Plane definition

Hi all,

 

maybe not the most intelligent question, but could anyone tell me what the plane definition is made from. For instance the Evaluate surface component gives a plane output with four values. The first three denote the normal vector of the plane. The fourth looks like a z-value, but it is not, see the definition below.

 

Maybe more general, how does one know what the values of output parameters denote?

 

Regards, Roel.

I'm not sure what it was in version 0.6x. But in version 0.7.0045 it is now a different format with an Origin and a Vector. (Not much help I know)
