view_surface: display a surface via with rgl

In bbuchsbaum/neurosurf: Data structures and IO for surface-based neuroimaging data

Description

display a surface via with rgl

Usage

view_surface(surfgeom, vals = NA, cmap = rainbow(256, alpha = 1),
  vert_clrs = NULL, bgcol = "lightgray", alpha = 1,
  add_normals = TRUE, thresh = NULL, irange = range(vals, na.rm =
  TRUE), specular = specular, viewpoint = c("lateral", "medial",
  "ventral", "posterior"), offset = c(0, 0, 0), zoom = 1, ...)

Arguments

surfgeom	surface geometty of type SurfaceGeometry
vals	the vector of values at each surface node in x
cmap	a color map consisting of a vector of colors in hex format (e.g. gray(n=255))
vert_clrs	optional vertex colors in hex format
bgcol	a background color or vector of colors used to shade the surface.
alpha	the foreground trasnparency, default is 1 (opaque).
add_normals	whether to add_normals
thresh	a 2-element vector indicating the lower and upper transparency thresholds.
irange	the intensity range indicating the low and high values of the color scale.
specular	seergl material3d
viewpoint	the surface viewpoint (one of: 'lateral', 'medial', 'ventral', 'posterior')
offset	translation offset
zoom	zoom factor
...	args to send to rgl::shade3d
