pylbm.elements.Parallelogram¶

class pylbm.elements.Parallelogram(point, vecta, vectb, label=0, isfluid=False)¶

Class Parallelogram

Parameters:

pointlist

the coordinates of the first point of the parallelogram

vectalist

the coordinates of the first vector

vectblist

the coordinates of the second vector

labellist

four integers (default [0, 0, 0, 0])

isfluidboolean

• True if the parallelogram is added

• False if the parallelogram is deleted

Examples

the square [0,1]x[0,1]

>>> point = [0., 0.]
>>> vecta = [1., 0.]
>>> vectb = [0., 1.]
>>> Parallelogram(point, vecta, vectb)

Methods

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