I have a similar issue, but in 4.0.  I was thinking that if I could get the screen coordinates of my mesh, I could create a flash sprite, and have it added as a child of a Flex 4 container.  I can’t seem to translate the coordinates to screen, though.  I used to use something like:

var _screenVertex:Vector3D
_screenVertex= cam.screen(_sphere,_sphere.vertices[0]);

But I can’t figure it out now.  I did create a bitmapmaterial, with textfield embedded, but the surrounding material gets in the way.  If I could alpha 0, the material, but not the text, it would work.  But right now, it blocks some of my sphere meshes.  (4.0 is awesome, by the way.  Great job!)

Thanks.

I moved your question to a separate thread.

Are you sure you are using the latest (or even a very recent) version of Away3D 4.0? There is no BitmapData, no “vertices” property and no Camera3D.screen() method in Away3D 4.0.

What you can do though is use Camera3D.project() to project the top left corner (and if you need scale, bottom right as well) of your plane and then use that to position your regular TextField in the display list.

Camera3D.project() worked perfectly for what I needed.  Thanks for your help!

Hi
Can you please post a snippet of your solution? Thanks
