compute a 4x4 Transformation matrix for rotation around an arbitrary axis
compute a 4x4 Transformation matrix for rotation around an arbitrary axis
getTrafoRotaxis(pt1, pt2, theta)
pt1 |
numeric vector of length 3, defining first point on the rotation axis. |
pt2 |
numeric vector of length 3, defining second point on the rotation axis. |
theta |
angle to rotate in radians. With pt1 being the viewpoint, the rotation is counterclockwise. |
the resulting matrix can be used in applyTransform
