public class DataInputObject

extends BaseObject

Field Summary

int	height
double	t
double	tstore
double[][][]	velocityField
int	width

Constructor Summary

DataInputObject(int width, int height)
This is the object that both reads in the data array and then interpolates between values in the array to produce a field B(x,t) for the DLIC program.

Method Summary

Vec3	Bfield(Vec3 x, Vec3 B) The method that returns the input velocity array evalutated at a position x on the screen.
Vec3	Efield(Vec3 x, Vec3 E) The method that returns the E field.
double[][][]	GetArray(int width, int height) This method needs to be replaced with a method that reads in a data array of velocities, one data array for each frame in the simulation.

Constructor Detail

DataInputObject

public DataInputObject(int width,
                       int height)

This is the object that both reads in the data array and then interpolates between values in the array to produce a field B(x,t) for the DLIC program.

Parameters:

width - The width of the array

height - The height of the array

Method Detail

Efield

public Vec3 Efield(Vec3 x,
                   Vec3 E)

The method that returns the E field. For the fluid flow purposes here, this is always zero.

Specified by:

Efield in class BaseObject

Parameters:

x - the position of the observer

E - the electric field at the observer's position

Returns:

E the electric field at the observer's position

Bfield

public Vec3 Bfield(Vec3 x,
                   Vec3 B)

The method that returns the input velocity array evalutated at a position x on the screen. This method checks the time and if the time is different from the last time it inputs a new velocity array for the new time by invoking GetArray.

Specified by:

Bfield in class BaseObject

Parameters:

B - the magnetic field at the observer's position

Returns:

B the magnetic field at the observer's position

GetArray

public double[][][] GetArray(int width,
                             int height)

This method needs to be replaced with a method that reads in a data array of velocities, one data array for each frame in the simulation. To test the interface we make up the array values with a for loop.
