ActionScript 3.0 :: Rotating With Matrix3D Around A "camera"
Nov 4, 2009
I'm trying to make a "room" in flash in which you can "move" around in. I set up the room with flash cs4 3d functionality. SWF:[URL] Problem: Rotation of the camera moves the room along X and Y axis.
1. I want to make the big yellow circle in the middle to acctually look like it is in the middle of the green rotating spheres... So it is sort of the sun and the rest are the planets... This obviously has something to do with swapDepths, but I am not to good at AS and I can't figure out how to do it!
2. I wish to make the green spheres each a seperate button, so that when you click one of them it falls from the group and the camera follows it (the camera, when following its fall, should also center it)... Then the sphere will bounce on an invisible surface (invisible surface is notable by the shadow created below the ball), come to a rest in the center of the page and then the info shows up...
I am capturing camera on flex for android using air 3.1,and found that the camera is only showing the a part of of actual camera video.When i view camera using normal camera application in android galaxy tab, it shows full camera area but when i am capturing the camera in flex its showing only the center area for it.I tried using setMode to set the resolution, but its not of any use.Is there any way to get full camera area captured inside flex using camera.getCamera ?
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?)
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
I'm assigning raw matrix values through Matrix3D.rawData.When assigning certain matrices it yields the following error:
ArgumentError: Error #2188: Invalid raw matrix. Matrix must be invertible.
However, I believe the matrix data I'm passing represent an invertible matrix!Is this a (known) bug? Or is the matrix not invertible and is my math failing me?
I am trying to rotate a Sprite in three dimensions around its centerpoint, and I am struggling to understand some of the behavior of matrix3D.
Ive overridden the set rotationX, rotationY, and rotationZ methods of the Sprite as follows:
override public function set rotationX (_rotationX:Number) : void { this.transform.matrix3D.prependTranslation(this.width/2.0, this.height/2.0, 0); this.transform.matrix3D.prependRotation(-this.rotationX, Vector3D.X_AXIS);
[Code].....
I am using prependTranslation to correct the centerpoint of the rotation, and the first prependRotation to cancel out any previously-applied rotation.
Testing it out, rotationX works exactly as expected, and the Sprite rotates around its horizontal axis.
rotationY and rotationZ also appear to work fine. However, there is one problem: whenever rotationY or rotationZ are set, all of the other rotation values change as well. This is not a problem with rotationX -- if I set rotationX, nothing else changes. But if I set rotationY or rotationZ all the rotation values change, which is a problem for my app (which is trying to save and restore values).
I think I am just lacking some understanding about what is going on with matrix3D. How can I implement this so there is no interdependence between the values?
Usually Adobe Flash applications can access any usb-webcam.I have a USB camera for microscopes which understands TWAIN and DirectShow.Is there a possibility to access the video data from this camera with flash?
I am trying to experiment with new CS4 and AS3 to create 3D aplications using matrix3D class.i recently encountered a problem in the Code and I am unable to compile it even. URL:[URL]
Error Notification in FLA: 1119: Access of possibly undefined property XAXIS through a reference with static type Class.
I have a simple 3D tween that I created to 3D rotate a bitmap logo (in a movieclip) on it's x axis. It works great during testing but I noticed that when I tested it on the website that the pivot point was totally off! I had to use the matrix.prependTranslation() method to alter the pivot point so that the clip would rotate & remain centered. This is totally broken when I run in the browser but works great outside of the browser?
I'm studying John Lindquist's example from here: [URL] I'm trying to figure out how to add restrict his matrix3d method, so the sphere has limited movement.
Code: Select all override protected function onRenderTick(event:Event=null):void { var currentMousePoint:Point = new Point(viewport.containerSprite.mouseX, viewport.containerSprite.mouseY); if(isMouseDown) { var difference:Point = currentMousePoint.subtract(previousMousePoint); [Code] .....
I made a cube with as3. I wanted it to rotate in the Y Axis according to the horizontal mouse movement. It works nice when this is all I want. But if I try to also make it rotate on the X axis with the vertical mouse movement, things get screwy.
This happens because the transformations are added in the global coordinates, not the local ones. So, for Example, if I wanted the cube to rotate 30 degrees along its Y axis, I have to find a way to translate that into the global coordinates, and then apply that to the matrix3D of each face. I need a local to global translator.
I've created a game in Flash and I'm using Matrix3D and Vector3D. It works perfectly locally, but as soon as I put it on a server, the graphics don't render and I only see a thin line where a sphere should be.
I've done all the imports, but nothing seems to get it working!
I have a rotating menu that sets the selected button to the 3:00 position once clicked. I need the labels for the buttons to stay in the upright position as they rotate with the button. I have attached an image. Anyone know of an action script that would keep the labels upright?
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.
in flashplayer 11,2,202,228, attach camera to video and see local video, sometimes camera movie is freezed when I change Camera.setquality and Camera.setmode. it's not happen older flashplayer. I heard it waste memory in flashplayer 11,2,202,228,
I hate when flash does that. standard code that just wont work for some reason.
Code: var cam:Camera = Camera.getCamera(); var video:Video = new Video(320,240); video.attachCamera(cam); video.x = 20; video.y = 20; addChild(video);
I am on macbook pro and my camera doesnt show on the stage. I had a video object there named 'video' i also at some point had the imports for Camera and Video, still no luck. What am I doing wrong. I am sure I had this at some point in the past.
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;
i have a big set for a new animation im doing but i only want to view one part of it at once and have some sort of camera panning effect going round my stage. is there a plug in or somthing for this. i have looked everywere. I know it can be done as i have seen it before

if you have tried it you know that it is not working. The main thing is that on Android 2.2 the camera allowance dialog is not being displayed when you try to access it from the web browser. I've found something called PhoneGap, but it is not working on the android 2.2, or at least some parts of it is not working. Has anyone any clues how to access the camera from the web browser on Android 2.2?
