The object class name (object.__class__.__name__).

getId()

Accessor to the object’s id.

Returns

idint

Internal unique identifier.

getName()

Accessor to the object’s name.

Returns

namestr

The name of the object.

getShadowedId()

Accessor to the object’s shadowed id.

Returns

idint

getSimplices()

Collection of simplex accessor.

Returns

simplicesIndicesCollection

Collection of simplices.

getVertices()

Collection of vertices accessor.

Returns

verticesSample

Collection of points.

getVisibility()

Accessor to the object’s visibility state.

Returns

visiblebool

Visibility flag.

hasName()

Test if the object is named.

Returns

hasNamebool

True if the name is not empty.

hasVisibleName()

Test if the object has a distinguishable name.

Returns

hasVisibleNamebool

True if the name is not empty and not the default one.

query(*args)

Get the index of the enclosing simplex of the given point.

Available usages:

query(point)

query(sample)

Parameters

pointsequence of float

Given point.

sample2-d sequence of float

Given points.

Returns

indexint

If point is enclosed in a simplex, return its index; otherwise return an int which is at least greater than the number of simplices.

indicesIndices

Index of enclosing simplex of each point of the sample. If there is no enclosing simplex, value is an int which is at least greater than the number of simplices.

queryScalar(point)

Parameters

xfloat

Given point.

pointsequence of float

Sequence of 1D points.

Returns

indexint

If x is inside RegularGrid bounds, return the index of the interval in which it is contained; otherwise return an int which is at least greater than the number of intervals.

indicesIndices

Index of the enclosing simplex of the given 1D points.

setName(name)

Accessor to the object’s name.

Parameters

namestr

The name of the object.
