Vector fields are one of the fundamental parts of mathematics which are key for modeling 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.
