Methods

line_collection(inplane_vec[, flip_other, …])	Returns a matplotlib line collection of the projected surface.
spanned_coordinates(inplane_vec[, flip_other])	Computes the 2D coordinates from the position

Attributes

npoints

line_collection

ProjectedMesh.line_collection(inplane_vec, flip_other=False, surface_arr=None, axes=None, **kwargs)

Returns a matplotlib line collection of the projected surface.

Parameters

• inplane_vec – (3, ) array defining the hemisphere that will be used as the x-coordinate (see ProjectedMesh.spanned_coordinates)

• flip_other – if True the y-coordinate is defined based on the negative of the cross product betwen the plane normal and inplane_vec rather than the positive

• surface_arr – (N, ) or (N, 3) array defining values for vertices on the original mesh. If set will be used to set the color along the line;

• axes – matplotlib axes. If set the LineCollection will be added to this plot

• kwargs – keywords are pased on to the creation of the LineCollection (see matplotlib.collections.LineCollection)

Returns

the new LineCollection

Return type

matplotlib.collections.LineCollection

spanned_coordinates

ProjectedMesh.spanned_coordinates(inplane_vec, flip_other=False)

Computes the 2D coordinates from the position

Parameters

• inplane_vec – (3, ) array with any in-plane hemisphere defining the first coordinate

• flip_other – if True the second coordinate is defined based on the negative of the cross product betwen the plane normal and inplane_vec rather than the positive

Returns

(Npoints, 2) array with the coordinates along and perpendicular to inplane_vec
