Problem solved. The output didn't go to the same console I started the nodelet from, but the nodelet was working.

Hi,

I have the following problem. I've created a nodelet and it runs fine, when I load it in a manager I created just for this nodelet. However when I try to load it into different manager that is in the system, the onInit() just won't get called.

What can be the possible causes of this problem? I have a suspicion that some other nodelet under the manager has blocking onInit() is it possible? Can I somehow list which nodelets run under the given manager?

Hi,

I have an opencv vector cv::Vec3f and I need to transform it to other frame using tf. I came up with this solution which I don't like much, because I'll be transforming many vectors.

cv::Vec3f transformCvVector(const tf::StampedTransform & transform, const cv::Vec3f & v) {
    tf::Vector3 tfV(v[0], v[1], v[2]);
    tf::Vector3 tfRes = transform*tfV;
    return cv::Vec3f(tfRes[0], tfRes[1],tfRes[2]);

Did I miss something or is it the only way? I might be able to use bullet library instead of opencv for this, but I wasn't able to find a way how to represent other matrices than 3x3 or 4x4 which is necessary for my task.
