It does appear to be mine. I released it publicly years ago with the usual restriction that credit for myself and Franz Joseph Schnaubelt must be given, but a lot of uncredited images and animations have shown up over the years, as well as kitbashes, re-used texture maps, etc. There have been a lot of credited and by-permission uses as well, so I figure it mostly balances out.
Couple of fun facts:
1. If you look at the original 3D model in just the right place with light hitting it at just the right angle, Franz Joseph's signature shows up in the specular map.
2. The 3D model was built from hi-res scans of the FJ Booklet of General Plans and is accurate to within about 1/100 of an inch (at plan scale). And yet, despite my best efforts, I still made a couple of major errors, mostly in the shape of certain details surrounding the deflector dish.
3. When I built this model, I was one of the first people, at least within the amateur 3D modeler community, to use what I called the "window box" technique. Instead of just glowing rectangles, I built hollow boxes with illuminated texture maps inside the window openings for an added sense of depth and realism when the model was animated. Nothing special by today's standards but 20 years ago it was considered pretty awesome.
4. I created a poster-size print of the model with a classic 3/4 view and 4 orthographic views, technical details, etc. The print was framed and donated to a charity auction and sold for something like $350 as I recall. It was a signed and numbered print, one of only two (I still have the second one). It was also authorized by Franz Joseph's daughter, Karen Dick, and came with a certificate of authenticity bearing her signature. It would be interesting to know what ever happened to it.
Damn, Vektor - thanks for making me feel old. I remember when you first put that thing out!
