Is asburger close to the Whopper™ or BigMAC™ in taste?

Imagine that the Laser beam itself is invisible and that the coloured beam is a targetting help and the problem is solved.

lol everyone on the internet has aspergers these days. look, i have a negative opinion about something, must be aspergers.

as for your opinion about lasers.. stupid and wrong. high powered lasers have very visible beams. it doesn't require a dusty atmosphere to show up.

different colored lasers, sure, that's easy, each laser is actually a pair of emitters that fire modulated IR at frequencies just offset enough through a single emitter that, thanks to the interaction with the gasses in the atmosphere, cause the molecules to fluoresce in the wavelengths that we perceive as red green and blue. Now that said, I have a giant bag of BS that I would like to sell... ( for MC if at all possible)

'Laser' stands for "Light Amplification by Stimulated Emission of Radiation", a device that focuses an amplified beam of light on a small surface area. The medium laser uses this intensified beam of light to damage targets by heating them to melting temperatures.

Im sure its been posted somewhere, but this is what the BT term is. Since its condensed, focused Radiation, that gives a slight reasoning. Back to work.

And so it be told, that again on this day, the 10th of September, after 15 reply emails to a dead topic of no stimulating conversation, rhyme or reason, I logged in specifically with the sole purpose to unfollow previously referenced dead topic.

Perhaps I misunderstood the question, but most of the people will see green, if there are blue and yellow transparent objects on the path of their "eyebeam".

As you've mentioned - we only are able to see laser colors due to reflections on dust particles etc. ( not coherent any more etc. ) , so I see no reason why we shouldn't percieve combination of blue and yellow as green in this case (w/o any compounding ) ;) ... and for sure - it's just a game ;)


and lol @ original post date .. someone got me

I know this is a game and there is a large element of suspension of disbelief, but I have a real issue with the way laser colours are shown in the centurion vid. Even more so with the given explanation in the locked thread. (I would have posted this there if it hadn't been locked.)

Lasers being visible?... Ok, can live with that, battlefields tend to be very smoky/dusty environments after all.

But lasers compounding to different colours? ... Maybe its my aspergers acting up, but that REALLY rubs me the wrong way...

Lasers are coherent light, meaning it is VERY directed and focused. To compound 2 different wavelengths they HAVE to be travelling parallel in the exact same plane. To get the beams to travel in parallel and close enough to affect eachother they HAVE to share a focusing device (lens or mirror), which makes it impossible for two seperate and distinct lasers (IE not sharing a focusing device) to ever compound in the manner shown in the video.

Nevermind the fact that combining two waves CHANGES the properties of said wave (I even wrote a wave simulator program doing just that in Turbo Pascal back in high school). A combination of a small and a medium laser would (under ideal circumstances described above) create a combined laser, not two seperate "projectiles". It could also cause the resulting wave to amplify itself, then cancel itself out, then amplify itself... ((Side note: isn't that how pulse lasers work?))

Hmmm... ok let me try some speculation.

The HUD that the pilot sees is rendered using a combination of a real-time representation of the battlefield, collected by on-board cameras and computer generated aides that help the pilot by providing tactical information as well as adding different visual effects to different weapons that would otherwise be invisible so that the pilot can be more aware of battlefield conditions. The HUD displayed in the pilot's helmet makes the lasers look like they're different colors so the pilot can easily and intuitively determine the intensity of the beams being fired during battle.

Convincing enough? ;)

Thats my point, to me (and like I said, it might just be my aspergers) its immersion breaking. Its not going to stop me playing the game, but its something that will irritate me every time I see it, reducing my fun.

Thats the main reason I made this thread... and well, if I'm the only one I'll just shut up and go mutter in the corner :)

Your pilot name is immersion breaking.

well realistically, there wouldn't be laser weapons. or giant mechs with plated glass cockpits.

as far as mechs go realistically, we're more likely to get power armor than full blown mechs, although I would love a patlabor or an arm slave

OR here is a IDEA they have technology we have not seen yet? Maybe their definition of "Laser" is different then ours?

RL Example? OK, look at how our view of the world changed when we were able to find out the world wasn't flat but round. Want another? How about when we found out that we as a planet actually rotate around the sun not the other way around.

Chalk it up to "its the future, its Tech cannot possibly understand because we have no current day equivalent. The lasers we have now, and there for the definition of lasers are only what we know now, and subject to change like anything else.

You are I assume correct on your assessment on the probability of compounding lasers.

However, the perception of colour (and I apologise in advance for my imperial spelling of the word) is performed in the brain based on the feedback it gets from our eyes, which only see colour as a balance between red green and blue.
When we see two coloured light sources in close proximity our brains translate this as a single coloured light source - a blend of the two. This is how the pixels on a tv or computer screen works. The same will happen with laser sources, you can do this now with different coloured laser pointers.

Lasers are colorful things that go PEWPEWPEW. Haven't you watched any movie at all?
