`bezier`

creates 3-point Bezier-curves using the
Bernstein approximation to simulate continuous competition
in mouse- and hand-trajectories.

bezier(x = c(0, 1, -1), y = c(0, 1.5, 1.5), w = 1, resol = 100)

## Arguments

x |
a numeric vector giving the x-coordinates of exactly three
Bezier-points. Defaults to c(0,1,-1) matching the 'mt' format in
mt_align. |

y |
a numeric vector giving the x-coordinates of exactly three
Bezier-points. Defaults to c(0,1.5,1.5) matching the 'mt' format in
mt_align. |

w |
a numeric value or vector specifying one or several Bezier curves,
with `w` governing the pull towards the middle point. Each entry in
`w` creates one Bezier-curve. |

resol |
a numeric value specifying the spatial resolution of the bezier
curves. For example, `resol = 100` creates bezier curves comprised of
100 points each. |

## Value

A trajectory array containing the bezier curves.
