NIMLSurfaceDataMetaInfo-class | R Documentation |
This class contains meta information for surface-based data for the NIML data format
data
the numeric data matrix of surface values (rows = nodes, columns=surface vectors)
node_indices
the indices of the nodes for mapping to associated surface geometry.
