Hi,
I've noticed that when holding information from animation channels, only gives
me the bone local position information. "rotateX", "rotateY" and "rotateZ"
values are always 0.
Code as I do:
Code:
osg::ref_ptr<osgAnimation::Bone> actualBone =
_AnimationManager->getSkeletonBone(actualBoneName);
while(actualBone->getParents().size()>0)
{
float rotateX, rotateY, rotateZ;
osg::Vec3 pos;
for(int j=0;j\channelList.size();j++)
{
osgAnimation::Channel* channel = channelList[j];
if(!channel->getTargetName().compare(actualBoneName))
{
if(!channel->getName().compare("translate"))
{
osg::ref_ptr\osgAnimation::Vec3Target> posTarget =
dynamic_cast\osgAnimation::Vec3Target*>(channel->getTarget());
pos = posTarget->getValue();
}
else if(!channel->getName().compare("rotateX")){
osg::ref_ptr\osgAnimation::FloatTarget> xTarget =
dynamic_cast\osgAnimation::FloatTarget*>(channel->getTarget());
rotateX = xTarget->getValue();
}
else if(!channel->getName().compare("rotateY")){
osg::ref_ptr\osgAnimation::FloatTarget> yTarget =
dynamic_cast\osgAnimation::FloatTarget*>(channel->getTarget());
rotateY = yTarget->getValue();
}
else if(!channel->getName().compare("rotateZ")){
osg::ref_ptr\osgAnimation::FloatTarget> zTarget =
dynamic_cast\osgAnimation::FloatTarget*>(channel->getTarget());
rotateZ = zTarget->getValue();
break;
}
}
}
osg::Quat rot(osg::DegreesToRadians(rotateZ),osg::Vec3(0,0,1),
osg::DegreesToRadians(rotateY),osg::Vec3(0,1,0),
osg::DegreesToRadians(rotateX),osg::Vec3(1,0,0));
osg::Matrix
mat(osg::Matrix::rotate(rot));
mat.setTrans(pos);
desiredMatrix.preMult(mat);
actualBoneName = actualBone->getParent(0)->getName();
actualBone = _AnimationManager->getSkeletonBone(actualBoneName);
if(!actualBone.valid())
break;
}
Without the information of local rotation of each bones I can't calculate its
transformation matrix in skeletal space!
I'm doing something wrong?!
Thank you!
Cheers,
Aitor
