archimg.com — Collected works by Stephen R. Mallon, RA
is something I did for years.
During my career as an architectural illustrator, I built thousands of 3D CAD models. Renderings of these along with animated fly-arounds and walk-throughs helped my clients to visualize what they were getting themselves into before starting construction. There were far too many of these projects to show here, but I've picked a couple of imaginary projects I did just for fun.
If I stumble across a month of rainy Saturdays (and I'm not busy collecting animals two by two), I might animate these, adding the musical (or not) sounds the contraptions would make when set into motion.
