[Papervision3D] rotation without skew

[Felix Turner]

Hi Andrei,
 
> I followed your advice with the camera and the displayobject3d, but now,
the planes inside it no longer have focus. When I try to add events to them
i get an error.
 
AFAIK this is a bug in PaperVision: 3D Objects that are children of other 3D
Objects do not fire mouse events.
(http://osflash.org/pipermail/papervision3d_osflash.org/2007-May/thread.html
#6156). Next time I get some free time I'm going to try to find a solution.
My work around was to use away3D instead.

Hi Felix 
I followed your advice with the camera and the displayobject3d, but now, the
planes inside it no longer have focus. When I try to add events to them i
get an error. Is there something I missed?

//
for (var i:Number=0;i<52;i++) {
var material:InteractiveMovieMaterial = new InteractiveMovieMaterial(new
Letter(letters[i]), true,true);
material.animated = true;
material.smooth = true;
material.oneSide=true;
//
var plane:Plane=new Plane(material,Width,Height);
god.addChild(plane,'plane'+i);
plane.x=Math.random()*1000-500;
plane.y=Math.random()*1000-500;
plane.z=Math.random()*1000-500;
plane.rotationX=Math.random()*360;
TweenLite.to(plane,1,{x:sx,y:sy,z:sz,rotationX:0});
//
if (plane.container!=null) {
var movieSprite:Sprite=plane.container;
movieSprite.addEventListener(MouseEvent.MOUSE_OVER, rollOver);
movieSprite.addEventListener(MouseEvent.MOUSE_OUT, rollOut);
movieSprite.addEventListener(MouseEvent.MOUSE_DOWN, press);
} else {
trace('no container for '+i);
}
//
if (i>=26) {
plane.rotationY=180;
} else {
plane.rotationY=0;
}
planes[i]=plane;
sx+=Width+spacing;
if (i==25) {
sx=-4.5*(Width+spacing);
sy=Width+spacing;
}
if ((i==9) || (i==35)) {
sx=-4*(Width+spacing);
sy-=(Width+spacing)
}
if ((i==18) || (i==44)) {
sx=-3.5*(Width+spacing);
sy-=(Width+spacing);
}
}

//

Thanks again, 
Andrei

Hi,

for tiltviewer I created 1 DisplayObject3D for the grid, then set the images
to be children of the grid. The rotationX and rotationY of the grid object
are set based on the stage mouseX and mouseY. To reduce the perspective skew
on the grid, try setting the cameraZ to be -1000 (or similar) and set your
objects to be bigger, like Carlos said.

Hi Andrei

I'm 75% sure that it's all a matter of playing with the camera z and camera
focus values.
What I usually do is I connect camera z to up/down keystrokes and camera
focus to right/left; When a setting with little distortion is achieved, I
trace the values and then use them as fixed in the app...

Hi all
I already asked about this and tried the solutions you all suggested:
I want to do a rotation on x and y axes but without the skew of the 
object. My target effect would be http://www.airtightinteractive.com/
projects/tiltviewer/app/
Instead all I get is www.rossino.it/preview.html

I have a displayobject3d ( god ) where I add all my other objects
(planes) and I do the rotation on x and y of god based on the mouseX, 
respectively, mouseY.
god is at 0,0,0 and the "g plane" is in the center of the stage.

Any idea?
