"surf" objectRotate a "surf". Can be used to adjust the mesh orientation prior
to view_xifti_surface.
rotate_surf(surf, r1 = 0, r2 = 0, r3 = 0, units = c("radians", "degrees"))The "surf" object: see is.surf.
Angle to rotate along the first, second, and third column's
axis, in units (e.g. changing r1 will change the vertex positions
in the second and third dimensions/columns, since the mesh is being rotated
with respect to the first column's axis). Default: 0.
With view_xifti_surface and other mesh rendering functions that
use rgl, these rotations seem to correspond to yaw, pitch, and
roll, respectively.
"radians" (default) or "degrees".
