Math.COS, Math.sin = Math.HELP

Hi all

I was hoping to create a JS script to move objects from the common center based on their current location. I thought to use an element of single selected path as the center based on its position x / y and width/height. Using this reference point that the script would then move away all other elements of the path of this central point based on a desired amount and with uniform increases, account required to their current location of this Center. I was thinking about cos and sin would be my friend in this case, but they seem to have become my enemy instead. ;-)

Does this sound feasible? What Miss me, hurt, misinterpretation? Here's an attempt at non-working, I can't fix things, maybe I was close and missed or maybe I am so far and its complex more than I thought. However at this point I'm confused through my various attempts which is only one of them.

Thanks in advance for any help and health mental someone can provide.

// Example failed code, nonworking concept
var docID = app.activeDocument;
var s0 = docID.selection[0];
pID = docID.pathItems;
var xn, yn;
var stepNum = 20;
for (var i = 0; i < pID.length; i++) {
    var p = pID[i];
    var dx = ((s0.position[0] + s0.width) / 2 - (p.position[0] + p.width) / 2);
    var dy = ((s0.position[1] + s0.height) / 2 - (p.position[1] + p.height) / 2);
    xn = Math.cos(Number(dx) * Math.PI / 180)+stepNum;
    yn = Math.sin(Number(dy) * Math.PI / 180)+stepNum;
    var moveMatrix = app.getTranslationMatrix(xn, yn);
    p.transform(moveMatrix);
    stepNum+=stepNum;
}

Hi W_J_T, here's a way to do what I think you want to do, I put comment the increment so everything will "explode" the same distance, do not know if it is you need.

first of all, I suggest the calculation of the center of the object selected out of the loop, you only need to do the math once.

In addition, (s0.position[0] + s0.width) / 2 has a problem, it will not give you the Center, check below

// calculate Selection center position
var cx = s0.position[0] + s0.width/2;
var cy = s0.position[1] + s0.height/2;

then we're going to loop through all the elements and calculate their Center

        // calculate pathItem's center position
        var px = p.position[0] + p.width/2;
        var py = p.position[1] + p.height/2;

We will pass the calculation of the distance from the center of the selection in the center of each item, we don't need this method, other methods may use this information.

now, your real question on Sin / Cos

xn = Math.cos(Number(dx) * Math.PI / 180)+stepNum;

Sin (angle) and cos (angle) expect angles in Radians, you not provide any angle in the formula above. We need calculate the angle between the selection and each path Center

        // get the angle formed between selection's center and current path's center
        var angle = get2pointAngle ([cx,cy], [px,py]);

as soon as we have the angle we can apply to our variable 'Explosion', I guess is stepNum and get its x and is distance he needs to walk away selection

        // the distance to move is "stepNum" in the same direction as the angle found previously, get x and y vectors
        var dx = stepNum*Math.cos(angle);// distance x
        var dy = stepNum*Math.sin(angle);// distance y

everything remains to be done is to move the paths, here is the whole thing

// Explosion, AKA move all items away from selection
// carlos canto
// http://forums.adobe.com/thread/1382853?tstart=0

var docID = app.activeDocument;
var s0 = docID.selection[0];
pID = docID.pathItems;

var stepNum = 20; // this is the distance to "explode"

// calculate Selection center position
var cx = s0.position[0] + s0.width/2;
var cy = s0.position[1] + s0.height/2;

for (var i = 0; i < pID.length; i++) {
    var p = pID[i];

    // skip selected item
    if (!p.selected) {
        // calculate pathItem's center position
        var px = p.position[0] + p.width/2;
        var py = p.position[1] + p.height/2;

        // get the angle formed between selection's center and current path's center
        var angle = get2pointAngle ([cx,cy], [px,py]);

        // the distance to move is "stepNum" in the same direction as the angle found previously, get x and y vectors
        var dx = stepNum*Math.cos(angle);// distance x
        var dy = stepNum*Math.sin(angle);// distance y

        var moveMatrix = app.getTranslationMatrix(dx, dy);
        p.transform(moveMatrix);
        //stepNum+=stepNum;
    }
}

