A method and system allows conversion of three-dimensional data from a default coordinate frame to an arbitrary user-selected coordinate frame. The method includes obtaining position data in a default coordinate frame and transforming the data into an alternate coordinate frame defined by the user. The alternate coordinate frame can be defined by allowing the user to select a plane, an origin, and an axis, using any desired coordinate system and in any desired orientation. The transformed data allows presentation of position measurements in a form that is relevant to the user's specific application.

Why it's free to use
- Filed March 22, 2000. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended March 22, 2020.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by March 22, 2022.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
