Methods

"setRΘ"(p_r, p_φ)

Sets both polar coordinate attributes r and φ of this vector simultaneously.

Parameters:

Name	Type	Description
p_r	Number	The length of this vector.
p_φ	Number	The angle (w.r.t the x-axis) of this vector.

$wk$­(p_modules, p_environment_i, p_sandbox, p_annotations)

The sandbox pattern: When this function is evaluated, it first loads all modules stated in p_modules and then calls the callback function passed as last argument:

function(p_wk, p_env_1, ... p_env_n)
      { // code running in a sandbox 
      }

Parameters:

Name	Type	Argument	Description
p_modules	Array.<String> | Array	<optional>	A module name or a list of module names. A module name is a string "p1.p2.p3.M", consiting of zero ore more package/subpackage names p_i and the module name M proper. If M === "*", all modules within the package are loaded. If M === "**", all modules within the package and all subpackages, subsubpackages etc. are loaded.
p_environment_i	Object	<optional>	Zero or more environments objects, where the content of the modules are stored.
p_sandbox	function	<optional>	The sandbox, a callback function: function(p_wk, p_env_1, ... p_env_n){ ...} pwk is an instance of $wk$. The environment object contain the p_modules loaded. If there are more modules stated than environment objects, the last environment object contains the surplus modules. If no environment objects are passed, all modules are stored within p_wk.
p_annotations	String | Array | Object		Annotations that control the behaviour of the code executed within the sandbox. Plaes note: An annotation object may only be stated, if p_sandbox has been stated. Otherwise an object is interpreted as environment object.

addReplace(p_v, p_s) → {WKcVector2D}

Modifies this vector by adding another vector p_v multiplied by a scalar factor to it.

Parameters:

Name	Type	Argument	Default	Description
p_v	WKcVector2D			The vector to be added.
p_s	Number	<optional>	1	The scalar factor.

Source:

• math/geo2d/WKcVector2D.js, line 242

Returns:

this

Type

WKcVector2D

normalReplace() → {WKcVector2D}

Replaces this vector by a vector that is rotated 90 degrees counterclockwise. The length is preserved.

Source:

• math/geo2d/WKcVector2D.js, line 309

Returns:

this

Type

WKcVector2D

projReplace(p_v) → {WKcVector2D}

Replaces this vector by a projection of this vector onto another vector p_v.

Parameters:

Name	Type	Description
p_v	WKcVector2D	The vector onto which this vector is projected.

Source:

• math/geo2d/WKcVector2D.js, line 329

Returns:

this, which now is a multiple of p_v.

Type

WKcVector2D

reflectReplace(p_m, p_s) → {WKcVector2D}

Replaces this vector by the reflection vector that arises from this vector being reflected by a "mirror" vector v_m. The length of the reflection vector is the same as the length of this vector multiplied by a scalar factor.

Parameters:

Name	Type	Argument	Default	Description
p_m	WKcVector2D			The mirror vector.
p_s	Number	<optional>	1	The scalar factor.

Source:
