Thanks for the replies!
I found a bug in my code ...
Code:
void AnimatedModel::update()
{
for(int i = 0; i<m_bones.size();i++)
{
if(!_firstUpdate){
pBoneUpdate.at(i)->getStackedTransforms().pop_back();
}
if(!m_bones.at(i)->getName().compare("Waist")){
pBoneUpdate.at(i)->getStackedTransforms().push_back(new
osgAnimation::StackedTranslateElement(
"trans",modelTranslate));
}
pBoneUpdate.at(i)->getStackedTransforms().push_back(new
osgAnimation::StackedQuaternionElement(
"rotate",boneMatrices[i]->getMatrix().getRotate()));
debugAxesMatrices.at(i)->setMatrix(m_bones.at(i)->getMatrixInSkeletonSpace());
}
_firstUpdate = false;
}
Not all pBoneUpdate.at (i) -> getStackedTransforms have the same size ... must
delete the former because otherwise the transformations add up.
On the other hand I still missing something, movements of both arms are
reversed each other... What about this part of the code?
Code:
//c# code
Vector3 s;
Quaternion r;
Vector3 t;
if (!worldTransform.Decompose(out s, out r, out t))
return;
var currentPos = positionResolver(currentJointID);
var nextPos = positionResolver(nextJointID);
var shoulderToElbowDir = Vector3.Normalize(nextPos - currentPos);
var angle = (float)Math.Acos(Vector3.Dot(Vector3.Right, shoulderToElbowDir));
var axis = Vector3.Normalize(Vector3.Cross(Vector3.Right, shoulderToElbowDir));
worldTransform = Matrix.CreateScale(s) * Matrix.CreateFromAxisAngle(axis,
angle) * Matrix.CreateTranslation(t);
worldBindPoseCopy[bone] = worldTransform;
outputSkin[bone] = inverseBindPose[bone] * worldBindPoseCopy[bone];
I tried to multiply inverseBindPose by my matrix, but I deform the whole model.
I have another question ... if I have a model with bones Orieta differently,
this does not serve me, right? (the same code for diferent oriented bones
models).
Thank you!
Cheers,
Aitor
