Hey !

So I send a mail some time ago to the list and got no answer, so I guess it was not really clear.

I come now with a more simple version of my problem.

I have two cubes,

cube A

translationXYZ 0 0 0

rotationXYZ 0 0 0

and cube B

translationXYZ 12 5 6

rotationXYZ 0 0 0

now I want to calculate with only thoses informations, the rotations in X Y and Z for cube A to look at cube B. (numbers are irrelevent, I want to make the algorythme)

I have tryed many things, with trigonometry, learned about Gimbal lock, read everything I could about euler angles, etc ... result is it's not working right.

I attached an exemple patch. The math inside are based on the help I got on a math forum. It quite look like the thing I was trying to do but it doesn"t work better :)

Anybody ? Any idea?

cheers

PS : I try to do that to calculate joint orientations of kinect skeleton. and even though there might be other solutions(wich I be glad to know about), now it's a personal affair, I WANT TO DO IT !!! 2 WEEKS I'VE BEEN TRYING !! AAARGH
