How can I obtain vectors like transform.up when using a TransformAccess?

I'm using a TransformAccess inside an IJobParallelForTransform job, and I'd like to be able to compute a set of vectors in this job and write them to a NativeArray<Vector3> as output.

Ideally, I would just return transformAccess.up, transformAccess.right, etc. But these aren't available in the TransformAccess API, so I think I need to compute them myself. Is there a Vector3 transformation I can apply, or do I need to do the math manually? If I have to do it manually, I think I'm overthinking the math itself, and would appreciate some pointers.
Thanks!

 

The math is pretty simple, just multiply the world vector you want by the object's world rotation.

I have not used that IJobs transform accessor you refer to, but if you have the Quaternion that is the object's world rotation (ie., normally called

transform.rotation

outside of Jobs/ECS), then the various helpers are:

transform.up

is

 transform.rotation * Vector3.up

transform.right

is

transform.rotation * Vector3.right

transform.forward

is

 transform.rotation * Vector3.forward

 

Thank you!
