Hello away3d team,
I dont know where I should post this so I posted it in the user’s discission and here. Anyway here’s my problem. Im trying to animate my md5 mesh manually, as my starting point I want to copy the SkeletonJoint’s orientation and translation to JointPose, but I came accross the issue where I could’nt find anything useful from SkeletonJoints properties. So my initial thought is that SkeletonJoints stored the orientation and translation in the inverseBindPose property, but when I tried to decompose it my model got screwed. Im not very good in Math and English so I think it’s better if i show off my code 
.
private function onAssetComplete(event:AssetEvent):void
{
if (event.asset.assetType == AssetType.ANIMATION_SET)
{
animationSet = event.asset as SkeletonAnimationSet;
//build the animator
animator = new SkeletonAnimator(animationSet, skeleton);
//build the skeletonPose for custom animation
skeletonPose = new SkeletonPose();
//create a jointPose for each joint ( clone :D );
for(var i:int = 0; i < skeleton.joints.length; i++)
{
var jointPose:JointPose = new JointPose();
jointPose.name = skeleton.joints[i].name;
var matrix3D:Matrix3D = new Matrix3D();
matrix3D.copyRawDataFrom(skeleton.joints[i].inverseBindPose);
matrix3D.invert();
var decomposedMatrix:Vector.<Vector3D> = matrix3D.decompose(Orientation3D.QUATERNION);
jointPose.translation.copyFrom(decomposedMatrix[0]);
jointPose.orientation.fromMatrix(matrix3D);
skeletonPose.jointPoses.push(jointPose);
}
//create a new clip and add it to animationSet
var skeletonClip:SkeletonClipNode = new SkeletonClipNode();
skeletonClip.stitchFinalFrame = true;
//add 2 frames since it will throw an error only 1 frame is added
skeletonClip.addFrame(skeletonPose, 1000);
skeletonClip.addFrame(skeletonPose, 1000);
skeletonClip.name = "myAnim";
//finally add the clip to the animationSet :)
animationSet.addAnimation(skeletonClip);
mesh.animator = animator;
animator.play("myAnim");
}
}
I’ve searched google and other posts and I always find people struggling on this king of issue but nothing works for them. Hope that you will kindly answer my question. Thanks :D
