At one end of the first straw, glue on the next straw at 90 degrees angle to the first straw. Then, onto the same glue joint, stick the 3'rd straw to point straight up into the air, at 90 degrees to _both_ the first 2 straws. ..after the glue sets, take it to the lower left corner of your keyboard and tell us how many different ways you can put it next to the lower left keyboard corner. ;-) Orientations. ..my understanding is the yasim fdm orientation is different because Andy wrote it to learn about the standard FlightGear fdm's oritentation, which again is different from OpenGL (and Plib too?). ..these code bits are chained together with orientation rotation matrices. Math trick. ;-) -- ..med vennlig hilsen = with Kind Regards from Arnt... ;-) ...with a number of polar bear hunters in his ancestry... Scenarios always come in sets of three: best case, worst case, and just in case. _______________________________________________ Flightgear-devel mailing list [EMAIL PROTECTED] http://mail.flightgear.org/mailman/listinfo/flightgear-devel
