Exemplary NetLogo Models by Ralph

Example 01, repeated dots

painting with patches using pxcor arithmetic

on "go", the jumping turtle could play notes

Example 02, sloping lines

painting with patches using pxcor and pycor arithmetic

Example 03, moving lines

painting and repainting with patches to animate the background

Example 04, musical fish

the fish plays the trumpet on encountering the moving pattern

Example 05, drawing with mouse

draws patch patterns with the mouse button pressed

Example 06, drawing with mouse

draws pixel patterns with the mouse button pressed

Example 07, translation

draws patch patterns with the mouse button pressed

and then copies a vertical strip, translated to the right

Example 08, translation

like exm07 but has a "clean" button to clear outside the unit cell

Example 09, translation

like exm08 but translates repeatedly

Example 10, translate the yellow

like exm09 but imports an image and traces on it in yellow

Example 11, translate the image

like exm10 but imports an image and translate a stip of it

Example 12, player piano (only 3 notes)

like exm04 but three notes move while score is fixed

Example 13, the dorband map family

Choose a couple of initial points and click "step" or "go"

Example 14, the dorband map family

With color, stop "go" before the attractor turns all red

two attractors and basins, diagonal separatrix

Example 14 X, the twisted dorband map family

One attractor in two pieces, virtual separatrix

Example 14 HD, the dorband map family

High Def (one pixel per patch) with three color spectrum

Example 14 HDA, the dorband map family

High Def plus six color spectrum

Example 14 HDB, the dorband map family

High Def plus color rotation option (six spectra)

Example 15, the kawakami/kobayashi map family

a two parameter (a, b) polynomial family

Example 16, the kawakami/kobayashi map family

with sliders for the domain boundaries
