Three-dimensional VBAP extends pair panning to position sources on loudspeaker triangles

Evidence

Three-dimensional vector base amplitude panning (3D VBAP) is a method to position virtual sources using such set-ups (Pulkki, 1997). It is formulated similarly to the pairwise panning in the previous section. However, now the gain factors are g = [gm gn gk]T, the direction vectors are 3D Cartesian vectors, and the loudspeaker vector base is Lmnk = [lm ln lk] in Figure 14. — Ville Pulkki, Matti Karjalainen, Communication Acoustics- An…, 1897
