Geometry
Arrays – This property returns an IGeometryArrays that provides access to arrays
defining the LatticeInfo object corner and annotation values.
//Get the size arrays
int [ ] sizes = lattice.Arrays.GetSizeArray();
Corners – This property returns an IGeometryCorners that provides access to the
geometry information for the four lattice corners.
//Get the X location for corner 2
double cornerX = lattice.Corners.WorldX(2);
Operations - Convenience functions to convert between world, index, and annotation
values as well as rotating the geometry. The property returns an
IGeometryOperations from which the conversions may be done.
double[ ] x = {100000.0, 100010.0, 100020.0};
double[ ] y = {200000.0, 200020.0, 200040.0};
//Convert X and Y arrays in place to indexes.
lattice.Operations.WorldToIndex(x, y);
Single – This property returns an IGeometrySingle that allows individual
LatticeInfo geometry information (origin, spacing, rotation) to be read.
//Get the LatticeInfo object I axis rotation.
double rotationI = lattice.Single.RotationI;
UnitCorners – This property returns an IGeometryUnitCorners that allows viewing
of geometry information in three points. The points represent the origin and the corners at
the end of the unit vectors along the I and J axis (1, 0) and (0, 1).
//Returns the X positions at the three corners
double[ ] x = lattice.UnitCorners.GetWorldUnitX();
LatticeInfo provides the following public methods:
Equals – This method compares two instances of LatticeInfo objects. A certain
amount of leeway is provided when the comparison is done, which amounts to 1/10 of the
4-172 Ocean Application Development Framework 2008.1
