Ahhhh, The good old days!!
I came in at version 2.
After searching for my first 3D app. I found a ridiculous 3D add-on to ACLT, then Design Workshop [which never excited me] and then finally, Eureka!! SketchUp!!
After pulling up a couple of squares, texturing them, importing a Palm tree, turning on the shadows and orbiting...I was hooked!...say about 30 min. flat!!
SU in those days was without text, dimensions, transparency and a lot more obviously, but was still incredibly useful.
SkechUp output was... well just that. This was before the Dennis or Marshall techniques and photo realism was just an impossible dream. Piranesi did however offer the chance of post processing at that early stage.
The forum consisted of three, then four sub sections and there was a core of about 20 contributors including about 3 @Last guys. Very exciting, innovative times.
People I remember from then include Ross, Mike, Susan Sorger, Grant Marshall, Kevin Hui [PushPullBar] and Frank [said in a whisper].
Ah well...we all move on
[And although this was all a while ago I still don't quite feel prehistoric ]
