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

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__
(self, index)¶ Return
self[index]
.
-
__add__
(self, other)¶ Return
self+other
.
-
__mul__
(self, other)¶ 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 two-dimensional 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 two-dimensional 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.
