Fun fact: if you plot the direction vector with respect to the origin point, you get a light field. Some imaging operations, such as refocusing, are actually geometrically transformations in the light field domain.

can we not also define ray as a 1D null-space?

Qualitatively, a ray is a line that extends infinitely in one direction, defined by a starting point and a direction. This seems to back up our understanding of what we normally picture as "light rays".
