ActionScript 2.0 :: Plotting On A Curve - Return The X And Y Of A Point Along That Curve?

May 10, 2007

I have a curveTo an anchor point and a control point.Then I have a function that will return the x and y of a point along that curve if I give it a number as a percentage of the curve (0 to 1).It looks like this, and works perfectly..

Code:
function drawOnCurve( interval:Number, x0,y0,x1,y1,x2,y2)
{
interval = Math.max( Math.min( 1, interval ), 0 );[code]....

x0,y0 are the start point, x1,y1 the control point and x2,y2 the final anchor point.But... I want to give it a _y value instead of a percentage (interval) and it return where on the curve that would intersect.

Flash :: Function For Extrapolating Points On A Spline Curve Or Hermite Curve Similar To Keframe Interpolation?

Aug 26, 2011

I was hoping someone could help me working out some advanced data reformatting. What I'm hoping for is a function where I can input a value along with an array of key positions like so:

function remap(percentage:Number, keypoints:Array) { ...

The array would start with the minimum and end with the maximum point, with nested key points along the way. For example, I would input something like remap(0.25, [0:0,80:50,100:100] ) and the function would 'imagine' a spline curve graph from (0,0)-(100,100) with a key point of (80,50), then return the y value that is 25% along that graph.

Actionscript 3 :: Calculating The Control Point Of Curve Using A Given Point

Jan 12, 2012

I am trying to develop a Quadratic Bezier Curve using the graphics.curveTo() method. Initially when i drag mouse to draw the shape, i use start point and end point of mouse to draw the curve line. I assume control point at any position below or up to the line. An draw the curve using this control point. some what like:-

[Code]...

Now i add a tip on this curve segment. I have x and y position of tip. I want to change the curve segment by dragging tip. but now i don't have the exact control point according to tip position. If i use tip coordinate as control point it reduce the height of curve and now tip does not lie on the curve segment. What i have to do is calculate the exact control point on the basis of tip coordinate. But i failed to get this point.

ActionScript 2.0 :: Draw Curve Through 3 Points (not Control Point)

Feb 3, 2005

I'm attempting to make a curve drawing tool a bit easier to use.Rather than drawing a basic curve and then clicking on the control point to change it, I would like the user to be able to click on the curve itself to change it, much as you do in the FlashIDE.So, given start and end points, and a point on the curve, how do you determine the control point for use with the MX API?(I googled this, but found mostly info on cubic rather than quadratic curves)

I want the text to scroll from this point changing perspective along with curve. I know how to do it in AI, PS but without doing like 100 pictures of it slowly moving and putting them in flash like an old style cartoon I have no idea how to do this... Basically when someone rolls over the button I want This to come from nothing and scroll up onto the arc and stay till they roll off... I know how to do the simple button... it's designing a movie clip that does this on an arc that i cannot figure out

ActionScript 3.0 :: Fade In Along Special Curve

Nov 16, 2010

I use Loader class to load a picture,such as example.jpg,and I know if I want to realize fade in effect,I can use following code in Event.ENTER_FRAME:sprite.alpha+=0.05.When I run above code,I can get a fade in effect of example.jpg. But the fade in effect is for the whole example.jpg, now I want to fade in the example.jpg with a special curve,such as number 9,the example.jpg fade in along number 9 curve. I guess it shoud have a mathematical model can realize this special fade in effect,anyone could give me the model of fade in along special curve?

Graph Flex LineSeries / Find Y-value Along Curve

Feb 27, 2010

I've created a Flex LineChart that shows high and low tide predictions over time. I'm using the LineSeries with form="curve", which produces a nice sinusoidal wave graph, representing water level over time. The X-axis represents time, and the Y-axis represents water level. The only data points I have to work with are high and low tide values, but I would like to figure out how to determine the y-values of arbitrary x-values along the line.[code]

ActionScript 2.0 :: Mathematics - Determine The Formula Of The Curve?

Jun 30, 2004

I can't pinpoint or make up a set of calculus to determine the right formula which describes a curve that goes through 3 specific points...I'll try to say it with a more hand-on approach. I have a spaceship which can move vertically,located to the left.The enemies, obviously, arrive from the right. Now, when i click anywhere on the scene,I want a missile/plasma orb/projectile to be shot from the spaceship, but doing more than going in a straight line: imagine 3 points, one at the spaceship, one in front (therefore to the right) of the spaceship (5/10 units in front) and the third at the click location. How do I determine the formula of the curve that goes along these three points?
