Line-segment geometry for drawing connections or paths in the
three-brain viewer. Vertices may be static numeric coordinates or
dynamic electrode references resolved at render time.
Public fields
typeGeometry type string ("linesegments").
colorCSS hex color string(s) applied to line segments.
sizeLine width(s) in world-space units.
verticesVertex positions: a numeric matrix (3 x N) for static
segments, or a list of position/electrode descriptors for dynamic
segments.
Active bindings
dynamicLogical; TRUE when vertices are electrode
references resolved at render time rather than static coordinates.
Methods
Inherited methods
LineSegmentsGeom$new()
Create a new line-segment geometry.
Arguments
nameUnique character name.
dynamicLogical; when TRUE vertices are electrode
references resolved at render time rather than fixed coordinates.
...Additional arguments forwarded to AbstractGeom.
LineSegmentsGeom$set_vertices()
Set vertex positions for the line segments.
Usage
LineSegmentsGeom$set_vertices(..., .list = list(), append = FALSE)
Arguments
...Positions as numeric vectors of length 3 (static mode) or
named lists with subject_code and electrode elements
(dynamic mode).
.listAdditional positions supplied as a list.
appendLogical; when TRUE append rather than replace.
LineSegmentsGeom$set_color()
Set the color(s) of the line segments.
Usage
LineSegmentsGeom$set_color(...)
Arguments
...One or more R color values (names, hex strings, or integer
palette indices) that are interpolated across all segments.
LineSegmentsGeom$set_size()
Set the line width(s).
Usage
LineSegmentsGeom$set_size(...)
Arguments
...One or more positive numbers interpolated across all
segments.
LineSegmentsGeom$to_list()
Serialize the line-segment geometry to a named list for
JSON export.
Usage
LineSegmentsGeom$to_list()
LineSegmentsGeom$clone()
The objects of this class are cloneable with this method.
Usage
LineSegmentsGeom$clone(deep = FALSE)
Arguments
deepWhether to make a deep clone.
