When panning on a 3D channel configuration, meaning a configuration (such as 7.1.4 or ambisonics) that can represent sound coming from above and/or below, the virtual sources are disposed in the shape of spherical caps. The following figures show stereo and 4.0 sources with various Spread and Focus.

Recall that 3D positioning only takes up to 7 input channels (the channels on the plane) for panning, and drops the other ones.

On the contrary, with ambisonics, channels are not exactly assigned to groups of virtual sources, but all the spatial information is preserved. The transformation of the virtual sources (rotation, contraction) behaves the same as with standard configurations, so the diagrams below apply as well, apart from the coloring.
