I hate trig

SImple, enough. If you have, say, 4 nodes, the first is at 45, the second at 90+45, the third at 180+45, and the fourth at 360-45. Now, to find the coordinates, simple multiply each angle by (pi / 180) to convert to radians, and use this formula:

Code:

---

p.x = center.x + radius * cos(radianMeasure)
p.y = center .y + radius * sin(radianMeasure)

---

Where radianMeasure is the degree angle converted to radians, p and center are POINTAPI, radius is, of course, the distance from the center to each node.

I chose to start at 45, because you will then get a nice looking X shape. You should start the count at (angleBetween / 2).

Z.

Hmmm well the user can do any from 1 up to n hosts. So I would have to start a spoke somewhere, and then each additional spoke is (360 / hosts) degrees away...

uhn I really hate trig stuff. I much prefer proper coding :)

That's what I am saying. Start the first host at (360 / hosts) / 2, and increase that count by (360 / hosts) each time.

Z.

You wanna code it for me ?
I'll swap for the tracert+ping code ;)

Honestly, even the simplest of things elude you!

What he said was:

LengthOfSpoke = (((pi * 42)/6) * AvgNoOfBowelMvmntsThisWeek) + _

centerpoint + ((100/maxping)*pingsize) *cos( ((360/maxnodes)*currentnode)*(pi / 180 ))

Easy innit! :rolleyes:

For ease-of-use, use a different coordinate system that has your computer's centre at 0,0. Then for each computer use X = Cos((ComputerNumber / Computers) * 360 * (Pi / 180)) * (length you want it to be away from), and set Y with the Sin() function in the same way.

People, im looking for code, not comments :)

nodex = centerpoint + ((100/maxping)*pingsize) *cos( ((360/maxnodes)*currentnode)*(pi / 180 ))

nodey = centerpoint + ((100/maxping)*pingsize) *sin( ((360/maxnodes)*currentnode)*(pi / 180 ))

there's some rough maths for you you moaning git! ;)

Don't know if it works - I've just come back from the pub and maths isn't my strong point anyway. If it's useless and wrong then it's useless and wrong. I don't care.... :)

Check your email. Don't toy with me right now :)
Anyway. I just need some code to copy and paste. I'm in no mood to rub brain cells together. I'm in more of a mood to wet them with a bit of bulmers...

Not got an eMail yet matey, servers are running slow. Thought you hadn't bothered replying ;)

The best I can offer is that you put your wotsit on a server somewhere and I'll download it and have a look. I can't post code based on what you've put here...

www.coolground.com/plenderj/4.zip

it does a tracert to 4 addresses at the moment.
user will be able to tracert to 1 or n hosts.
records all the info.
have to display.

asjfoi!

Got your mail and replied now. I'm look at the project as well.

What happened at the bottom of you post? Bang you head against the keyboard?

bout of rage.
got some groove armada (at the river) on at the minute, so its all good.

Ok, I've looked at that project and it seems to get in an infinite loop. The sHostIP never changes and as it's being compared at one point to get out of the loop - it never makes it.

Is this just me being thick?

Its you being thick.
tracert works ; trust me. its complicated.
just do the trig :)

I'm struggling with it because I can't test it because it doesn't work.

I'll try it at home where I can look at it without being hidden behind all the complicated network ****e and I can get some ping values back.

Speak to you in an hour or so.

Holy crap jamie, you don't know euler transformation?

D*MN!!! It ate my post! I spent the last half an hour writing it :(

Ok so I'm gonna post here just the code. And this one I'm sure it works :D

VB Code:

Angle = (Pi * 2 * Host) / NumHosts
HostX = CircleX + Cos(Angle) * CircleRadius
HostY = CircleY + Sin(Angle) * CircleRadius

Let's see... Pi is obviously 3.1415926..., Host is the number of the host you're drawing, NumHosts is the number of hosts, CircleX/Y is the center of the "circle of hosts", and CircleRadius is the radius of that circle.

Hope that helps! :)

This is kinda what im after.
Each circle on the way is each router on the route ...

you can define a complex offset unit to traverse the rotation
Cu=1*e^j2pi/n
and for each singly likned node shown in your figure, increment by Cu*Cn
Cn=u*ping*e^j0
These are polar representation of complex values, the transformation to cartesian is:
r*e^(j*theta)=cos(theta)+jsin(theta)

Christ almighty. All I want is a .frm given to me that'll do the job :)

jamie, you should learn this immediately, it'll be good for you :) Does the routes split up?

Sorry but I don't know much about routes and all :D
Do these things branch out into others, like a tree?

Jamie,

I fail to see what's wrong with the calculations that Jotaf and I posted. They're both pretty similar (mine's not been tested though) but in Jotaf's I guess you'd replace "radius" with the server ping.

