Relative Positions

November 30, 2011 - 12:33am #1

I've scoured the forums and I can't seem to find any related topics.

I'm trying to find the position of a target relative to another target. I've tried multiplying the child model view matrix by the inverse of the parent model view matrix but the coordinates seem to change with the position of the device even though the targets remain at a constant position. Since they targets remain at a constant relative position, shouldn't the matrix stay the same (ignoring jitter of course)?

I also discovered the inverse function included with the SampleMath example class is incorrect. A matrix multiplied by it's inverse should result in an identity matrix, but the results were incorrect. I have a corrected version if anyone is interested.

Any help would be greatly appreciated.

hello kim I am new with vuforia and unity

I have the same problem, I need to find the position and orientation of an Image Target with respect to another Image Target. Also find the position and orientation of a multi target with respect to an image target, try to look at the link that you left but it is fallen, I thank you for your help
