If you mean 3D modeling, I don’t believe you will see that in After Effects beyond what’s in CS4 for 3D Photoshop layers.
I’m curious, what are you lacking in AE that prevents you from accomplishing your tron grid? You can rotate and position layers in 3D space. Aside from the light cycles which would have to be 3-D models, that entire scene is re-creatable in AE.
