class expyriment.misc.geometry.XYPoint(x=None, y=None, xy=None)

The Expyriment point class

Methods

__init__(x=None, y=None, xy=None)

Initialize a XYPoint.

Parameters :

x : numeric

y : numeric

xy : (numeric, numeric)

xy = (x,y)

Notes

use x, y values (two numberic) or the tuple xy=(x,y)

distance(p)

Parameters :

p : misc.XYPoint

movement vector

Returns :

dist : float

distance to other point p

is_inside_polygon(point_list)

Return true if point is inside a given polygon.

Parameters :

point_list : list

point list defining the polygon

Returns :

check : bool

move(v)

Parameters :

v : misc.XYPoint

movement vector

rotate(degree, rotation_centre=(0, 0))

Rotate the point counterclockwise in degree around rotation_centre.

Parameters :

degree : int

degree of rotation (default=(0, 0) )

rotation_center : (numeric, numeric)

rotation center (x, y)

x
