I'm not sure how relevant this might be to the creation of gameplay in LT, where a fast/simple abstraction is usually better than a mathematically precise simulation.
But I thought this representation of how to build up curves out of the motion of linked rotating circles was pretty clever, and maybe worth a mention.

Re: Fun With Signal Processing
well, as sin(x) gives already the same results as fully simulating the rotating pointers, i think that mathematically precise calculation is sufficient 
with many rotating pointers the calculation would be r1*sin(w1*t)+r2*sin(w2*t)+r3 (...etc)
with many rotating pointers the calculation would be r1*sin(w1*t)+r2*sin(w2*t)+r3 (...etc)

This could make for a really cool in-game HUD element, potentially.

Re: Fun With Signal Processing
Oh, not to represent anything, at least not as the primary means. Just an aesthetic thing, maybe. Like a small thing that pops up, semi-transparent, whenever you're analysing (or generating) a periodic signal.

Re: Fun With Signal Processing
That's sort of why I posted this. The visual-mechanical representation of a signal generator is pretty clever, but I honestly don't know whether it has utility for LT or if it's simply a curiosity.

I think this would be really cool, especially if you add in other things like rotating cycloids or pendulem cycloids.

Not if the goal is to read the generated signal and not the actual generator.Cornflakes_91 wrote:aand a very hard to read and confusing HUD elementThymineC wrote:This could make for a really cool in-game HUD element, potentially.

as long as i dont have to read the values out of the rotating pointers, i dont have anything to say against itDWMagus wrote:Not if the goal is to read the generated signal and not the actual generator.Cornflakes_91 wrote:aand a very hard to read and confusing HUD elementThymineC wrote:This could make for a really cool in-game HUD element, potentially.

Re: Fun With Signal Processing
Wow, very cool visualization 
Never thought of Fourier in that way.
As Cornflakes says, computing the position is mathematically identical to computing the signal via summing sines.
But if someone has an idea for how it can be used in a widget, feel free

got all the trigoniometric functions visualised with rotating pointers in a circle, very easy to understand this way ^^
edit: add "in school" in an suitable spot ^^

It's a cool educational tool because it does show you how complex waves are built out of smaller ones. Bookmark'd.

That explains a lot.
Personally I would throw my inbox out of the window if that happened.

Re: Fun With Signal Processing
That's rather a lot of signal to process, isn't it?
