Creating the First Speaker

The sOnic Radar composition was created when you imported the sOnic file as a Composition with cropped layers. It contains eight layers that create what appears to be a solid white circle, which is actually a stack of stroked and unfilled circles. You'll position these circles in 3D space to add depth and create a virtual speaker.

The original Illustrator file's dimensions are only 111x113, so your first task is to enlarge the composition:


Open the sOnic Radar Comp 1 composition, and change its settings (Composition > Composition Settings) to use the NTSC D1 Square Pix, 720x540 preset, with Duration 1;16.


Select all the circle layers, and turn on their 3D switches in the Timeline.


With all the circle layers still selected, press the P key to display their Position properties. Deselect the layers.


Starting with the circle 2 layer, set each layer's Z value -5 degrees away from the previous layer. As a result, the Z-axis value of circle 1 is 0, the value for circle 2 is -5, the value for circle 3 is -10, and so on.

Save the composition. Duplicate the sOnic Radar Comp in the Project window, and rename one Still Radar and the other Radar Pulse.
