Hello!
I'm trying to use one View3D with seperate camera and scene as a
MovieMaterial to be shown on Planes in another View3D. I tried to
figure this out several times but all i can see is just a background
of first (buffer) View3D.
Sorry for posting such a long code but it's still a bit messy. Hope
you'll forgive and help me ;) Thanks in advance
first simple custom class (just for holding Planes in linked list):
package
{
import away3d.primitives.Plane;
public class LinkedPlane extends Plane
{
public var next:LinkedPlane = null;
public function LinkedPlane()
{
super();
}
}
}
here comes the main code:
package {
import __AS3__.vec.Vector;
import away3d.cameras.*;
import away3d.containers.*;
import away3d.materials.*;
import away3d.primitives.*;
import flash.display.*;
import flash.events.*;
import flash.geom.Rectangle;
[SWF
(width='1000',height='800',frameRate='60',backgroundColor='0x000000')]
