ActionScript 2.0 :: 3D Coordinates Behind A Camera?

Nov 25, 2003

I've just been playing around with the 3D tutorials,I just have a problem when a point goes *behind* the camera:if point.z < 0.It's ok if there's an MC that just becomes invisible - but if I try to draw a line to this point with the drawingAPI, the point's screen x/y coordinates are weird. I can't figure out how to modify the scaleRatio to get correct values.

Here's a code snippet:

var scaleRatio = focalLength/(focalLength + z);
screen_x = x * scaleRatio;
screen_y = y * scaleRatio;

Webcam - Detect Flash-accessible Camera Without Prompting User For Access To Camera If One Exists?

Oct 11, 2010

From a Flash object, I would like to be able to detect the presence of a webcam that the user might grant access to, without actually asking the user whether they want to grant access. This is to streamline a large application that has extra features if a webcam exists — if there is a webcam, the application will present several dialogs that lead up to the normal cam-security prompt, but if the user doesn't have the hardware, I want to skip over them altogether. Requesting access to the cam before those dialogs won't make sense to the user.

It appears not to be possible to call Camera.getCamera() without the security prompt happening. Is there a workaround? (For instance, could I, perhaps, call getCamera in a hidden Flash object and inspect its return value, or does it block until the user acknowledges the security prompt?)

Media Server :: Broadcasting From Camera Blocks Other Applications From Using The Camera?

Jun 10, 2009

I have a video capture device on a machine. I have written a windows application to capture the video from this device. While capturing, if i try to broadcast using flash it does not connect. If i'm already broadcasting and then try to capture then my windows application does not get the capture pin of the device. So, flash seems to be taking the capture pin. Is there anyway to broadcast using the preview pin on the device so that i can capture using my application. Or is there way where i can split the capture pin and give one to my app and one to the broadcaster

Actionscript 3 :: Convert Global Coordinates To Local Coordinates Of A UIComplenent In Flex Project?

Dec 19, 2011

I was trying to convert global coordinates to local coordinates of a UIComplenent in my flex project using below code using below code

var gp:Point = new Point(e.stageX,e.stageY); //global point
var lp:Point = uic.globalToLocal(gp); //local point

uic is UIComponent in which I have subclass of Sprite for drawing something I have set the sprite's mouseEnabled and mouseChildren to false to not interrupt the mouse event. above code is within uic's mousemove event where I was tracing the gp and lp gp was giving correct value and suprisingly lp was giving negetive values. when I move the move to the top left corner of uic i expect lp to be 0,0 but it is giving the -width of of uic. I broke my head for hours and ended up finding an alternate by using offsets. Infact my original code was much simpler like this which was same issue

var lp:Point = new Point(e.localX,e.localY);

I am not sure what exactly is causing this problem. the workaround had lot of issues and it creating a mess in my rest of the algorithms.Just now I found even more interesting thing (which is actually weird). for some reason I went and create a new lp2

var lp2:Point = new Point(e.localX,e.localY);

now surprisingly it was giving correct values as expected and I went back and changed the code as

var gp:Point = new Point(e.stageX,e.stageY); //global point
var lp:Point = uic.globalToLocal(gp); //local point
var lp2:Point = new Point(e.localX,e.localY);
var lp2:Point = uic.globalToLocal(gp);

now it is expected to have all the lp, lp2 and lp3 variables to be same but weiredly lp two is giving wrong value and lp2 and lp3 were giving correct. I am suspecting using the variable lp has something to do. I am not sure about that but above proves it so right now I am using lp2.

ActionScript 2.0 :: Converts 3d Coordinates To 2d Coordinates - Difference Between MoveTo And LineTo?

May 21, 2007

I was reading the 'Isometric Transformations' tutorial by Danko Kozar and I have a few questions. I understand what all the code does, but not how it does it. First of all, how does the following code work:

transforms x,y,z coordinates into Flash x coordinate
xFla = function (x, y, z) {
// cartesian coordinates[code].....

I understand that it converts 3d coordinates to 2d coordinates, but I don't understand how. What numbers whould be punched into x, y, and z to acquire certain desired effects?Also, what's the difference between moveTo and lineTo:

red line
style(1, "0xFF0000", 100);
plot(0, 0, 0);
draw(200, 0, 0);

ActionScript 3.0 :: Camera Slowing Down To 4 FPS?

Nov 27, 2008

I have a problem with the camera slowing down in my project.I thought it could be because of the complexity and memory consumtion of this work, so I created a completely new movie, typed such code:

quote:

var camera:Camera = Camera.getCamera();
var video = new Video(camera.width, camera.height);
video.attachCamera(camera);
addChild(video);

[code]....

And... this time the camera's fps stayed 25fps all the time. To be honest - I really don't know why :| I mean, I'm happy the fps stayed stabily at the level, but I don't know what to do in the mentioned, complex, project to make the fps faster. I can't just add the trace line.

ActionScript 3.0 :: Camera Don't Show Up

Aug 4, 2010

I hate when flash does that. standard code that just wont work for some reason.

Code:

var video:Video = new Video(320,240);
video.attachCamera(cam);
video.x = 20;