PS - I completely fail to see what Kedaman's on about at all. No change there then. :rolleyes:

I think I need to buy some more IQ.

Ked; No the routes dont split. Just a straight line out at an angle with the nodes along the route along that line.

Rest; I dont wanna do no work. I'm anti-trig. I need a .frm

If you use complex values you avoid trigs at almost all costs, eulers formula is unavoidable though, but without it you are no programmer.
Jamie, you learn Trigs at 7'th year or something in basic school here, how come you've avoided them so far? No, you won't survive without them further on.

Complex values have two faces, they are both polar and cartesian, which makes them an excellent tool :) You can though use trigonometry all the time for some transformation, but complex values enhance your generic thinking and makes it easier for you, when you have to do a long series you might win both runtime performance and developement time.

I studied complex numbers and polar co-ordinates and all that about 3 years ago. Since then the only time I needed trig was for Craft and I finished the trig part of that ages ago

Sent you an frm with some **** in.

Can't test it 'cos your shoddy code doesn't work properly. It may end up drawing the images completely off the screen - you'll have to step through in a debug to see what it does.

It never gets to that point on mine, it just goes into an endless loop. Don't complain if it doesn't work, because coding trig blind is insane and is guaranteed not to work first time.

Well the tracert works for me :)
Anyway yeah its drawing stuff all in the centre...

Hmm the code kinda works. It does draw stuff (we're drawing otherNode.hdc btw). Anyway, it only draws the destination node, not the nodes inbetween...

Are you pinging all the servers inbetween?

If so, and you're storing the ping values in an array then you can easily get it to draw the ones inbetween.

That just loops through the troute wotsit array. If there are other gubbins then just add them in.

I'll take another look and see if I missed anything. It's rather hard, not being able to see what I'm doing and all...

What's dis hoptime thing for?

The hoptime is the time to that node. Thats also gonna be the distance between nodes

right, gissa mo and I'll send you something else

Sent you some porn in your eMail.

u didnt send me natin but text

I sent you an frm

i only got the first one from you.

... keep talking, im nearly at 4096 ;)

Idiot boy!

I sent you another .frm with different code.

never got it

as attached

like I say - dunno what's it going to do?

:eek: I only learned basic trig last year (9th grade) :p

And I don't have the slightest clue as to those "complex values" :D

Ben, don't do that again, he will just follow after you like a baby...

Jamie, it's time for you for a quick lesson in trigonometry.

Code:

---

|\
|a\
|  \
|  \C
|A  \
|    \
|__B___\

---

cos(a) = A/C

sin(a) = B/C

tan(a) = B/A

**** off ked :)
I know trigonometry, and used be very good at it. I used to do applied maths for god sake.

Anyway I just dont like doing trig.
Its a pain in the ass

The way I learned the trigonometric ratios was as follows :

Sally O'Hara , Caught A Homo , Touching Our Asses

Sin=Opposite / Hypotheneus
Cos = Adjacent / Hypotheneus
Tan = Opposite / Adjacent

Ked,

He's been a great help to me with Sentience so I figure the least I could do is try and help him with this. Of course, I've probably made a complete town halls of it but I had to make the effort.

I agree with your philosophy (as it's mine also) that you shouldn't just do a task for someone, you should show them how it's done and let them do it themselves.

Jesus christ I was nearly an expert on trig about 3 years ago, but not now. Its just a pain in the ass. Better yet ; a royal pain in the ass :)

LOL!!!!!

Typical bloody Irish!!!

I like it!

I swwear to god, ever since the junior certificate when we were doing trig first I've used that little ditty :)

Jamie, I wonder what it will become of you :p

Hey, do you know how my teacher thaught me that thing?

"Just study it and shut up."

:D

Btw Keda, couldn't you find a better avatar?... :)

Right after some nice code from arbiter, and a few modifications here and there, here is a sample tracert jobby. I've removed all the winsock code, and this app will just make up a route and display it.

Any suggestions though ?

*woops*

Very nice Plend, very nice.

Very sexy.

But its all bunched up and queer.
I also want to somehow tell the user the hop times and hosts etc...

Make the screen resizable, the graphics a tad smaller and put the hop times next to the hop points. Maybe have them visible when the mouse moves over a 'tendril'.

It's bound to look bunched up and queer in the centre as you've got a lot of graphics in the centre of a circle. If you started them a number of pixels out from the centre then it would look a little more spaced out. Bit like you really.

PS - Thanks for those Sentience screenshots :rolleyes: I don't need them anymore now...

Righto I'll delete them then

Plankton.

You should have sent me those yesterday!

And after I cooked my head doing that trig for you...

humph

Well, in a couple of versions time I'd like another of your legendary bug reports from Sentience as payment. ;)

They really are quite detailed and really help to tidy the game.
