View 3 RepliesMy Flash application receives B-spline data from an external application but the Flash drawing API only allows quadratic bezier curves using the Graphics#curveTo() method.Is it possible to convert a B-spline into a series of curveTo() calls?
View 1 RepliesI am struggling with an issue where I want to create a function that draws an outline of any object and I want to use this outline as curve path so I can animate objects on this path using Tweener. Like that:
Code: Select allvar path = new Array();
path.push({x:300, y:0});
path.push({x:200, y:400});

Does anyone know a decent algorithm for drawing a anti-aliased (smooth) quadratic bezier curves in a raster?
I could simply draw them as vectors and then copy the image to a raster..
Is there any clever yet freely available algorithm to draw the curve directly to the pixels? I am currently using the algorithm implemented here:[URL].. I am doing this for learning purposes and because I am hoping it would be faster than using the copy pixels from a Shape option. Here is an example showing the none-smooth bezier is faster than the regular bezier:[URL]..
What's the best way to draw cubic bezier curves programmatically in AS3? The Graphics class only seems to support quadratic curves. I want to be able to do something like:
var startPoint:Point = new Point(0, 0);
var endPoint:Point = new Point(5, 5);
var control1:Point = new Point(5, 0);
var control2:Point = new Point(0, 5);
var myBezier:Sprite = getBezier(startPoint, control1, control2, endPoint);
For a performance target, I'm planning on having ~50 of these on the stage at once.
I need to implement a drag and drop functionality, where I can define and constraint the route of the draggable object.[URL].. only that i have the paths designed and not calculated by a math function. So, in fact, as mouse moves I need to tell the object to follow the custom path/movieclip.

View 1 RepliesI have watched movies of people using the motion editor, I have read books, I have even consulted the cursory help that Adobe offers. Nothing I do generates Bezier handles that i can see, although the motion lines show evidence of bezier-liek modification. What happens seems largely random.
Just as random is the scatter of keyframes. Put a symbol on the stage. Add a motion tween, Move it to a new location: fine, it works. Bend the path, and look in motion editor: suddeenly, dozens fo keyframes. Prod them with the mouse and they distrot, but with no obvios controls. Shift moves them, Cntl deletes them, Alt does god knows what, but evokes the path edit tool from Photoshop.
The documentation on this package is extremely poor. However, self-teaching is impossible as the system is not at all intuitive. If you don't know that you are supposed to toss salt over your left shoulder whilst pushing Alt-Scroll Lock, you don't see what tehbooks describe. But they always leave out that little detail. Adobe's videos are of the same style - too smallto seeproperly, all done at a tremendous pace by a laconic individual with the teaching capabilities of a firing squad.
So: please, ayone, how doo you get the Bezier handles to appear? Where does one find a decent set of documentation? Why does Flash help keep referring to Illustrator?
I have a conundrum with a design. Imagine the new Facebook timeline with lots of chronological posts attached to it. However instead of a straight line I need to make a randomized curved line with the content placed against it like so:
The complexity comes in because as the user scrolls more posts are loaded (facebook/google images style) so the line could almost be endless.
As far as I can tell my options are:
SVG - poor support in old browsers
Flash layer - embed will be huge and cause performance issues
Canvas - again the canvas will be huge and might cause performance issues
Question: Are there any cross browser gfx libraries which could do this, preferably with support for IE7/8? Or is there a smarter way to do this which I might be overlooking?

View 6 RepliesFirst i want to say its my first post and i've been diging straight up gold from this site and i love it and everyone out there smart enough to give out solutions.So basically am writing a game and i have bezier curve that controls where an actor moves. Am using only 3 points (start, control1, end) and everything is fine.Now i want to create a bezier curve that passes through a certain point (r1) at t = 0.5 . The problem being that i have my start point, my end point and my point (r1) at t=0.5, and i need to find the control point.

