Parameter
Here we are setting the spin of the particles in Group 1 to constant values: a Real for the Speed of rotation and a Vector for the Axis of rotation. Only particles of a certain age have been placed in Group 1.
This value represents the rotation speed, measured in change of angle per second. The value is in radians, where 2*Pi radians represents 360°. Therefore, a value of 2*Pi here will result in one complete revolution per second.
This defines the axis around which the particles rotate. For example, a value of (0;0;1) means that each particle will rotate about its Zaxis.
Outputs the spin of the particles. Connect this to the Spin port of a PSetData node to control the spin of particles.
