Anim8or Meshes put through Their Paces With BVH

<< < (9/11) > >>

Hi ho, it's very interesting looking at how the bvh files make bits of the character moves - eg unexpected movements like head jerks because of inertia when the body changes direction in a dance move . Of course as expert anim8ors  we all would expect that :(

Francesco, it lookd like you are coming along in leaps and bounds and leaps and bounds and LEAPS and bounds :)

Unfortunately I can't help in the maths, as the modst I ever inderstood about scripts is how to turn the traffic lights off in Leslie's tutorials :(.

Uggh. Last time I did maths at uni I got 49 out of fifty for first semester and 2 out of fifty for second semester ( I went surfing :)  in second semester)

But I am eagerly awaiting your discoveries.

Thanks for all the hard work.

Francesco:
You're welcome Andrew, I hope to sort things out asap.

Crossing fingers ;)

Francesco:
I was definitely lost in a glass of water.

So far, the only problem about the code I pasted above is about the eulers to quaternion function, which exchanges roll with pitch or something like this - at least is seems to be so.

So, the basis pose seems to be worked out. I'm attaching a picture that shows the basic pose of a BVH file (I guess that this pose isn't OK for easy skinning). Adding the starting t-pose as you requested is not done yet, Andrew.

After having fixed the skeleton conversion, I realised that the motion angles cannot be fed to Anim8or in the raw way, because BVH and AN8 use different rotation orders.

Nonetheless, using the raw motion data I've made a simple render showing the hooker walk taken from Animazoo.com

As you can notice, most of the animation goes fine, but the lower section of both legs bends to weird angles (more the motion, more the error when feeding erroneous rotation order).

So, this is what my converter can do so far. As soon as I sort out the rotation order conversion I will share the executable.

The video inside of the zip file is an XviD, fyi.

Enjoy!

headwax:
That's aabsolutely amazing Francesco !!!!!!!!!!!!



I think you have changed the face of anim8or!

Edit

I ran hooker walk through truspace then resaved it. Don't think it will make much difference. seems to have just changed the frame rate! Reason? Sometimes the bvh files act weird in parts regardless of the software. Truesoace tends to filter it somehow.

kreator:
Well what can I say ... This is just what Anim8or and Animators really need !!!!

I am extremely impressed Francesco!!  this addition like some of NickE`s scripts are opening more and more new doors for anim8or

I look forward to the finished result as I expect Andrew does as well!
