You're correct. We used RayDream, which has an introductory version
priced aroun $100. The full version is a bit more ($300-$400 I think).
Some details on the renderings are at:

I haven't been keeping track of the Lego CAD situation recently, but when
we started work (February 1999) the only tool available for Mac with an
existing Lego part library was POVRay, which is pretty nasty in terms of
constructing scenes - I wanted drag-and-drop editing not text file
editing.
I would've considered using a PC if the *ideal* solution was available,
but at the time I didn't find anything. I expect the tools have evolved a
bit and that if I were to make the same evaluation now I might reach a
different conclusion. I also have to admit I wasn't looking *too* hard
since I really didn't want to run out and buy a PC or two just to write
the book.
Constructing all the pieces ourselves had certain advantages - such as
cambering the corners of bricks/beams/plates to make seams more visible.
We were trying to walk the line between photo-realistic rendering and
illustration. Technical illustration, such as that used in the Lego
instructions themselves, is definitely better for showing how to put
things together. However the 3D look had a certain appeal, and we stuck
with it (partly as a way to differentiate our book from Lego's
instructions). Next time out we'll improve some of the trouble spots.
