I'm a bit confused at the moment: where can I have a look at the TF source? I'm looking for the various available members to extract data from a transform. http://www.ros.org/wiki/tf/ here I can't find the members documentation http://www.ros.org/wiki/tf/Tutorials/Writing%20a%20tf%20listener%20%28C%2B%2B%29 here I read there should be a getOrigin() member https://kforge.ros.org/geometry/geometry here I can't find it Has geometry been moved to github yet? I could only find geometry2. BR -- *Eng. Claudio Carbone Embedded Systems Design* P.IVA: 11688471009 tel: +393809017424 email: Send email My linkedin profile My Portfolio My portfolio site
