expyriment.misc.geometry.XYPoint¶

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

The Expyriment point class

__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)¶

Return euclidian distance to the points (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)¶

Move the point along the coodinates specified by the vector 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)
