The 3D-grid could be a volume such as an ocean body. Every vertex may hold a
range of attributes.
CV _DiscreteGridPointCoverage
A discrete grid point coverage (class CV _ DiscreteGridPointCoverage) is a set of
regularly distributed points and their attributes. The distribution is defined in the grid
values matrix (class CV _GridValuesMatrix). A discrete grid point coverage could be
considered
a
subcase
of
the
discrete
point
coverage
(class
CV _ DiscretePointCoverage) .
