示例1: isBasicRootNode

/// Returns true if the given node is a basic root group with no special information.
/// Used in conjunction with UseFbxRoot option.
/// Identity transforms are considered as basic root nodes.
bool isBasicRootNode(const osg::Node &node)
{
    const osg::Group *osgGroup = node.asGroup();

    if (!osgGroup || node.asGeode())        // WriterNodeVisitor handles Geodes the "old way" (= Derived from Node, not Group as for now). Geodes may be considered "basic root nodes" when WriterNodeVisitor will be adapted.
    {
        // Geodes & such are not basic root nodes
        return false;
    }

    // Test if we've got an empty transform (= a group!)
    const osg::Transform *transform = osgGroup->asTransform();
    if (transform)
    {
        if (const osg::MatrixTransform *matrixTransform = transform->asMatrixTransform())
        {
            if (!matrixTransform->getMatrix().isIdentity())
            {
                // Non-identity matrix transform
                return false;
            }
        }
        else if (const osg::PositionAttitudeTransform *pat = transform->asPositionAttitudeTransform())
        {
            if (pat->getPosition() != osg::Vec3d() ||
                pat->getAttitude() != osg::Quat() ||
