Today I have a request to my readers. I need your help.

You see, My daughter Andrea wrote a short story for a contest about bedside stories. Writers need votes to be considered. Thus, I would appreciate very much your help by voting for her here. The name of her story is Lizzy is on her way.

Andrea is currently in fourth position, but she needs more votes to get to Number 1.
You can vote once per day per browser. You can vote from your smart phone as well.

Thanks for your support. Andrea will be very happy knowing that many of you are helping her.
And… don’t forget to tell your friends as well.

I was on vacation for a couple of weeks, but I am back.

Continuing from my last example Flex 3 Example: Drawing a path at run time with adding and deleting points capabilities, I expanded the code to allow creating polygons at run time.

To create a polygon, the previous code was enhanced with graphics.endFill(); on the RedrawPath method.

I had to include additional methods to finish the polygons, as well as a method to create the last insert anchor point when finishing a polygon and more.

Below is the application to play with. To start, click on the “Add Polygon” button and then click on the stage to add points. At any time you can move any anchor (even as you are creating a polygon) to edit your polygon or any insert anchor point (light red dots) to insert additional anchor points. To end drawing a polygon click the “END” key.

Once a polygon is created in can be fully edited. Anchor points can be moved, inserted and deleted. The code is fully commented and thus I don’t go into explaining how it works in here. If you have questions post them via comments.

Get the code here.

Expanding on my last example, Flex 3 Experiment: Drawing a path at run time with insert points, here is the same example, but in this version it is possible to delete anchor points by clicking on a black point and then hitiing the DELETE key.

Although in this example and in the previous two, the title suggests is a Flex example, all the path functionality is in a AS file, so it can be run as an Actionscript project as well. It requires Flex 3.2+, Flash CS4 or other IDE that can compile for Flash Player 10.

In this case I called this a Flex example and not an experiment, because these are not really experiments ( i am not trying to do anything new really – at least not yet).

The code is available here.

Continuing from my previous post about how to draw a curve with editable points at run time, I decided to post a new one, on how to make draw a path (with straight lines) that include points to insert additional segments. Again, this is based on the book: “Foundation ActionScript 3.0 Image Effects” by Todd Yard.

By clicking a light red point between any two black points you can bisect the segment creating a new black point for manipulation, adding another light red point and repositioning the previous moved one and the new light red points to the center of their corresponding segments.  In addition, any black point can be clicked and dragged to change the location of that point. It easier to understand by drawing a path. to do that, click on the canvas below a couple of times. Then move the black points to modify the path or the light red circles to add new segments. This requires Flash Player 10. Grab the code here.

It has been a while since my last post. I Have tons of experiments and ideas to post, but I guess I procrastinate too much.

Anyway, a couple days ago a got the book: “Foundation ActionScript 3.0 Image Effects” by Todd Yard and its great. I just finished Chapter 1, but I have so many ideas to play with that I guess it will take a while to finish the book (I sort of browsed the whole thing already though).

One of the descriptions in Chapter 1, which deals with AS3 Drawing API is about changing points in a path.You can see the example below. Click on the canvas (anywher), then click somewhere else, etc.  At any time  you can drag the points to edit the path.

Another example refers to drawing curves. In this case a curve is drawn of the stage, but the user can change the start and end point and the control point.  You can play with the curve below.

[kml_flashembed movie="http://mylinerider.com/swfs/drawingCurves.swf" height="500" width="800" /]

Then, I decided to make some changes and make something like the changing points in a path, but with the path made of curves. The result is shown below. Again, click on the stage a couple of times to draw some stuff. Now besides been able to move the points, you can move the control points (in light red).  The source code is available here

Enjoy.

That’s right. I have known about Twitter for a long time now, but I could not see the value on it. OK, I am still not sure about that. However, I decided to do some research – basically I goggled “How to Use Twitter for Marketing” and I got plenty of persuasive links (see some of them below). So, I thought, hey why not experiment a little.

Following my post from yesterday about augmented reality, what better than to link to experiments made by Seb Lee-Delisle with PV3D and FLARToolkit.

The followng video shows the awesome concept…

Papervision3D augmented reality wormhole from Plug-in Media on Vimeo

Enjoy!!

A few weeks ago I saw a post on the PaperVision3D list about augmented reality using a 3D instantiated using PaperVision3D. I didn’t know what to expect, but I follow the link to check it out. The post at Sander Wichers blog, shows a nice combination of a 3D cube (made with PV3D) that can be manipulated in the real world. Sander uses a Mammoth media server (in alpha) and an augmented reality library named ARToolKitPlus as a server plug-in.

A couple of days later a saw another experiment using also PV3D and FLARToolkit a Flash implementation of ARToolkit (is in Japanese) made by Sagoosha.

I found some other interesting work on augmented reality by a French company called Total Inmmersion, that specialized on this (commercially). They have presented at the DEMO conference in 2004 and 2007. The following video is from their 2007 presentation

You can access the DEMO 2004 presentation at: http://video.google.com/videoplay?docid=6523761027552517909

A few days ago, via the Papervision3D blog (again), I found that Sagoosha published even a cooler demo to wish all of us a Happy New Year.

And you can even interact with this one by going here. Enjoy!!

I have been thinking in doimg this upgrade for a while, but I was afraid I will break something in the blog.

Finally, today I thought: what the hell, let’s give it a try.

Actually, it was pretty easy and it seems to be working fine. Now I have to get used to the new admin interface, but it looks intuitive. I specially liked the capability to update the plug ins directly. What a time saver.

I also took the opportunity to include some additional plug ins, including the “about me” and “UsersOnline ” widgets (on the right sidebar).

I would like to find a plug in to add some sponsor ads – Flash boxes or something. I have not much traffic yet, but I can include a sponsor ad for Baloka.com to support my wife business. Hey, I guess I am promoting her site in many places in here. Well, I guess that’s fine.

A few days ago I started working on some interactive charts with Flex 3 Builder Pro, and I have been making some nice progress. In the past I did some stuff with Flex 2, but the documentation and examples weren’t that great.

Now in Flex 3, the dynamic help has more and better examples and the livedocs are quite good. The charting API, however has so many possibilities that the examples and explanations are not enough. Hence, there is a lot of work required to customize the charts the way I need them.

In a few days i will start posting some examples, so others can learn from what I have been doing and hopefully I will learn more as well for the comments and feedback for my readers (Are you outthere?)
