape key
4) add a driver based on the transformation parameters of the bones (i.e. the angle between the upper and lower arm bones) that controls the interpolation between the two shape keys
for something as complex as a human, you may need to break the body up into a bunch of different meshes (arms, torso, legs, etc) to make this a robust solution, since a shape key is for the entire mesh, not just a subset of vertices (unless that's been recently changed).
all of this is necessary because SSD+SKD isn't a physical model, but it is extremely easy to compute. of course, you could use a more complicated physical model to compute the interaction of geometry, but this is computationally expensive and takes away your ability to tweak things since now everything is contingent on a physics equation and not artistic license.

I've re-positioned the elbow joint, fixed some bone roll issues and added some color to help show what's going on with the mesh.
No Corrective Smooth, no other filters, no manual tweaking of vertices. Just bone envelopes. For what it is I'm very happy with it.

You do need a patched version of Blender (as I've tried to explain ITT) or some other software that actually works or some very carefully hand painted vertex weights to do this, but it's possible.

that image shows clearly where the method fails, do you see that large flat spot on the extending side? That's a single edge/face which will produce some awful texture stretching. You can migitate this with subdivisions, but for realtime cases this is not an option.

You have to consider that I'm working within the limitations of the existing armature system. You're welcome to do better or ignore all of this if you don't like it.

not that guy but for low poly models you'd want to preserve the volume as much as possible.

how do you install this .diff patch?

Part of the reason I'm doing this is because I've always liked the look of those old PSX models that were made of discrete pieces. They had visible breaks at the joints but not volume loss or pinching issues.

You have to get the Blender 2.76 source, re-build it, apply the patch and then re-build again.
It's hard to do in general and on Windows I've been told it's hell on earth.
Unfortunately if you have to ask, it means you'll have to wait until somebody to publishes a patched binary.
The Blender people are unlikely to ever incorporate any of this because it doesn't affect their proven "import from Maya and claim it was made in Blender" pipeline, so...

that's fine. i can still view the code in vscode and get a sense of the underlying logic, so there's merit behind having it. it's a pretty cool implementation all in all, and depending on how efficient it is compared to using weight painting and topology techniques, i could see myself wanting to repurpose it in a game engine.

That's the best you can do in my opinion. Try to understand the general idea and then do your own implementation, which is very simple anyway. Also consider >>942102 because I managed to get the same results as in here but using standard weight groups.

This is just how weight paints work. The bone influence is dependent on the weights.
>is insane
>a lot of manual work
because you won't learn to do it properly. You think you're going to automate their methods without understanding them.

>You could do that but it's a lot of work.
lmao why
why is the quick and easy way the hard way, while mangling the blender source code to get it to do it a really specific and limited way the easy way, in your opinion?

Migrate to >>942102 because in between starting this thread and now I believe I've found a batter way to do the same thing, which is explained there. That's still my thread, I just don't want some rogue janny to ban me again for having two similar threads.
A short answer to your question is that if you like do hand paint your rigs, then none of the changes I'm presenting here or on the other thread affect you in any way.