// return the angle from p1 to p2 in Radians. p1 is the origin, p2 rotates around p1
function get2pointAngle(p1, p2) {
    var angl = Math.atan2(p2[1] - p1[1], p2[0] - p1[0]);
    if (angl<0) {   // atan2 returns angles from 0 to Pi, if angle is negative it means is over 180 deg or over Pi, add 360 deg or 2Pi, to get the absolute Positive angle from 0-360 deg
        angl = angl + 2*Math.PI;
    }
  return angl;

If you are familiar with the table-top games, I'm doing a calculator point - buy for the capabilities of the player, in the standard fassion.

You can configure objects to associate each value of ComboBox with the total corresponding. Then perform a loop on the drop-down list boxes, get the value of each, search the total associated with the value and add it to a running sum. Then, set the value of the field to the sum. For example, if you named stat1 thanks stat6 drop-down list boxes, the calculation script customized to the total text box might look like:
```
// Custom Calculate script for text field
(function () {

    var v, sum = 0;

    // Set up lookup tables to associate combo box values with a total
    var t1 = {10:0, 11:1, 12:2, 13:3, 14:5, 15:5, 16:9, 17:12, 18:16};
    var t2 = {8:0, 9:1, 10:2, 11:3, 12:4, 13:5, 14:7, 15:9, 16:11, 17:14, 18:18};

    // Loop through the combo boxes and add up totals
    for (var i = 1; i < 7; i++) {
        v = getField("stat" + i).value;
        sum += (i !== 6) ? t1[v] : t2[v];
     }

    // Set this field value to the sum
    event.value = sum;

})();
```
You must use the same naming convention you can easily browse the fields, but you should get the idea.

Offline files disappear after accident of SIN. Help, please!

I keep my "My Documents" folder on a NAS box and make available offline when I travel. When the NAS box has crashed, my files were still available. When I have resurected the NAS and created a new Division with the same name for my "My Documents", rather than synchronize folders offline to the NAS, almost all offline files have been deleted.

The really bad news is that the last full backup of the NAS is 10 days!

If anyone knows how to restore offline files, please help!

What replaced the motion Math Script

Again, I've read an old AE book "Angie Taylor - Creative After Effects 5.0
She was going through a project which involved using MOTION MATH scripts to synchronize the audio levels of mouth shapes. It was described as being very simple to use.
Given that I could not find the Script where she said it would be, I rose Motion Math help online and came across a post from 2007 which stated that it was abolished.
What is now used instead it or how I can recreate what he used to do. I imagine that something using expressions probably replaced.
Until you bark at me on reading such an old book, these books show a few interesting examples and even some stuff that only new books, that I learned how to use Motion Sketch to animate an object on the rhythm of the music in real time. You can get these old books for less than $5 and a little for even a $1 on Amazon.com and given that the program was more simple then the learning curve seems to be less overwhelming.
I use CS4 on Mac, and I have AE CS4 Visual effects and Compositing of Mark Christiansen
Thanks in advance

Cris: You could say that motion Math was replaced by expressions.

Expressions are not only much more deep and versatile. Unlike the Math movement, they are 'live' in the sense that they continue working without having to the Cook into keyframes. Allows you to create live connections between properties, instead of an operation as a query time Math script.

In this particular case, you can use the "Convert Audio to keyframes" keyframe Assistant on the audio layer. This will create a new layer with keyframes that represent the sound levels for left, right and two channels. You can then use expressions to connect any property of any layer of these values and keep the expressions of refining as much as you want. I fear that the details are beyond what I could explain in one post, but there is even a whole book on expressions now: after effects Expressions, by Marcus Geduld. There are a bunch of other resources as well. Try using After Effects expressions section, which surely has links to more information about expressions.

amplification of the strain by using the cDAQ

Hello

I am a newbie in the use of DAQ hardware and hope someone can help out me.

