=== Integration-based method ===

It is the [[Integral|integration]]-based method (technique). More precisely it is based on the discrete [[Line integral|line integral]] on [[Regular grid|uniform grids]]. Discrete numerical integration is performed along a line ( more precisely curve). Line here means [[field line]] of vector field.

===Global method===

Line 118:

Applications:

* representing vector fields by aproximation a [[field line]]s of the input vector field
