pointsseq¶
Sequences of Points
.

class
nutils.pointsseq.
PointsSequence
(ndims)¶ Bases:
nutils.types.Singleton
Abstract base class for a sequence of
Points
. Parameters
ndims (
int
) – The dimension of the point coordinates.
Notes
Subclasses must implement
__len__()
andget()
.
static
from_iter
(value, ndims)¶ Create a
PointsSequence
from an iterator. Parameters
 Returns
sequence
 Return type

static
uniform
(value, length)¶ Create a uniform
PointsSequence
. Parameters
 Returns
sequence
 Return type

static
empty
(ndims)¶ Create an empty
PointsSequence
. Parameters
ndims (
int
) – Returns
sequence
 Return type

npoints
¶ The total number of points in this sequence.

__bool__
(self)¶ Return
bool(self)
.

abstract
__len__
(self)¶ Return
len(self)
.

__iter__
(self)¶ Implement
iter(self)
.

__getitem__
(index: int) → Points¶ 
__getitem__
(index: Union[slice, numpy.ndarray]) → ’PointsSequence’ Return
self[index]
.

__add__
(self, other)¶ Return
self+other
.

__mul__
(other: int) → Points¶ 
__mul__
(other: ‘PointsSequence’) → ’PointsSequence’ Return
self*other
.

abstract
get
(self, index)¶ Return the points at
index
.

take
(self, indices)¶ Return a selection of this sequence.
 Parameters
indices (
numpy.ndarray
, ndim: 1, dtype: int) – The indices of points of this sequence to select. Returns
points – The sequence of selected points.
 Return type

compress
(self, mask)¶ Return a selection of this sequence.
 Parameters
mask (
numpy.ndarray
, ndim: 1, dtype: bool) – A boolean mask of points of this sequence to select. Returns
sequence – The sequence of selected points.
 Return type

repeat
(self, count)¶ Return this sequence repeated
count
times. Parameters
count (
int
) – Returns
sequence – This sequence repeated
count
times. Return type

product
(self, other)¶ Return the product of this sequence with another sequence.
 Parameters
other (
PointsSequence
) – Returns
sequence – This product sequence.
 Return type

chain
(self, other)¶ Return the chained sequence of this sequence with
other
. Parameters
other (
PointsSequence
) – Returns
sequence – The chained sequence.
 Return type

tri
¶ Triangulation of interior.
A twodimensional integer array with
ndims+1
columns, of which every row defines a simplex by mapping vertices into the list of points.

hull
¶ Triangulation of the exterior hull.
A twodimensional integer array with
ndims
columns, of which every row defines a simplex by mapping vertices into the list of points. Note that the hull often does contain internal element boundaries as the triangulations originating from separate elements are disconnected.
