_______________________________________
This application provides interactive
help when !Help, or !Bubblehelp, is
active.
_______________________________________
What this software does
This fully RISC-OS compliant
multitasking application allows the
entry of a 3D function (z = f(x,y)) in
BASIC format and the function to be
evaluated for a range of x and y. The
data can be displayed graphically using
either !Surface or !3DPlotter.
Note that 3DFNEdit cannot by itself
display the function graphically.
_______________________________________
Running the application
Double clicking on the !3DFnEdit icon
in a directory viewer will install its
icon on the icon bar.
Clicking SELECT on the iconbar icon at
any time will open the function entry
window if it is not already open.
_______________________________________
The Iconbar Menu
Clicking with MENU on the iconbar icon
offers the following options:
Info
The standard information box, with
version number. This is the number that
should be quoted in any communication
regarding the application.
Quit
Terminates the application.
_______________________________________
The Function Entry Window
You may enter the function in BASIC
format. The variables must be X and Y.
The function may contain over 200
characters.
It is also necessary to enter the range
of X and Y over which the function will
be evaluated, and the number of steps or
netpoints that will be used. The
evaluation and display of functions with
only 20 steps will be much faster than
with say 50 steps (the processing time
increases as the square of the steps),
but the resulting surface will be much
coarser.
_______________________________________
The Function Entry Window Menu
Clicking with MENU in the function entry
window offers the following choices.
Save
This leads to a standard "save as"
dialogue which allows the evaluated
function to be saved in text (ASCII)
format. Such saved files may be reloaded
into !3DFNEdit by drag and drop to allow
further editing. They may also be loaded
into !Surface or !3DPlotter.
Plot
!3DFNEdit will try to send the
evaluated function data directly to
!Surface or !3DPlotter for display. One
of these applications must be active for
this to work, otherwise !3DFNEdit will
complain. The function evaluation and
subsequent display requires a lot of
processing, so it may be 20 or 30
seconds before the display appears.
Explain
Opens this help window.
