This is an interactive parametric graph tool/playground where you can play with the variables to get really interesting results.
This sketch was made using Processing 3, and can be run by downloading the file depthparametric.pde.
None of the examples where digitaly altered, apart from cropping them to make this montage.
| Variable Name | Function | Key |
|---|---|---|
| frq | frequency multiplier | mouseX |
| r | initial main radius | mouseY |
| amp | amplitud multiplier | q-e |
| xmax | horizontal width divider | a-d |
| N | number of lines | w-s |
| yoffset | vertical offset | up/down arrow |
| xoffset | horizontal offset | right/left arrow |
| xfade | horizontal fade flag | x |
| yfade | vertical fade flag | y |
| finfo | information panel flag | i |
| saveScaleF | save img scale multiplier | |
| save image | p | |
| ft(1-2-3) | add/rem function | 1-2-3 |
When saving an image, the program will freeze for 5 seconds or so, depending on your computer and the saveScaleFactor currently set to x4. Also, the info panel on the top right will NOT appear on the saved image, so it is not necessary to turn it off.
Most of the examples where made using the Sine parametric equation, but there's also the option to turn on and off Cosine and Circle equations, as well as other options in the code.
The radius and vertical transparency of each subsequent line is defined by nr = 5*r/(abs(n)+5.0) and yalpha = 100/(abs(n)+0.4), both dependent only on the line number.
Horizontal transparency is calculated with the dist function on xalpha = map( dist(abs(t), 0, width/scale, 0), 0, width/scale, 0, 1), and multiplies the yalpha.
Sine parametric equation is defined by x = t; y = amp*sin(t/frq).
Xmax is the width divider with limits the amount of circles for each frame according to width/xmax and to t+=frq/10; meaning, high frequency results in less circles and low frequency results in the opposite.
