This generic function creates a widget for visualizing surface data, allowing for different implementations based on the type of surface object.
Create a surfwidget to display brain surface data.
Usage
surfwidget(x, width = NULL, height = NULL, ...)
# S4 method for class 'SurfaceGeometry'

irange = NULL,
thresh = c(0, 0),
vertexColors = NULL,
alpha = 1,
curvature = NULL,
colorbar = TRUE,
colorbar_label = NULL,
layers = NULL,
config = list(),
...
)
# S4 method for class 'NeuroSurface'
surfwidget(
x,

)
# S4 method for class 'ColorMappedNeuroSurface'
surfwidget(

)
# S4 method for class 'VertexColoredNeuroSurface'
surfwidget(
x,
width = NULL,
height = NULL,
alpha = 1,

colorbar = TRUE,
colorbar_label = NULL,
layers = NULL,
config = list(),
...
)Arguments
- x
A SurfaceGeometry, NeuroSurface, ColorMappedNeuroSurface, or VertexColoredNeuroSurface object
- width
The width of the widget
- height
The height of the widget
- ...
Additional arguments for customizing the widget appearance and behavior.
- data
Optional. Numeric vector of data values for each vertex.
- cmap
Optional. Color map for data visualization.
- irange
Optional. Intensity range for data visualization.
- thresh
Optional. Threshold range for data visualization.
- vertexColors
Optional. Vector of colors for each vertex.
- alpha
Opacity of the surface (0 to 1).
- curvature
Optional numeric vector of curvature values for each vertex. If not supplied for a
SurfaceGeometryobject, it is computed viacurvature(x).- colorbar
Logical; if
TRUE(default), render a colorbar when a colormap is used.- colorbar_label
Optional character label shown alongside the colorbar.
- layers
Optional list of additional data layers to display on the surface. Each layer should be a list with elements such as
data,cmap,alpha, and optionally outline-specific parameters.- config
A list of configuration options for the surface rendering:
shininessNumeric between 0 and 100. Controls the shininess of the material. Higher values create a more polished appearance. Default is 30.
specularColorCharacter. Hex color code for the specular highlights. Default is "#111111".
flatShadingLogical scalar. If
TRUE, uses flat shading; ifFALSE, uses smooth shading. Default isFALSE.ambientLightColorCharacter. Hex color code for the ambient light. Default is "#404040".
directionalLightColorCharacter. Hex color code for the directional light. Default is "#ffffff".
directionalLightIntensityNumeric between 0 and 1. Intensity of the directional light. Default is 0.5.
Unknown elements in
configare ignored with a warning.
Details
The surfwidget function creates an interactive widget for visualizing surface data, such as brain surfaces. The specific implementation depends on the class of the object provided, allowing for customized behavior for different types of surface representations.
Examples
# \donttest{
geom <- example_surface_geometry()
surfwidget(geom)
