Ask 3DMatrix

Hey guys,

I’m curious about the as3 3DMatrix.

Can anyone give me any explanation about what is 3dMatrix?

or any sample how to use it?

is the link above using 3d matrix, and how to make something like that?

tell me whatever you know about 3dmatrix, really want to learn more about as3.

Thanks.
