Planetary Logbook – MOON

June 2, 2019

nB Capture

To show how the Planetary Display Logbook would work, I’ve taken a set of 6 false color images of the moon from the LRO, where color represents altitude – north and south polar views, nearside and farside faces, and east and west sides.  I’ve used those to fill out the 32 panels of a Planetary Display Logbook, so there’s a completed planetary display to show how it could work.

n6 CaptureThis will probably eventually be available from DriveThruRPG one way or another, but for now it’s just an alpha draft as we work it all out.  If you’ve bought the Logbook from us already and you’d like to get a copy, contact us, and we’ll get it to you one way or another.

Working from a source like that, there are parts of the image that are cut out.  So, if you put all the pieces together, you’d still have breaks between the sections.  Because the logbook is an abstraction, there are things that get missed or that get lost in translation from the flat form (which is already an abstraction) to the facets of the truncated icosahedron. I’m sure there are cartographic tools and methods that would do a better translation, but for gaming purposes, I think this is going to be good enough.

The image quality and resolution of the source imagery is a bigger issue for me right now.  These are large-ish images, but since they are using just a segment of the image for each page, they get somewhat pixelated when just a portion is used for a page.

With this getting worked out, we’ll probably have some version of this included with the Zvezda adventure, when that comes out.  So consider this another teaser on that front, as well.
