Methods

AddNode(data, key)

Adds a node from data into the graph
Parameters:
Name Type Description
data dictionary the data as loaded from the json file
key string the ID of the node
Source:

ApplyOperation()

The core of the shunting yard algorithm. Better not to modify.
Source:

ChangeColor(node, color)

Changes the color of a node
Parameters:
Name Type Description
node Graph.node the node that changes color
color Three.color the new color of the node
Source:

Colorize(col, indexOfProperty)

Colorizes the nodes in different shades of a certain color based on intensity of a property
Parameters:
Name Type Description
col Three.color the color in which to colorize
indexOfProperty indexOfProperty the index of the property based on which to colorize
Source:

Contains(node, word)

Evaluates if a the metadata of a node (id + categories) contains the regular expression word
Parameters:
Name Type Description
node Graph.node the node that is being evaluated
word string a regular expression
Source:

defineColorPicker2()

Creates the color picker and attaches events to it.
Source:

defineCombo(data)

Creates the combobox and populates it with properties names from the data
Parameters:
Name Type Description
data dictionary as loaded from the json file
Source:

DefinePrioritiesOfOperators()

Defines the priorities of the operators NOT, AND, OR. The higher the number, the higher the priority.
Source:

EmptyStacks()

Finishes the shunting yard algorithm. Better not to modify.
Source:

Evaluate(node, expression)

Evaluates if the metadata (id + categories) of a node satisfies the expression. Not case sensitive. Implements the 'shunting yard' algorithm
Parameters:
Name Type Description
node Graph.node the node that is evaluated
expression string the expression under which the node is evaluated. A boolean expression of regular expression. Ex: xx AND Y OR NOT zz. xx, yy, and zz are regular expressions. The presedence of the boolean operators is defined in DefinePrioritiesOfOperators().
Source:

HandleNodeHovering(node)

Defines what happens when a user hovers over a node (point)
Parameters:
Name Type Description
node Graph.node a node from the graph that was hovered over
Source:

HandleShowFoundNodesChange()

What to do when the "show found nodes" box is changed
Source:

HandleSizeAttenuationChange()

What to do when the user clicks on the size attenuation box
Source:

HasHigherPriority(operatorsStack, operator)

Evaluates if an operator has a higher priority than the top of the operatorsStack
Parameters:
Name Type Description
operatorsStack list the stack of operators as defined in the shunting yard algorithm by Dijkstra
operator string one of NOT, AND, and OR.
Source:

InitDrawing(data)

Initializes rendering frame and draws the graph in an initial scene
Parameters:
Name Type Description
data dictionary The dictionary of points as loaded from the json file
Source:

InitEventHandlers()

Initializes the check boxes and the event handlers for the checkboxes
Source:

InitGlobalDataVariables()

Initiates the global variables
Source:

InitializeGraph()

Initializes the graph
Source:

Is_operator()

Evaluates if the string word is in the list [AND, OR, NOT]
Source:

LoadAllNodes()

Loads all points from the data file in the graph
Source:

LoadDataFromFile(file)

Loads data from file and makes initializations necessary to render data points
Parameters:
Name Type Description
file file The file selected by the user
Source:

LoadDataInGraph(data)

Loads all data in the graph
Parameters:
Name Type Description
data dictionary the data as loaded from the json file
Source:

LoadLocalDataSet()

Is called when the user selects a file to upload
Source:

LoadOnlyFoundNodes()

Loads only the points that result from a search in the graph. At least 15 nodes are loaded, however.
Source:

PrepareColorZero(coords)

Prepares the initial colors of the points based on their coordinates. Optional.
Parameters:
Name Type Description
coords list The three coordinates of the point
Source:

PrepareNodeAndAddIt(data, key, colorpoint)

Takes a point from data and makes a node of the graph out of it
Parameters:
Name Type Description
data list a list of points
key string the id of the point
colorpoint string the desired color of the point
Source:

redrawInitialScene()

Redraws the graph in the initial scene. The camera is re-positioned to look at all points
Source:

redrawSameScene()

Redraws the graph in the same scene. The position of the camera will not change.
Source:

RemoveAllNodes()

Removes all nodes from the graph. The graph is empty afterwards
Source:

ReturnAllColors()

Returns the color of all nodes to their previous colors
Source:

ReturnPreviousColor()

Returns the color of a node to its previous color * @param {Graph.node} node - the node that changes color
Source:

SearchAndColorizeByExpression(expression)

Searches the nodes that are already loaded in the graph and colorizes in red those whose metadata or id satisfies the expression
Parameters:
Name Type Description
expression string a boolean expression of regular expression. Ex: xx AND Y OR NOT zz. xx, yy, and zz are regular expressions. The presedence of the boolean operators is defined in DefinePrioritiesOfOperators().
Source:

searchSequence()

Defines what happens when the user has pressed the search button
