Parameter Plane and Julia Set Applet Version History
Added check for infinity and NaN to escape criterion.
Changed from 16 decimals to 12 decimals on iter pane.
Number of orbits can now increase up to 40,000.
Fixed bug that caused the domain/ranges of dynamic and parameter plane to update improperly when changing functions.
ctrl+click means "reset center on zoom panel and do not zoom."
Added label to zoom panel.
Scientific notation on iter pane changed from "1.23E03" to "1.23 E03".
Applet title is now "Parameter Plane and Julia Set."
Uses latest formatting for iteration panes.
Change color of fixed points to purple.
Changed wording from "Delay between iterations" to "Delay between path steps."
Changed wording of "escape radius" to "escape lines" for transcendental functions.
Change representation of escape criterion from circle to lines for transcendental functions.
Deleted graph settings on menu bar
Added min iterations option for Dynamic plane
Change of font sizes
Fixed bug where borders of thumbnails were not updated properly when thumbnails were created or retored.
Menu bar added. User can save graphs or screen shots of applet with a mouse click.
Using latest versions of domain/range menus, grapher beans, and function fields.
"Default Domain" now becomes "Default View"
The "version 1.0" designation could have been given long ago. I'm just now getting around to recognizing this.
Changed label "c=" to "w=" for exponent w.
Added function z^w+c (where w can be complex valued) to drop down menu.
I fixed bug when zooming in beyond 10^(-8) cased some internal rounding errors.
Fixed bug in z^d+c/z^m function where d and m were not updated properly
I reluctantly changed the name of the Stankewitz number to "color sample rate."
I totally re-did how I was creating the thumbnails in order to cast out more thumbnail demons.
zWhen restoring a thumbnail using z^d+c or z^d+c/z^m and the thumbnail has a value for d (or m) that is inconsistent with current graphers, the current graphers are forced to be in sync with the restored thumbnail.
The user has the ability to control the Stankewitz number. This will determine how many colors of the color palette will be sampled. For example, a value of 2 means that every other color will be used. A value of 3 means that every third color will be used.
Verstion 0.93 was never released.
z^d+c/z^m has been added as a function option.
Thumnbnail demons have been exorcised (I hope).
ctrl+click when zooming puts cursor location in zoom panel "Default" fields. Otherwise, the default fields do *not* automatically change.
Thumbnails are created when zooming via mouse wheel rotation.
Inadvertent mouse drags which create very small zooming boxes no longer zoom in/out.
Critical orbit is now properly updated when changing between functions.
Critical orbits would not always start at appropriate place when toggling between functions. This has been fixed.
New color scheme (based on old one) has been implemented.
Size of some labels/buttons has been changed.
Zoom box did not disappear when using very small-sized zooms. This has been fixed.
Fixed points are now updated when restoring a thumbnail.
Fixed restore thumbnail bugs.
Added separate black/white plot options for parameter and dynamic planes
Add change in border color to most recently restored thumbnail.
Colors of zoom rectangles, critical orbit, and escape radius have all changed for black/white plots.
Decreased default orbit tolerance for determination of periodicity.
Corrected bug in period calculation.
Changed title of button to "Delete all thumbnails".
Corrected bug for calculating fixed points along a path and eliminated calculation for all but z^2+c case.
Default number of path steps in transcendental functions is 5.
Orbits 1 and 2 are now zeroed out when changing c value in Mandelbrot set.
"Get Orbit Data" buttons removed.
If current picture does not have associate thumbnail, this is now created when enlarging an existing thumbnail
"Get Orbit Data" buttons removed.
Algorithm for generating thumbnails is revised using the principle "generate a thumbnail when a a picture is changed that does not currently have a thumbnail.
Added "Remove all" button for thumbnails.
Max number of thumbnails has been increase to 30.
Border of most recently created thumbnail is colored white. This tells user which (if any) thumbnail will be eliminated with next thumbnail creation.
Orbit 1 and Orbit 2 iteration panes have been combined into one pane.
Escape radius has been converted into escape radius for dynamic plane and escape radius for parameter plane.
When switching generating functions, orbit data is now updated automatically.
To avoid accidental drag that results in a zoom, user must drag rectangle at least 2 pixels for zoom to commmence.
Revised order/color of settings panel.
Orbit data is automatically updated in iteration panes.
Fixed "update" button so that fixed points update properly.
Updating c value and then clicking on Mandelbrot set produced incorrect path. This has been fixed.
Thumbnails now appear when zooming via clicking or dragging.
Functions ce^z, c*cos(z), and c*sin(z) now work properly.
Period calculation changed and (hopefully) improved.
Calculation of critical orbit always occurs to max orbit iter. Calcuation of orbit1 and orbit 2 now only occurs when using iteration buttons.
Black/white plots option added
Added user control of max iterations for Mandelbrot set, Julia set, and orbit.
Added data panel for various orbits.
Plot of fixed points.
Fixed several bugs.
Re-wrote graphing engine some.
Zoom by dragging rectangle that maintains relative dimensions of window.
Add two additional orbits.
Zooming on julia sets is activated
Additional function options have been implemented.
Zooming by right/left click, scrolling track wheel on mouse or moving slider on zoom panel
Zoom by dragging cursor
Different color scheme
Ability to move crosshairs in Mandelbrot set via clicking on arrows.
Graph of orbits
Option to display escape radius
Option to connect orbit points
Cleaned up drop-down menu for function options. But only one option!
Generates Mandelbrot and Julia sets.
Click on Mandlebrot set and cursor moves to new spot, animating both sets as it moves.