I recently bought a cDAQ with the NI 9237 to measure the strains. The strains that I try to measure are very small 1 series micro. A bit of research showed me that I need to amplify the signal to measure these small strains (correct me if I'm wrong). But I'm not able to find amplifiers for the cDAQ.So, the questions I have are-

1. is it possible to measure these small strains (1 strain micro) using the cDAQ? If so, do I need an amplifier?

2. If I need an amplifier, are there more specific for the cDAQ with the 9237? If this is not the case, how and where can I get one?

Thank you

SID

SID,

These results were very shocking for me also, so I looked into it further. It seems that the 9237 can do better. Assuming you're within 5 degrees of the calibration temperature (25 ° C), 9237. 05% of span of error and. 05% offset error. With the range of configuration and 25mV/V full-bridge, you can calculate the absolute accuracy of the 9237 with the following formula. (Sound of full-bridge = 0.9 microV/V)

absolute accuracy = (gain error * reading) + (error offset * range) + (noise)

Do the math, we get

25mV/V + / 25.9 microV/V

In a full-bridge configuration: V/Vex =-(Gauge Factor) * strain

With a typical GF of ~ 2.0, we can say that the accuracy of the strain will be

12.5 mm/m + / microm 12.95/m

It's a little more in the range that you hoped for. Sorry for the confusion.

If this does not work for you, we sell solutions PXI who will be able to measure more precisely. Similar math help and type of configuration of full-bridge with SMU 4330 plug, we get:

12.5 mm/m + / 3.48 microm/m

In my view, that it is card data acquisition based on a bridge more precise and accurate that we sell. It requires a controller/chasis PXI.

Please let me know if you have any other questions!

I can't download Windows Media Player 12 Ms to the xp network because it is not Vista
I can't download Windows Media Player 12 of third-party sites because all redirect to MS download that I can not use.
MS Windows Media Player 11 version is older than the one currently on the laptop so no improvement there.

Is it possible to add codecs to WMP11? If yes which and how?
Is it possible to legitimately ignore the GenuineCheck and another version check so that I can download the xp network?
Can anyone recommend a solution any for my original problem - to view and edit video files of me? This would bypass the need to solve this problem!

Thanks in advance.

You can install third-party codecs so that you can play and edit... In dealing with the problem with .mov files you can download klite http://www.free-codecs.com/download/QuickTime_Alternative.htmpackage., klite mega codecs that has almost all codecs except Quicktime there then go for the codecs above.

It is not possible to legitimately work around the GenuineCheck and any other version control.
Your can use a third-party software like avid to edit videos. http://en.kioskea.NET/Download/start/download-1992-avid-free-DV

the wax is another edition of http://www.debugmode.com/wax/ software

Hope this will solve your problem cos these codecs will help you play the .mov files in your Media Player

Strange AngleParam value

Anyone know if there is some way to manage an AngleParam?
I am currently divide the value of some ridiculous (about 3753600) to make it usable as degrees.
Here's the function I am it feeds (such as "rot"):
public static PF_PixelFloat rotateY (PF_FpLong red, PF_PixelFloat inVec) {}
PF_FpLong tmpX = inVec.red;
TmpZ = inVec.blue PF_FpLong;
inVec.red tmpX = * OMC (red) + tmpZ * sinf (rot);
tmpZ = inVec.blue * OMC (red) - tmpX * sinf (rot);
return inVec;
}
I thought it would be just a matter of conversion from degrees to radians, but apparently not.

Hello

angle params return a value 'Fixed '.

So if you want to convert it to float, divide or simply use the FIX_2_FLOAT macro like that.

myAngleInDegrees = FIX_2_FLOAT (params [myAngle]-> u.ad.value);

And if you need one in radians (function by using the cos and sin probably need), multiply it by PF_RAD_PER_DEGREE

See you soon,.

