Hey everyone.
I have some previous posts on trying to get 2 hands to animate to sensor input.
I have a NodeVisitor class that goes through a model and adds a NodeCallback
class to each MatrixTransform node it finds. Then in that NodeCallback I do
some tests to see if it is a
MatrixTransform that I want to affect.
In the NodeVisitor class I attach some axes to the nodes I am looking to
affect. When runing
the axes move around according to my input but the model stays stationary. Am
I missing something on how this should be implemented?
NodeVisitor Class:
Code:
FingerTraverser::FingerTraverser(ErghisAPI::ErghisAPIController * a, int hand) :
NodeVisitor(TRAVERSE_ALL_CHILDREN), api(a), fc(new FingerCallback(a,hand))
{
}
FingerTraverser::~FingerTraverser()
{
void FingerTraverser::apply(MatrixTransform &node)
{
ref_ptr<MatrixTransform> joint = dynamic_cast<MatrixTransform*>(&node);
OSG_FATAL << "Joint lib name: " << joint ->libraryName() << "::" <<
joint ->className() << "Joint node name: " << joint ->getName() << std::endl;
if (joint)
{
joint->setUpdateCallback(fc);
joint->setDataVariance(Object::DYNAMIC);
joint->addChild(createAxis(5));
}
traverse(node);
}
The NodeCallback class:
Code:
FingerCallback::FingerCallback(ErghisAPIController *a, int h) : api(a), hand(h)
{
fingerTypes[L_IND] = fingers::finger::Index;
fingerTypes[R_IND] = fingers::finger::Index;
fingerTypes[L_MID] = fingers::finger::Middle;
fingerTypes[R_MID] = fingers::finger::Middle;
fingerTypes[L_RING] = fingers::finger::Ring;
fingerTypes[R_RING] = fingers::finger::Ring;
fingerTypes[L_PINK] = fingers::finger::Pinky;
fingerTypes[R_PINK] = fingers::finger::Pinky;
fingerTypes[L_THUMB] = fingers::finger::Thumb;
fingerTypes[R_THUMB] = fingers::finger::Thumb;
}
FingerCallback::~FingerCallback()
{
}
void FingerCallback::operator()(Node* node, NodeVisitor * nv)
{
ref_ptr<MatrixTransform> trans = dynamic_cast< MatrixTransform * >
(node);
sphere = api->getFrame();
if (!trans)
return;
bool isAFinger = getFinger(node);
if (hand == LEFT && isAFinger)
{
OSG_FATAL << "Adjusting left finger" << std::endl;
Vector EFVec =
sphere.leftHand.fingers[finger].position;
Vec3d erghisFingerVec = Vec3d(EFVec.getX() / X_SCALEFAC +
X_OFFSET, 0, EFVec.getY()/Y_SCALEFAC - Y_OFFSET);
Matrix m;
m.makeTranslate(erghisFingerVec);
trans->setMatrix(m);
trans->dirtyBound();
}
if (hand == RIGHT && isAFinger)
{
OSG_FATAL << "Adjusting right finger" << std::endl;
Vector EFVec =
sphere.rightHand.fingers[finger].position;
Vec3d erghisFingerVec = Vec3d(EFVec.getX() / X_SCALEFAC +
X_OFFSET, 0, EFVec.getY() / Y_SCALEFAC - Y_OFFSET);
Matrix m;
m.makeTranslate(erghisFingerVec);
trans->setMatrix(m);
trans->dirtyBound();
}
traverse(node, nv);
}
bool FingerCallback::getFinger(Node *node)
{
std::string fing = node->getName();
try{
finger = fingerTypes.at(fing);
return true;
}
catch (...)
{
return false;
}
return false;
}
...
Thank you!
Cheers,
Chris[/code]
