My understanding of the 3D issue is that each meter in a row of meters would be slightly different. As Banned said, the light and camera stay in the same place, so the shadows on each meter would be different.

One way to do that without a lot of 3D hassle is to animate the shadow of the needle as if it were a twin to the real needle, but offset visually. In other words, the shadow is a fuzzy faint needle with the same number of frames, but it has a rotate origin that is offset down and to the side of the real needle, and is drawn "under" - before the real needle.

For each meter in the row of meters, the shadow origin would shift, and could be calculated from the audio channel number. This way, a multi-channel meter display would automatically draw appropriate shadows according to how many meters are shown. The shadow of the first needle would be to the left of the real needle, but by the 16th meter it might be to the right.

You would do the same with the shadow of the bezel surround.
