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?
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);

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'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 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]

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'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 movieclip and when I do 3D rotation from Transform panel, It rotates perfect, center is in the middle of image, and when I apply mc.rotationY, rotation center is in left of the image, aren't 3D rotation from Transform panel and mc.rotationY from AS same? what's up?
View 2 RepliesI'm trying to do some augmented reality projects with flartoolkit . I can now put simple 3d objects on my marker and it works fine , but I wanna give my project some events that the user can interact with. I'm trying to trace the rotation of the marker. there's a container:DisplayObject3D which my application uses to add the 3d objects , I traced this :"trace(container.rotationZ)" but it's just returning 0 . I studied another AR application's source code and it was using the rotation of it's container object without problem .and I think I should mention that I'm using the exercise file of seb lee delisle papervision3d course from [URL]. anyone has any experience with flartoolkit? the main functions of my my code is as below:

Is it possible to have the child movieclip rotate separate of the rotation properties assigned to the parent? so ultimately giving the child element it's own axis?I've customized Lee Brimelows (gotoandlearn.com) 3D carousel to spin on the x axis to make it a vertical carousel. I've also rotated that by 45 degrees on the y axis to see all the items, and wrote a snippet of code to hide the left portion of the carousel. The entire carousel is contained within the 'container' movieclip, and inside of that are my carousel items (as seen below), with the larger item being the item in focus.
On rollover of the item in focus, I want to rotate it so it faces the viewer (as seen below),basically removing the 45 degree rotation applied to the container.The problem i'm running into is when you rotate the container (changing the rotationX of the container), the axis basically rotates with it, so when i rollover the next item 'in focus', the following happens..(in the example where it appears how it want it to, the carousel is at a rotationX of 0, so it works fine)
Program A has a cannon that aims to line up with where-ever the mouse is pointing, in 360 degrees, and fires when the mouse is is clicked. Program B has an eye instead of a cannon that should in theory do similar functions when the capslock key is toggled, but instead only has a 90 degree range of motion from the Right of the eye toward the bottom (quadrant 4 only). Where did the ther 270 degrees of rotation disappear to?

i.m trying to create a 3d rotation much like the widely used carousel only the rotation i desire consist of four upright(90 degrees) movieclips resting on a slanted, 30 degree plane which rotate onEnterFrame or following a tween on a oval like path - then pause for a given number of seconds at the four movieclips positions equal in distance on the plane
function around() {
this._x = Math.cos(this.angle) * radiusX + centerX;
this._y = Math.sin(this.angle) * radiusY + centerY;
var s = this._y /(centerY+radiusY);

Why isn't there the Z, rotation X and rotation Y fields in my motion editor panel?

I am watching the tutorial on the motion editor and when he opens the motion editor to edit the Rotation X and Rotation Y values I'm in trouble.My motion editor now only shows Rotation Z but, no Rotation X or Rotation Y. What am I doing wrong?
View 1 RepliesI am trying to do a simple "pseudo 3D" rotation of a movie clip. The clip would "flip" on to the screen. I have created the effect using PaperVision3D, however, the final SWF is about 64k and my project requires a smaller file size. I tried to create the flip effect manually by creating skewed versions of the clip and tweening between them, except this doesn't work because the shape is not tweaked along the vanishing point as it should be. It looks like perhaps I could accomplish what I want to do using the MatrixTransformer but I've not had much luck so far.

I have a pointer that rotates with this code (on the MC):
Code:
onClipEvent (enterFrame) {
_rotation += 0.2;
}
This works fine but now I would like to have another pointer but with an starting angle of 60degrees. Is there an easy way to ad a starting degree or angle value on this code?
How can I control the center of rotation when manipulating CS4's 3D properties? --I mean in code, that is. I've set the 3D Center Point in the Transform Panel, and if I rotate the MovieClip in the IDE, it rotates correctly... but when I manipulate rotationY via code, that 3D Center Point is not used.
View 3 RepliesSo I've found numerous tutorials on rotating to face the mouse, and none of the rotation equations work properly for me. I made my own that worked but then it just over complicated things such as bullet direction and the likes so I want to figure out what's going wrong.
Code:
var radians:Number =Math.atan2(mouseY-ME.y,mouseX-ME.x)
var degrees:Number = (radians/Math.PI)*180;

I can rotate it, or modify>transform>rotate +/- value
but what is the manual equivilant to simply object.rotation=0;
I have a client that wants a product to rotate around its axis for a full 360 degree view of the product. The final view needs to be draggable - so a user can use their mouse to turn it left or right. I took photos of the product in 10 degree increments and created a movie clip - but I can't figure out how to get it so a user can control the view: turning the product left or right.
View 3 RepliesAs you can see in my code, I'm trying to adjust on the fly the x and y properties so that the movieclip gives the impression to rotate from its center and not from its corner at 0,0
Code:
var myclip:MovieClip = new MovieClip();
myclip.buttonMode = true;
myclip.graphics.beginFill(0);
[code]....
but it doesn't work and the clip does not rotate well
I am trying create a rotating circle with buttons/menus around the edges and this would simply rotate around, not like a 3D carousel, just basic rotation of a circle triggered by movement of the mouse on a vertical axis!I have attached a jpg example to give you an idea of what I am trying to create.Would anyone be able to direct me to some tutorial something similar as I can't seem to find anything.
View 1 Repliesi was wondering if theres a way to link the amount and direction of an objects rotation to the mouse position. I want it so if you move the mouse far to the left the object spins fast anticlockwise but if you move it to the center it stops.
View 2 RepliesI recently started creating a small banner with a cog positioned half on the canvas in constant rotation and multiple buttons placed on the cog so they spin on and off the canvas. Unfortunatey at a slow rotation something like 400 frames at 25/sec the cog jitters a lot, even more when more buttons are added.
I was wondering if there was anyway to smooth out the tween for a nice non disruptive rotation and if there is anyway to cause the cog to slow down when hovering over a button.I can make it stop completely on a roll over and start again on a roll out but I was hoping for more of a speed decrease and have never worked with altering this before.
Is there a simple AC3 code to make a object rotate? I wish for the object to rotate on the X axis (in other words, if it were a 3D object, it would look like a rotation) Is there a simple AC3 fix for this?
Also, to prevent another thread being made; I used Arial text, then I swited to David text, but no matter what I try (Save, republish, simulate download) the text stays Arial text;
I have a movieclip that rotates 180 degrees in one frame of a flash game using the following code:
my_mc.onRelease=function(){
my_mc._rotation=my_mc._rotation+180;
if(my_mc._rotation==360){
[code].....
How do you get the rotation of the marker in FLARToolKit? All that I can find is how to do it with papervision3D but since I am using Unity3 for the 3D, this is not optimal.
