Thank you all!
We have 12 Eagle cameras from Motion Analysis in our house... The shooting took half a day... I use EvaRT from MA to track the markers and the solving is done in Solver Interface(SI), also MA software.... The computers are Dell Xeon somthing!

The data is then imported to Motionbuilder and tweeked there (just an amazing animation package!!) later I import it back to Maya for rendering!
