Use Compression: grid contracts and expands Spin Mode: amount of rotation relative to compression. negative values: faster compression positive values: faster rotation Kernel Angle: Amount of rotation (0=no rotation) <x> Formula: x rotation around x axis y rotation around y axis z rotation around z axis There are two modes: 1. With brackets <> (see SpinLab doc!) < rotation around y > rotation around -y between brackets, use x and z. Examples: <x>, <z>, <xz> The rotations are in sequence: <xz> y, then x, then z, then -y All combinations are "valid" and don't break the "grid" 2. Without brackets Combination of xyz Back and forth "twist" around specified axis
