\section{Results}
+To prove VSL viability for using it as an alternative to another format that
+uses analytic curves called IGES~\cite{smith1983iges}, we measured
+triangulation performance and measured how many vertices and faces are
+generated when analytic curves and surfaces are transformed into them. We do
+not have the same ship hulls in both formats, so we resorted to measuring
+performance relative to vertex and face count. To work with IGES format
+we use OpenCASCADE library~\cite{opencascade}.
