GeoTransData GTD union

Declared in: GeoTransformers.h

Union of data structures encapsulated within GeoTransData I/O packages. GeoTransformers are interpreting the given address as to which of these structures it points to.

[C / C++]

union GTD {

VERTEX3D Point3D; // single 3D point

VERTEX2D Point2D; // single 2D point

ARRAY3D MPoints3D; // multiple 3D points

ARRAY2D MPoints2D; // multiple 2D points

TABLE Grid; // Grid of float Z values

} * as; // pointer to data structure
