Interactive notebook: a WIP

I'm in the process of constructing an interactive notebook for use in Celestia, using Anim8or to design its components. It's interactive in the sense that the viewer can turn its pages, not that new entries can be written from within Celestia. Writing on a page has to be done "out of band" by painting the surface texture for each leaf of the notebook.

A sub-project was to create what looks like a taped-in photograph which will be used in several places. I have made it available on DeviantArt at

Orion's Arm Wormholes

As another distraction, I've been working on a Celestia Addon which displays the wormhole connections used in the Orion's Arm Universe

Algae and Fish Farming

Production of basic foods in space require plenty of sunlight as well as some gravity. While the plants and animals might not mind microgravity, production facilities work better when there's something pulling the product in particular directions. The toruses counter-rotate in order to minimize torques on the docking facilities.

ECS-5 Norway at Pell

Using Troutweaver's models, I've created a very preliminary and incomplete animation of the warship ECS-5 Norway entering the Pell system. It's about 98 seconds long. The original video is 1024x768.  By default, Youtube shows it at a much lower resolution, but if your browser has a video downloader plugin, you can download it at its full size.

 The video can be seen at

Loading a Can Hauler

After a bit of struggling and letting my subconscious work on it overnight, here's an animation of a can being loaded into the hauler.

The models of the "hero" can and of the ships were created by Troutweaver.

I created the "depot" where the cans are stored while waiting for transshipment and a simplified can design to reduce graphics overhead.

The 640x480 video can be watched at

Loading a Can Hauler

Troutweaver was kind enough to send me a few more of his models.

Here's a Can Hauler being loaded. This is a "diorama". The models (cans, pusher and hauler) are being drawn by Celestia in fixed relationships with one another. I might be able to make it more active with the pusher actually shoving cans around, but that'll take some work.

 I think the pilot of the pusher is going to catch hell from the can hauler's cargomaster. The cans are being loaded in the wrong order: they should be loaded around the circumference starting close to the engines. That way the can hauler can leave with only a partial load and not be off balance.

(I didn't think of that problem until after I'd written the "catalog" for Celestia. Changing it would be enough work that I don't feel like doing that just yet.)