View 2 Repliesi am trying to make a sort of movepath like the bezier in tweenmax:[URL] for my arcade fligth game but then without the extremely hard curving. i just need to add points and let them move in that sequence and maybe a soft smoothing. but when i create the points {x:100,y:0}{x:100,y:300}{x:300,y:300}{x:300,y:900} in bezier it just creates a real ugly way to extreme curve around (you can see it in the example on tweenmax site) and that is not what i want is there a method/libary that can move objects without overextreamly curving them?
View 4 RepliesDoes anyone know of any code examples of drawing arcs as cubic bezier curves? (Yes cubic, not quadratic.) I have 2 end points, a center point, and a radius. I suppose I would also need to define a direction as well, since it could go around clockwise or counter-clockwise.

View 2 RepliesHow can I translate bezier pen anchor and control Points into drawing API code? I would like to design my shapes by hand in flash or illustrator, but have the final application draw them on the fly via the drawing api. The only way I can think of is to create a pen tool/drawing application in flash first, and record as you draw.
View 1 RepliesI have a network graph visualization generated using Gephi containing many nodes and edges.I need to produce an animation of a camera (or moving movieclip) to "flythrough" the network along the path of the bezier curves, visiting each (not necessarily every) node at random. I've made a quick animation of what this would look like.
How can I achieve this programmatically through AS3 or Processing or using mbostock D3 javascript library on github? My attempt in AS3 so far has been to convert an SVG produced by gephi into AS3 code using Miller H. Borges Medeiros' tool then try to adapt a bezier tweening library such as Zeh Fernando's example but I'm having difficulty.Medeiros' converter is splitting quadratic beziers into 4 separate quadratic beziers, and I'm not sure how to transform flash's curveTo Method into an array of bezier points as in Fernando's code.Then there is the problem of animating the camera through only those nodes which are connected to eachother.

I am using the draw() method of the BitmapData to encode a jpeg of part of the image. Now this should be easy enough given the object I want to draw to the bitmap is on the stage at design time so I know its location and dimetions exactly! Heres the code I have in place.
Code:
var myBitmapSource:BitmapData = new BitmapData ( street.width, street.height, false, 0x333333);
myBitmapSource.draw(street, null, null, null, new Rectangle( 96, 5, 571, 450 ), true );
I know for a FACT that no part of the street clip I am drawing out is in negative space, and it's registration is (0,0). However, it cuts off A lot of the top of my image. y=5 in the above rectangle is where I need the top to be, but it cuts the top off of the image... even if I change it to 0, it has no effect.
I'm making something that requires me to draw() the youtubeplayer Giving me this pretty error:
[Code]...
I'm trying to do some lean blitting for an object that rotates by rotating it once at startup and capturing a BitmapData snapshot of each 5 degrees. The problem I'm having is that the draw() method of the BitmapData object is only picking up pixels in the MovieClip that are below and to the right of the registration point. If I change the MC so that the registration point is in the top left corner, I sometimes get what looks like most of the pixels, but the entire object rotates into and out of the frame, since it's rotating around the corner and not the center.
View 5 RepliesI need to be able to draw a thick patterend line between 2 points in AS3, I can't use the draw API because it doesn't all me to actually put detail (pattern etc) into the thickness of the line, I thought about perhaps using the line to create a bitmap version and then using that as a mask, but I remember many years ago seeing some examples that use a movieclip as a source for a line.

How do I get around this error? The main objective is to print the stage using PrintJob(). I am using Flash Professional CS5.5 and publishing to Flash 10.0/10.1. Let me know if I need to supply any more info.
i have a class thats create a class with bitmapData that merge 2 IBitmapDrawable. one of them is 24*20 while the other is 16*16.i want to draw the smaller first in a bitmapData object which its width and height are 24*20 but i want to draw it in the center of the big bounds.

i'm a novice to ActionScript but from failed Google function searches, i think i've choosen an advanced i hope possible task: how to read then apply bezier, anchor point and handle positions to different anchor points. What i need to do is precisely align a rectangular closed bezier path with a randomly shaped closed bezier path, both with the same number of anchor points.
