The location of the vectors is 3D at most; missing coordinate dimensions will be padded with zero. The direction of the vectors is also 3D at most; missing data variables will be padded with zero. For example, a 1D uniform lattice with 2 data variables would have all the vector endpoints on the X axis (because the Y and Z coordinates will be padded with zero), and all the vectors will lie in the XY plane (because there are only two data variables).
Vector magnitudes are the product of data vector field lengths and a scaling factor.
This is the input lattice.
Port: Scale Factor
This is a multiplicative scaling factor applied to the vector's magnitude.
This the vector line segment geometry.
