XNA Animation Component Library

Closed Feature: Add support for Acclaim ASF/AMC animation format [5810]

mnikonov — Thu, 16 May 2013 09:34:59 GMT

Here is some info on the format:
http://www.cs.wisc.edu/graphics/Courses/cs-838-1999/Jeff/ASF-AMC.html

There is a good library of animations in ASF/AMC at CMU:
http://mocap.cs.cmu.edu/

This format allows saving skeleton and animation in separate files. So you can have multiple AMC (animation) files for a single skeleton (ASF).

The format is fairly simple to parse.

Closed Issue: typo in source file name - ModeAnimationlInfo.cs [5893]

mnikonov — Thu, 16 May 2013 09:34:58 GMT

File should be renamed to ModelAnimationInfo.cs

Closed Issue: Make sure component works on FBX files [5899]

mnikonov — Thu, 16 May 2013 09:34:57 GMT

I tested the component with an FBX file and the animation was imported such that each joint had a separate AnimationContentDictionary.

I need to find out if this is the case for all FBX files, and if so, combine the animations in the processor.

Also, I need to make sure the component works on fbx files.

Closed Issue: Lets get rid of SkinTransforms [6000]

mnikonov — Thu, 16 May 2013 09:34:57 GMT

The SkinTransforms information in importer/processor is actually redundant.
And what's more important, it affects AnimationController's ability to animate FBX models.
The .X importer and AnimationController should be re-designed so that they do not require SkinTransforms, but instead allow animation of models loaded via standard XNA importers (.X and .FBX).

In XNA, the bind pose is stored as the transform matrix of each bone, so there is no need for separate skin transforms like in D3DX.

To transform vertices into bone space, multiply them by the absolute transform of the mesh, followed by the inverse of the absolute transform of the bone

See this post on skin weights and skin transforms:

David, what do you think of possibility of this modification?
Would you support it?

I can do this, but I need to coordinate this with you as it affects core classes.

Closed Feature: Try to make component work on default x importer [6417]

mnikonov — Thu, 16 May 2013 09:34:56 GMT

Now that the v 1.0 has been released, the default x importer should be more stable. This could be merged with the "lets get rid of skint ransforms" issue, but we should try to make the component work using the default importer.

I still want to keep the custom importer, since it gives a lot more flexibility, and fixes some issues (I.E., maya exporter exports skin weights with values over 1.00, and XNA importer throws an exception) that exporters might have.

Closed Issue: Test [7446]

Hello everyone, I just wanted to share some knowledges I've been gaining through the years that may be useful. I don't know if this will work for everyone but it seems to work fine at least for me. -Tips to Export models from 3Ds Max with Panda in order to use with XNA Animation Component Library: http://www.abstractfactory.com.ar/diegoCosta/images/XNA/XNA-ACL-Export1.jpg -Tips to get animations right in XNA if the model is fine but animations are not being played correctly http://www.abstractfactory.com.ar/diegoCosta/images/XNA/XNA-ACL-Import1.jpg I hope it helps! cheers, Synth (originally posted on Jun 5, 2011 at 4:45 AM)

New Post: integration with MonoGame

dolanmiu — Mon, 28 Jan 2013 04:18:22 GMT

I would like to know this too actually. I guess we can just try it and see what happens

Have you seen this alternative one:

http://xnanimation.codeplex.com/

It might be better? It has fewer downloads though.. and one of its key features include "easy to use"

not sure..

Edit: my bad, it seems that project is dead

hey look at this

New Post: Attach objects to a bone

middle — Sat, 12 Jan 2013 13:34:53 GMT

Hello everyone.I have exactly the same problem. For weeks I'm trying to figure out how to attach an object model of a bone. I found your example library today. Can I use this library to attach a model of a bone? I looked all threads and none contain an answer to this. Thank you very much for your example and made this wonderful project. good day ^

New Post: Working with animated models from FBX

stark7 — Fri, 11 Jan 2013 02:35:56 GMT

Thanks a lot for this code, I am in the process of trying it out with MonoGame - quick question though - I do not see a FBX - AnimationLibrary - does this mean that the regular Autodesx FBX Content Importer will work with all fbx and then choose Model - Animation LIbrary for the content processor and that will get me good to go?

stark7 — Fri, 11 Jan 2013 02:34:09 GMT

Hey I hope someone else responded to this since 2011 :) but the way you do it is that you get the Transform (which is a matrix) of the Bone you want to attach an object to and then set that transform to your other object - you will also need to apply an offset so you don't overlap with your model's mesh. I don't have example code of this yet.. working on it myself.
