Vector Rotation

Usage

rotate(x, rotaxis, rotangle)

# S3 method for class 'Vec3'
rotate(x, rotaxis, rotangle)

# S3 method for class 'Ray'
rotate(x, rotaxis, rotangle)

# S3 method for class 'Line'
rotate(x, rotaxis, rotangle)

# S3 method for class 'Plane'
rotate(x, rotaxis, rotangle)

# S3 method for class 'Pair'
rotate(x, rotaxis, rotangle)

Arguments

x

object of class "Vec3", "Line", "Ray", "Plane", "Pair", or "Fault", where the rows are the observations and the columns are the coordinates.

rotaxis

Axis of rotation given as object of class "Vec3", "Line", "Ray", or "Plane".

rotangle

Angle of rotation in radians for "Vec3" objects and in degrees for "Line", "Ray" and "Plane" objects.

Value

objects of same class as x

Examples

vec1 <- Vec3(1, 0, 0)
vec2 <- Vec3(0, 0, 1)
rotate(vec1, vec2, pi / 2)
#> Vector (Vec3) object (n = 1):

# rotate Fault data (sense of motion changes!)
