Hi, I need the help of a mathematician!! As I explained above the skeleton and the animation are loaded by BVH plugin ... can be seen the skeleton in image ...
[Image: http://img193.imageshack.us/img193/4586/imageoir.jpg ] I dont get descrived appropriate rotation matrix to send to the shader... Code: for(int i = 1; i-animList[0]->getChannels().size();i++) { osg::Node* boneNode = checkName(skelroot.get()->asGroup(),animList[0]->getChannels()[i]->getTargetName()); osgAnimation::Bone* bone = dynamic_cast-osgAnimation::Bone*-(boneNode); osgAnimation::Bone* boneParent = dynamic_cast-osgAnimation::Bone*>(bone->getParent(0)); if(frames == 2) initBoneMatrices[i-1] = bone->getMatrixInSkeletonSpace(); boneMatrices[i-1].makeIdentity(); osg::Matrix transMatrix = bone->getMatrixInSkeletonSpace() * osg::Matrix::inverse(initBoneMatrices[i-1]); osg::Quat lastRot = tempBoneMatrices[i-1].getRotate(); osg::Quat rot = bone->getMatrixInSkeletonSpace().getRotate(); osg::Quat rotWorld = rot * lastRot.inverse(); osg::Matrix rotMatrix = bone->getMatrixInSkeletonSpace() * osg::Matrix::inverse(tempBoneMatrices[i-1]); boneMatrices[i-1].preMultRotate(rotMatrix.getRotate()); boneMatrices[i-1].preMultTranslate(transMatrix.getTrans()); tempBoneMatrices[i-1] = bone->getMatrixInSkeletonSpace(); } Thank you!
