[Maya-Python] Re: aniMeta - simple rigging tools
Hi Marcus, saw you ragdoll stuff, pure awesomeness! Regarding your questions, HumanIK is IMHO only good for retargeting animation(mocap) data in Maya. It is integrated in aniMeta by creating a hik character along with the actual rig and than there is an extra group with a pairBlend on each relevant control so one can dial in or out the hik effect ( "mocap" attribute on each control ). This allows one to animate/tweak the mocap data, ie for foot locking. I have not implemented a baking step, yet, I guess that depends if it gets becomes a priority for some reason, so far I had exported the animation then directly to game engines, mostly UE. Your question regarding a comparison to other solutions is very interesting, as it touches the design choices made. There are already a few options for auto-rigging out there, why bother putting out another one? First, the key idea behind aniMeta is simplicity with having novice users in mind. In my experience it can be already a challenge for users to install a script/plug-in. My idea was to have everything needed in a compact format with no dependencies/build/platform/installation issues, that is way I made the choice that aniMeta needs to be a single text file that can be started from the plug-in manager. Second, regarding features, the biped template would probably be considered basic when compared to other options out there, especially mGear. but that also makes it fast and has only what I consider the most important features to get some decent game animation loops. It is also vanilla Maya, so a rig created with aniMeta can be opened on another machine that does not have the plug-in installed. That is also a difference to mGear, which uses custom nodes. So IMHO mGear is definitely the choice if you need to customize stuff and want advanced features, aniMeta is more of a light-weight but fast solution, but offers some neat features that maya make it interesting for character TDs. For example. there is a tool to export/import hierarchies(json), there is skinning IO(json) and a procedural build system, which I used last year to build a couple of mGear characters with. So it complements Maya where I see some Maya`s rigging features lack and aniMeta can easily combined with other rigging tools and solutions out there. Some students told me that the smooth weights tool alone already makes it worth having around. I know there isn`t any info about usage of aniMeta yet. But I am in the process of putting info stuff together so people can get a more specific idea of what it is and how to use it. But so far thanks for your interest! : ) Marcus Ottosson schrieb am Dienstag, 11.

[Maya-Python] aniMeta - simple rigging tools
Howdy, I created this auto-riggerfor my students that has features that I find vanilla maya lacks and published it on github as open-source. It is easy to install, it is just one py file that can be started via the plug-in manager. I thought it may be interesting to some of you, so here you go: https://github.com/janberger/aniMeta Here are some features: - Biped template ( Unity and Unreal compatible ) - HumanIK inegration - Skinning IO - Very nice Smooth Weights Tool ; ) - Picker UI - Rig, Pose, Animation IO - Transform tools ( mirroring, matching et al ) Overall the rigging features may seem limited for the Biped, because they are ; ) but keep in mind it is for students, especially game design students. For more advanced stuff. there is a procedural build system for a data-cantric workflow integrated, but I guess I need to write some documentation before anybody but me can use it.

Re: [Maya-Python] Re: environment for API calls ?
A short answer would be yes, you can do it and it gives a lt of possibilities, but if you are talking abou a script in the context of a bunch of commands being executed one after another, you should realize that with calling the API you may run into undo/redo issues. I have done it in production but only to do really opportunistic stuff, like copying mesh data around without creating tweaks etc. and where creating a scripted or not plug-in would have caused too much overhead. But I really like this combo of API and Python and can only encouraged to go down the path of Dark Magic Power Moves as I call it ; ) At 18:56 02.09.2011, you wrote: More precisely, if there is a boundary between python scripting and API calls, how is it formalized ?

Re: [Maya-Python] Re: Adding up child rotations
The example in the blog just spits out what has
been put into the TransformationMatrix.
The question is whether when you add a rotation
this will be kept track of as well, right?
If I were you I would take the code from the blog
and add some rotation either with rotateBy
or addRotation and then see what it spits out.
Sorry I can not give you direct answers and/or write code ...

My current mel script that I'd like to turn into a scripted plugin:

By classic way do you mean using the MMatrix class?
Because 'AK Eric' says in the above mentioned description that the
MTransformationMatrix [class] will keep track of rotations past 360
degrees rotation order of the node, while MMatrix objects will not.
It makes sense: A matrix itself stores orientations as vectors, which
have no concept how how far they’ve been ‘rotated’, so the MMatrix
object doesn’t track this data. But behind the scenes, the
MTransformationMatrix does track this info...
http://www.akeric.com/blog/?p=1067
The whole point of the plugin I want to create is to add up how many
times the source nodes have spun and incrementaly add the rotations
together and output it on to one node. It sounds like
MTransformationMatrix::rotateBy would allow me to do this?

Internally the 4x4 matrix is just a bunch of vectors, that dont

So I am not sure if the classic way will get you what you are looking for.

What would be the scripted plugin code to do 'relative' additive
rotations on one transform from the rotation values of nodes in a

I'd like to use this class that supports rotations past 360 degrees

From the docs: Utility class for working with pointers and references. Utility class for working with pointers to basic types such as int, float and arrays of these types.
