  Vector fields are one of the fundamental parts of mathematics which are key
for modelling many physics phenomena such as electromagnetic fields or fluid
and gas flows. Fields found in nature often exhibit complex structures which
can be difficult to analyze in full detail without a graphical representation.
In this paper we introduce FieldView -- an application targeted at academics
and industry professionals wanting to visualize vector fields using various
rendering techniques. FieldView uses a novel way of evaluation of the field and
construction of the displayed elements directly on the GPU which is based on
the recently introduced mesh shader graphics pipeline by NVIDIA. Research done
for FieldView development has found practical application in the form of
magnetic field visualisation integrated in the data processing framework
developed by ALICE experiment at CERN.
