Some time ago I started making a game. Then the game didn't come together the way I wanted, so I made a new game. Then,... No wait, this isn't a monty python routine. The second attempt actually produced a result that I'm publishing. Just a proof of concept, far from an actually finished game...

This is a very basic question about algebra, but it's been... quite a while, and my education sucks anyways. Googling didn't really yield anything, I'm probably not looking for the right terms. So to illustrate, let's say I have a fraction with X on both sides, and I have the ratio, for example...

It's been a while since I played with special relativity, I seem to have forgotten most of it. And right now, I'm having a problem that has acceleration thrown in, and it's doing weird things to my brain. The first question - constant acceleration. Let's assume a spacecraft constantly...

Right now, mesh groups in Orbiter are limited to something like 65000+ vertices per group. I assume that the exact number is 65535 and that this is because the meshgroups are indexed with an unsigned short, or potentially with a signed int. I don't know, I haven't looked at the code yet. This...

We have quite a few really cool spaceplanes with decent simulations. The XR-series most of all, but also the DG IV, the starliner, and there might be some I've missed. We have nothing comparable for purely orbital operations like transfers. There's the dragonfly, which has electric and...

This is probably a dumb question, but I can't find the answer by googling. If a^x = b, and I have a and b, what's the operation to find x? (I assume there is one?)

Trying to get some stuff from Blender to Orbiter, and mostly failing spectacularly. As far as I can see, there are 2 tools: The one from vlad, which sounds excellent from the description, but is out of date and not compatible with Blender 2.8+ if I gathered that correctly...

So I was fooling around with some stuff, and I accidentally discovered a scaling rule when messing with one of my functions. This is not me wanting to toot my horn, I'm sure the rule is well understood for a couple hundred years, I just want to know if I can make my life easier and cut out some...

I am wondering a bit about how an "industrialised earth orbit" is sometimes portrayed, and I thought it would be cool to have a discussion about it here. What I don't want to discuss is how we get there. There's plenty of models around, all with their own issues, but for this I really want to...

I'm looking for a curve that's roughly shaped like this: Sigmoid alone won't do the trick because I need two bends in the same direction (and also lying on its side, but that part would probably be doable). I'm trying to concoct something together, but I suck at this stuff...

Pretty straight-forward question to which my google-fu somehow won't spit out an answer: If I have the inclination of two objects, as well as the longitude of the ascending node, how do I calculate their relative inclination? Do I have to go through all the rotation shenanigans or is there a...

I just realised with some surprise that we don't have a sub-forum for speculative spaceflight discussions that are not directly math- or astronomy related, so I'm posting this here. I'm wondering about transfer stations. They are often mentioned whenever the talk is about "space ports" or a...

I just learned Freeman Dyson, among SF-fans perhaps best known as the inventor of the concept of the dyson swarm and dyson sphere, and among scientists for so many significant contributions it's difficult to come up with a comprehensive list, has passed two days ago, on the 28th, aged 96...

Important Note: This is a developer resource to be used in add-on creation, not a playable add-on in and of itself The rather large-ish table that IMS2 has become continues to drop some morsels, this is another one of them. Granted, I don't see this one getting much use, since it's only...

This is a developer resource for use in orbiter C++ projects, not an add-on in its own right. Title says it pretty much, for details about features and usage visit the github page: https://github.com/TheNewBob/Olog

So my brain lately started of its own accord to pick together bits and pieces for a science fiction setting in a run-down dyson swarm. I find the idea appealing since it offers a lot of common space opera tropes like world hopping, exotic cultures and ancient abandoned ruins packed with...

Y2K was mostly panic. Admin edit: Fair warning, the page behind this link contains an acronym which spells out a rude word. This one seems to be for real, though. A serious security flaw in the intel cpu architecture, going back a decade. The only possible countermeasures are developing a new...

I noticed that the viewport size is passed to clbkLoadPanel2D at every call. This might be mere convenience, or it might indicate that the viewport size could actually change at runtime. As far as I know, Orbiter is not resizable in windowed mode, so I think it's the former. I'm just asking to...

So my laptop died very unexpectedly of... I'm not exactly sure what, but the fan and power led are the only things I can say with any certainty are still working. Meaning I currently can't code and much less play No Man's Sky, because I don't want to swamp my wife's Laptop with a few Gigabytes...

Continuing work on IMS2, I once again find my lack of knowledge one of the biggest hinderances. And once again I think an engineering subforum along with math&physics and astronomy might be a good thing. I want to put a bit more realism into power distribution than in the original, and have...
