I found how to make parabola and spiral, but don't know how combine both of them and draw random fractal lines.
It is possible to draw with as3 fractal lines like in picture. Not all of them together like tree, but one by one? Any help will be appreciated.

Or do I have to get down and dirty with the math and do the spline intersection math myself? I know the basic math for Quadratic b-splines.
I'm trying to make procedural randomly generated Celtic knot-work that animates itself. I'm inspired by the book of Kells original book -and the animation of the same name. This means at best it will be seriously complicated - lots of curves animating fast. I'm going for generative -responsive to the user- Celtic knots of the highest possible complexity.... that may mean only 12 points animating randomly and in response to mouse movements but... I'd love hundreds or tens of thousands... some day.
Developing a moving random curvy double lined loop scribble was easy. I like the look of the curves made from 12 to 14 random points. Now I want to weave it over under over under. To do that -- I need to find the intersections of lots of random curves quickly for each frame. When I draw curves in Flash in the -not object- drawing mode... Flash does intersections and generates points automatically for me.
Questions:
-Is there an equivalent intersection class/method/function in Actionscript 3.0 to the intersections so easily done in the flash drawing interface?
-How much of what you do in Flash as an artist has cool classes like curveTo in Actionscript 3.0?
-Can I see the source code for curveTo?
-Can I extend the curveTo to do what I want?
-I have been reading and re-reading the reference and how to extend classes... that I made. But how to I learn how to extend curveTo ... or Path classes... can I?

We're developing a game with impactjs that allows 'chaining' of entities as they are clicked. Basically this just draws a line between the two points, with a neon glow effect. So far, so good. Now, we have a request to make the 'chain' connections animated - fire, sparkles, etc. Essentially things that seem like they'd need actual graphic animations to look right. As the entities can be any distance/angle from each other, we're stuck at how to best implement a solution for this - that is, how to draw a diagonal image, for example, between two random points that we can animate. Any thoughts our suggestions on how to pull this off would be much appreciated.
Maybe create a particle entity with an Animation Sheet containing the necessary animations/particle effects. And then draw these particles along the line that from point A to point B.
When you want to animate it to fire/sparkles etc. run the animation for all those entities. in that line.
I'd be inclined to agree with Prat. Particle effects would most likely be what you need.
Here is a tutorial on generating particle effects in impact.js that might help you out.

I am using ZedGraph to draw graphs in C#. I have been asked to draw a parabole and a "normal" line in the same graph, and I need to know programatically if the parabole and the line intersect at any point (actually, I have to know that AND if one line is close enough from the other).
Is there a way to know that in ZedGraph?
Thank you very much in advance.
I want to make a jigsaw puzzle in flash. I know how to create square kind of shapes. But I want to create this kind of irregular shapes. See the live demo of puzzles in the links shown
http://www.flashcomponents.net/component/jigsawpuzzle/preview/4952.html
http://www.gamedesign.jp/flash/whitejigsaw/whitejigsaw.html
I just want to how to create the irregular shapes.
Does anyone know or can anybody give useful links as to how this can be done.
My ideas:
Shapes can be just Bitmaps, masked by irregular filled Shape. Each piece of puzzle has shared BitmapData. Shapes can be created by series of drawRect/drawEllipse/curveTo calls in fill mode.
Watch their relative positions to catch the moment when they should 'snap' together. Also cull combinations not close to each other.
If you're creating your shapes dynamically with code, try using the graphics.curveTo() method. This can be used in combination with graphics.lineTo() to make the outline for your pieces.
You could also make your pieces using the pen tool within the Flash IDE to create movie clips that can my used for creating object instances to be used as masks for your puzzle. This works if you plan on having the same puzzle layouts more than once.
That's done using masking: http://www.flash-here.com/tutorials/flash_masking.html

Using Actionscript 3 I'm drawing multiple Shapes onto a MovieClip [top drawing]. The end result I need is the bottom drawing. I originally thought it would be simple to just merge the shapes and then find a way to draw a border around the end result but I can't seem to find any way of doing this.
Is this possible or is there a better way of trying to do this?
there are 3 ways to go:
hard math. don't draw them directly, but draw through an additional abstraction layer where calculate the resulting curves and draw them.
simple abstraction layer. instead of drawing directly, draw them twice in 2 colors, an inner and an outer one, the outer being one pixel bigger (obvious in the case of circles at least). Only works if you draw into the same Graphics object.
use a GlowFilter with no blur (try what using 1 does) and knockout set to true.
