Yes, it certainly is. This was not possible before as light shafts were a faked effect for looking over the edges of objects at lights, but now, light shafts can be easily created as this is the very purpose of volumetric lighting. They can be viewed from most angles. To do this you just need to set up a domain for the volumetric lighting. This can be your whole world. Just add in an “exponential height fog” class, set it to have volumetric lighting in the details panel, and then just crank up the extinction scale to play around with it…