"Preview in browser" does not, CS6 (Mac 10.6.8)

For years, I worked in CS4 and could easily get a preview in the browser. Day at CS6 about 6 months ago and can never get the preview in the browser to work. I have not spent hours online, no chance of finding any solution - many people have posted it as a problem, but no solution yet not posted online.
When I try and 'modify the browsers list' to add browsers, they haven't added to this window. I tried to check the box "preview using temporary file", but also no luck. Nothing sticks, regardless of how many times I have select browsers.
Help is greatly appreciated. I rebooted, run onyx and disk utility. I guess there is a preference for dump will fix it - but no idea what.
Works under Mac OS 10.6.8 CS6, MacBook Pro "Core 2 Duo" 2.5 mHz. A lot fast enough.

Wow! You are a sin that helped me.

The 1st solution did not work. The other fact.

But I also tried another variant, and who has been charge browsers

in a different order. Instead of trying to load Safari first, I loaded

Firefox, Chrome and Safari.

I don't know if that makes a difference.

But problem solved!

I'll post on the other forum online where I saw this unresolved problem.

You must change this:

var pt_sage = new array();

To do this:

var pt_sage = new Array();

Better yet, change it to:

Okay, it's very different from what you asked originally, but we here are:

import flash.events.Event;
import flash.events.MouseEvent;

var xU:Number; // initial x velocity (px/frame)
var xV:Number; // final x velocity (px/frame)
var x0:Number; // initial x (px)
var x1:Number; // final x (px)
var xS:Number; // x displacement (px)
var xA:Number; // x acceleration (px/frame^2)
var yU:Number; // initial y velocity (px/frame)
var yV:Number; // final y velocity (px/frame)
var y0:Number; // initial y (px)
var y1:Number; // final y (px)
var yS:Number; // y displacement (px)
var yA:Number; // y acceleration (px/frame^2)
var t:Number; // frames so far

stage.addEventListener(MouseEvent.MOUSE_MOVE, mouseMove);
stage.addEventListener(Event.ENTER_FRAME, enterFrame);

function mouseMove(e:MouseEvent):void {
    reset(e.stageX, e.stageY);
}

function reset(targetX:Number, targetY:Number):void {
    x0 = ball.x;
    x1 = targetX;
    xS = x1 - x0;
    xU = xS/20;
    xV = 0;
    xA = (Math.pow(xV, 2) - Math.pow(xU, 2))/(-2*xS);
    y0 = ball.y;
    y1 = targetY;
    yS = y1 - y0;
    yU = yS/20;
    yV = 0;
    yA = (Math.pow(yV, 2) - Math.pow(yU, 2))/(-2*yS);
    t = -1;
}

function enterFrame(e:Event):void {
    animate();
}

function animate():void {
    t++;
    var xMove:Number = xU - t * xA;
    if(xMove*xS > 0) ball.x = ball.x + xMove;
    var yMove:Number = yU - t * yA;
    if(yMove*yS > 0) ball.y = ball.y + yMove;
}

However, essentially the same thing can be achieved with much less code using TweenLite, I'd do the same if I were you:

import flash.events.MouseEvent;
import com.greensock.TweenLite;

stage.addEventListener(MouseEvent.MOUSE_MOVE, mouseMove);

function mouseMove(e:MouseEvent):void {
    animate(e.stageX, e.stageY);
}

function animate(targetX:Number, targetY:Number):void {
    var d:Number = Math.sqrt(Math.pow(targetX - ball.x, 2) + Math.pow(targetY - ball.y, 2));
    TweenLite.to(ball, d/200, {x:targetX, y:targetY});
}

who will work on webpages when updated, but I need it to operate when a button is pressed and displayed in a text field in my pdf
I'm a total noob with javascript only to start learning today so as much help that pos will be great thanks in advance

Instead of this line:

document. Write (r_text [i]);

You need to use something like this:

this.getField("Field_name").value = r_text [i];

Or if you use it as the custom text field calculation script:

Event.Value = r_text [i];

Math.COS, Math.sin = Math.HELP
