source: XIOS/trunk/src/filter/spatial_transform_filter.hpp @ 873

Last change on this file since 873 was 873, checked in by mhnguyen, 9 years ago

Masked interpolated points will have default_value (if defined)

+) Default value is used to initialize spatial transform filter
+) Add a new case for testing masked points

Test
+) On Curie
+) All interpolation tests work
