Spangler Applet v0.02
version 0.02
It makes very complex shapes.
I hope you like it.
Getting Started
- Make sure your mouse is in the applet region of the browser window.
- Click on the applet region to select the applet for input.
- Look at the status line in the bottom left corner of the browser window.
- Click on the applet until the status line at the bottom indicates 'running'
- Press the arrow keys to change the sequence of numbers which
constitute the formula for the Spangler.
The Keys
- left and right arrow keys move the 'cursor' among the numbers in the 'spangleSpec'
- up and down arrow keys increment and decrement the number to the left of the cursor
- moving the cursor to the right of the rightmost value adds a new number to the sequence
- pressing backspace or delete removes the number to the left of the cursor
- pressing the enter key identifies the current number as the one to perform coloring on
- B turns on buffering
- b turns off buffering
- space toggles between suspend and run
- clicking on the applet also toggles between suspend and run
What is going on?
Spangler displays number sequences (for example 2,6,5,4,3) in a fashion that can be described in english as "Draw 3 groups of 4 groups of 5 groups of figures with 6 vertices where the lines go a distance of 2 vertices."
Currently the limit on the length of sequences is 20.
What is next?
A more user friendly version is in the works. It has features like:
- a proper GUI interface in addition to the handy keyboard controls
- improved redraw logic
- threshhold detection so that lines shorter than 1 pixel are not drawn
- animation abilities
- 'moving window' support
- PostScript generation
