||||
This visualization builds on the previous. Structurally the cortesian grid has |
||||
been turned into an isometric one, but this is more of an environmental change |
||||
than a behavioral one. |
||||
|
||||
Behavioral changes which were made: |
||||
|
||||
* When a live point is deciding its next spawn points, it first sorts the set of |
||||
empty adjacent points from closest-to-the-center to farthest. Then it randomly |
||||
chooses a number `n` between `0` to `N` (where `N` is the size of that sorted |
||||
set) and spawns new points in the first `n` points of the sorted set. |
||||
|
||||
* Each point is spawned with an attached color, where the color chosen is a |
||||
slightly different hue than its parent. The change is deterministic, so all |
||||
child points of the same generation have the same color. |
||||
|
||||
The second change is purely cosmetic, but does create a mesmerizing effect. The |
||||
first change alters the behavior dramatically. |
||||
|
||||
In the previous visualization the points moved around in groups aimlessly. Now |
||||
the groups are all competing for the same thing, the center, and as a result |
||||
congregate and are able to be viewed as a larger whole. |
||||
|
||||
The constant churn of the whole takes many forms, from a spiral in the center, |
||||
to waves crashing against each other, to outright chaos, to random purges of |
||||
nearly all points. Each form lasts for only a few seconds before giving way to |
||||
another. |

* @fileoverview Type-safe wrappers for unsafe DOM APIs. |
||||
* |
||||
* This file provides type-safe wrappers for DOM APIs that can result in |
||||
* cross-site scripting (XSS) vulnerabilities, if the API is supplied with |
||||
* untrusted (attacker-controlled) input. Instead of plain strings, the type |
||||
* safe wrappers consume values of types from the goog.html package whose |
||||
* contract promises that values are safe to use in the corresponding context. |
||||
* |
||||
* Hence, a program that exclusively uses the wrappers in this file (i.e., whose |
||||
* only reference to security-sensitive raw DOM APIs are in this file) is |
||||
* guaranteed to be free of XSS due to incorrect use of such DOM APIs (modulo |
||||
* correctness of code that produces values of the respective goog.html types, |
||||
* and absent code that violates type safety). |
||||
* |
||||
* For example, assigning to an element's .innerHTML property a string that is |
||||
* derived (even partially) from untrusted input typically results in an XSS |
||||
* vulnerability. The type-safe wrapper goog.html.setInnerHtml consumes a value |
||||
* of type goog.html.SafeHtml, whose contract states that using its values in a |
||||
* HTML context will not result in XSS. Hence a program that is free of direct |
||||
* assignments to any element's innerHTML property (with the exception of the |
||||
* assignment to .innerHTML in this file) is guaranteed to be free of XSS due to |
||||
* assignment of untrusted strings to the innerHTML property. |

||||
* should not be escaped before interpolation. SafeStyle's contract also |

||||
* <li>Be assigned to the style property of a DOM node. The SafeStyle string |

* should not be escaped before being assigned to the property. |

* entire style string must be escaped when used in a style attribute (if |

* this were not the case, the string could contain a matching quote that |
||||
* would escape from the style attribute). |
||||
* |
||||
* Values of this type must be composable, i.e. for any two values |
||||
* {@code style1} and {@code style2} of this type, |
||||
* {@code goog.html.SafeStyle.unwrap(style1) + |
||||
* goog.html.SafeStyle.unwrap(style2)} must itself be a value that satisfies |

||||
* {@code style} of this type, {@code goog.html.SafeStyle.unwrap(style)} must |
||||
* not end in a "property value" or "property name" context. For example, |
||||
* a value of {@code background:url("} or {@code font-} would not satisfy the |
||||

* security type contract that its value, as a string, will not cause untrusted |

* script execution (XSS) when evaluated as CSS in a browser. |
||||
* |
||||
* Instances of this type must be created via the factory method |
||||
* {@code goog.html.SafeStyleSheet.fromConstant} and not by invoking its |

