示例1: insertMatrixTransform
// Insert matrix-tranform(s)
//
// node: node to apply transform
// matrix: transformation matrix
// numberOfReplications: zero for regular transform, number of copies if replication is used.
void flt::insertMatrixTransform(osg::Node& node, const osg::Matrix& matrix, int numberOfReplications)
{
osg::ref_ptr<osg::Node> ref = &node;
osg::Node::ParentList parents = node.getParents();
// Disconnect node from parents.
for (osg::Node::ParentList::iterator itr=parents.begin();
itr!=parents.end();
++itr)
{
(*itr)->removeChild(&node);
}
// Start without transformation if replication.
osg::Matrix accumulatedMatrix = (numberOfReplications > 0)? osg::Matrix::identity() : matrix;
for (int n=0; n<=numberOfReplications; n++)
{
// Accumulate transformation for each replication.
osg::ref_ptr<osg::MatrixTransform> transform = new osg::MatrixTransform(accumulatedMatrix);
transform->setDataVariance(osg::Object::STATIC);
// Add transform to parents
for (osg::Node::ParentList::iterator itr=parents.begin();
itr!=parents.end();
++itr)
{
(*itr)->addChild(transform.get());
}
// Make primary a child of matrix transform.
transform->addChild(&node);
// Accumulate transform if multiple replications.
accumulatedMatrix *= matrix;
