Vectors example attached.

is it possible ?

Thanks!

Hi guypld,

As you discovered while working on this directly with Support, the ray information is not exposed in Motive. It is possible to get this information through the Motive API, however.

You should be able to retrieve the X, Y, and Z location out of the cameras, through the API, using the following:

You can also retrieve the ray information using:

Best,
Steven