* constructor. The constructor intentionally takes no parameters and the type |
||||
* is immutable; hence only a default instance corresponding to the empty string |
||||
* can be obtained via constructor invocation. |
||||
* |
||||
* A SafeStyleSheet's string representation can safely be interpolated as the |
||||
* content of a style element within HTML. The SafeStyleSheet string should |
||||
* not be escaped before interpolation. |
||||
* |
||||
* Values of this type must be composable, i.e. for any two values |
||||
* {@code styleSheet1} and {@code styleSheet2} of this type, |
||||
* {@code goog.html.SafeStyleSheet.unwrap(styleSheet1) + |

||||
|

Navigation |
||||
|

* Drag mouse to look around. You can change settings to bind |

mouse-moved instead of mouse-dragged to look around. See |

customization info below. |

|

Customization |
||||
|
||||
You can customize this middleware by providing map as |
||||
:navigation-3d option in defsketch/sketch. Map can have following |
||||
optional keys: |
||||
|
||||
:position - vector of 3 numbers, initial camera position. Default |
||||
is the same as in 'camera' function. |
||||
|
||||
:straight - vector of 3 numbers, direction you'll be looking at. |
||||
Default is [0 0 -1] (looking down). |
||||
|
||||
:up - vector of 3 numbers, 'up' direction. Default is [0 1 0]. |
||||
|
||||
:pixels-in-360 - number, mouse sensitivity. Defines how many pixels |
||||
you need to move/drag you mouse to rotate 360 degrees. |
||||
The less the number the more sensitive is mouse. |
||||
Default is 1000. |
||||
|
||||
:step-size - number, number of pixels you move on each key event (wasd). |
||||
Default is 20. |
||||
|
||||
:rotate-on - keyword, either :mouse-dragged or :mouse-moved. Specifies |
||||
on which mouse event camera should rotate. Default is |
||||
:mouse-dragged. |
||||
|
||||
|
||||
Accessing position information from sketch |
||||
|
||||
navigation-3d uses fun-mode under the hood so all position-related |
||||
information is stored in the state map. It means that you can access in |
||||
draw/update/any handler and modify it if you need to. Position |
||||
information is a map which is stored under :navigation-3d key in the |
||||
state map. Position consists of 3 values: :position, :straight and :up. |
||||
See \"Customization\" section above for more details. |

/** |
||||
* Enables navigation in 3D space. Similar to how it is done in |

* This middleware requires fun-mode. |

*
|

*
|
||||
* Navigation |
||||
*
|
||||
* * Drag mouse to look around. You can change settings to bind |
||||
* mouse-moved instead of mouse-dragged to look around. See |
||||
* customization info below. |
||||
*
|
||||
* * Keyboard: |
||||
* * w - go forward |
||||
* * s - go backward |
||||
* * a - strafe left |
||||
* * d - strafe right |
||||
* * space - go up |
||||
* * z - go down, can't bind to ctrl, limitation of Processing |
||||
*
|
||||
*
|
||||
* Customization |
||||
*
|
||||
* You can customize this middleware by providing map as |
||||
* :navigation-3d option in defsketch/sketch. Map can have following |
||||
* optional keys: |
||||
*
|
||||
* :position - vector of 3 numbers, initial camera position. Default |
||||
* is the same as in 'camera' function. |
||||
*
|
||||
* :straight - vector of 3 numbers, direction you'll be looking at. |
||||
* Default is [0 0 -1] (looking down). |
||||
*
|
||||
* :up - vector of 3 numbers, 'up' direction. Default is [0 1 0]. |
||||
*
|
||||
* :pixels-in-360 - number, mouse sensitivity. Defines how many pixels |
||||
* you need to move/drag you mouse to rotate 360 degrees. |
||||
* The less the number the more sensitive is mouse. |
||||
* Default is 1000. |
||||
*
|
||||
* :step-size - number, number of pixels you move on each key event (wasd). |
||||
* Default is 20. |
||||
*
|
||||
* :rotate-on - keyword, either :mouse-dragged or :mouse-moved. Specifies |
||||
* on which mouse event camera should rotate. Default is |
||||
* :mouse-dragged. |
||||
*
|
||||
*
|
||||
* Accessing position information from sketch |
||||
*
|
||||
* navigation-3d uses fun-mode under the hood so all position-related |
||||
* information is stored in the state map. It means that you can access in |
||||
* draw/update/any handler and modify it if you need to. Position |
||||
* information is a map which is stored under :navigation-3d key in the |
||||
* state map. Position consists of 3 values: :position, :straight and :up. |
||||
* See "Customization" section above for more details. |
||||
*
|
||||
* Usage example: |
||||
*
|
||||
* (q/defsketch my-sketch |
||||
* ... |

* :middleware [m/fun-mode m/navigation-3d]) |
