Text: A field of vectors.
Description: A VectorField is a drawing element that displays a vector field defined in a region of the plane or of the space. For this, it draws a given number of vectors of the field. The element automatically colors these vectors according to the values (between a minimum and a maximum) of one of the components of the field.

Configuration | ||
Data | The array with the data for the vector field. | Vector field in the plane: A
three-dimensional array [m][n][5] of type double, where m
and n indicate (usually) the number of vectors in the X and
Y axes, respectively. Each element array[i][j]
actually represents a vector. The five components of this vector are:
Vector field in the space: A four-dimensional array [m][n][p][7] of type double, where m, n and p indicate (usually) the number of vectors in the X, Y, and Z axes, respectively. Each element array[i][j][k] actually represents a vector. The seven components of this vector are:
|
Autoscale | Whether to automatically compute the extrema of the last component of the vectors. | A boolean variable or one of the constants true or false. |
Minimum | The smallest value of the last component of the vectors that will be translated into a color in the scale (Autoscale must be false). | Any constant or variable of type double or int. |
Maximum | The largest value of the last component of the vectors that will be translated into a color in the scale (Autoscale must be false). | Any constant or variable of type double or int. |
Graphical Aspect | ||
Levels | Number of different color to use in the range [Minimum, Maximum]. The colors are computed interpolating between the values for the next two properties. | Any constant or variable of type int. |
Min Color | The color to assign to the minimum value of the last component of the vectors. | An Object variable of the class java.awt.Color
or one of the predefined colors: black,
blue, cyan, darkGray, gray, green, lightGray, magenta, orange, pink,
red, white, yellow.
A color can also be specified providing its integer RGB coordinates (between 0 and 255), plus an optional transparency coordinate. The default value is decided by the system. |
Max Color | The color to assign to the maximum value of the last component of the vectors. | See the values for the Min Color property. |
Invis Level | A minimum level so that vectors with a
smaller or equal value of the last component will not be drawn. This can be useful to improve the display of vector fields with many small values. |
Cualquier constante o variable de tipo double o int. |
Zoom | A scale factor to apply to the vectors displayed. | Cualquier constante o variable de tipo double o int. |
Visible | The visibility of the element. | A boolean variable or one of the constants true or false. |
