There are several options available to aid in learning about and discovering the
Lorenz Mask, all of which are accessed from the original screen.
Parameter values
The values of
the three parameters (b, p, and k) can be changed in two ways:
Rotation
The Mask can be viewed as it is continuously rotating. To begin the rotation
routine, press 's.' On this screen, the parameters can be changed in the same
way as before, but for one change: after the desired parameter values are entered,
the 'c' key must be pressed (to recalculate the equations with
the new values). The 'f' key resets
the Mask to the original position, and the 'r' key resets the parameter
values.
*** Be sure to press 'c' every time a new value is specified or
after the 'f' key;
otherwise the equations will not be recalculated. ***
Offsets
The x-offset and z-offset is built into this program to enable
the user to find good values for the offsets in the rotation
function. These offsets shift the mask horizontally while it is
rotating in an attempt to shift the axis of rotation.
Movie
The movie function allows the user to view the Mask as it goes through a series of
changing parameters without having to change the parameters manually. To access
the movie, press 'm.'
The initial and final values for the three parameters can be changed as before.
Press 'm' to continue. The movie cycles through each of the three parameters
separately, resetting the previous parameter before continuing on
to the next one. The
values are first increased and then decreased.
*** Final note: Because of the equations used to change the parameter values, they cannot be increased or decreased from zero just by pressing and holding down the alphabetic key on the keyboard. A number other than zero must be explicitly entered in from the keyboard first. ***
You are now ready to begin exploring the Lorenz Mask.
Enjoy!
