Panorama Viewer
*FIXED!!*
Here's a really simple example, all it does is texture a sphere and rotate it depending on what the camera is doing:

You can use this for pretty much any panoramic image, just change the image url and tweak it a bit

Hi Luke,
I can't get it to work at all, but how in the world did you manage to work around the 2880 px bitmap size limit and get an 8000 pixel image to load into flash?
I really like your site,
Zephyr
Hehe, that's probably why it isn't working then!
It seems to work sometimes, but sometimes not.. You've probably just pointed out why it's being so dodgy to me so I'm going to see if I can fix it.
Thanks!

Hi,
nice job, i viewing it with a little smile in my face. I took this a few weeks ago with the COD4 360 Pictures for fun like this http://www.aisn.de/aisn/examples/PV3D_Test05.swf
I like your tutorials very well!
Thanks
Phil
Excellent demo project!
Can't seem to find the base class that is affiliated with this interaction..can someone send me that class.
Dude, you're awesome! Like you said: "It seems to work sometimes, but sometimes not..." But finally it worked. I'm gonna try to compact it a little bit to see if it works better. Man, thanks for your tutorials.
I tried it, but each frameloop I get a lookAt error?
i also get the lookat error... it comes from displayobject3d.as here:
public function lookAt( targetObject:DisplayObject3D, upAxis:Number3D=null ):void
{
position.reset( this.x, this.y, this.z );
target.reset( targetObject.x, targetObject.y, targetObject.z );
zAxis.copyFrom(target);
zAxis.minusEq(position);
zAxis.normalize();
if( zAxis.modulo > 0.1 )
{
xAxis = Number3D.cross( zAxis, upAxis || UP, xAxis );
xAxis.normalize();
yAxis = Number3D.cross( zAxis, xAxis, yAxis );
yAxis.normalize();
var look :Matrix3D = this.transform;
// scale fix for lookAt()
look.n11 = xAxis.x * _scaleX;
look.n21 = xAxis.y * _scaleX;
look.n31 = xAxis.z * _scaleX;
look.n12 = -yAxis.x * _scaleY;
look.n22 = -yAxis.y * _scaleY;
look.n32 = -yAxis.z * _scaleY;
look.n13 = zAxis.x * _scaleZ;
look.n23 = zAxis.y * _scaleZ;
look.n33 = zAxis.z * _scaleZ;
this._transformDirty = false;
this._rotationDirty = true;
}
else
{
trace("lookAt error");
}
}
i put in a 'trace(zAxis.modulo);' and it comes out as 0 any idears?
