Method Detail

getAngularDistance

double getAngularDistance(Vector3D direction)

Computes the angular distance between a vector and the border of the field. The result is positive if the direction is in the field, negative otherwise. For some of the fields (ComplexField), that value can be approximative : see particular javadoc of each class.

Parameters:

direction - the direction vector

Returns:

the angular distance

isInTheField

boolean isInTheField(Vector3D direction)

Parameters:

direction - a direction vector

Returns:

true if the direction is in the field

getName

String getName()

Returns:

the name of the field
