pylbm.elements.Ellipse¶

class pylbm.elements.Ellipse(center, v1, v2, label=0, isfluid=False)¶

Class Ellipse

Parameters:

centerlist

the two coordinates of the center

v1list

a vector

v2list

a second vector (v1 and v2 have to be othogonal)

labellist

one integer (default [0])

isfluidboolean

• True if the ellipse is added

• False if the ellipse is deleted

Examples

the ellipse centered in (0, 0) with v1=[2,0], v2=[0,1]

>>> center = [0., 0.]
>>> v1 = [2., 0.]
>>> v2 = [0., 1.]
>>> Ellipse(center, v1, v2)

Methods

distance(grid, v[, dmax, normal])	Compute the distance in the v direction between the ellipse and the points defined by (x, y).
get_bounds()	Get the bounds of the ellipse.
point_inside(grid)	return a boolean array which defines if a point is inside or outside of the ellipse.
test_label()	test if the number of labels is equal to the number of bounds.
visualize(viewer, color[, viewlabel, scale, ...])	visualize the element
