class ContactPointProposal

Bases: NamedTuple

A proposal of a contact point on an object.

Methods

count(value, /)	Return number of occurrences of value.
index(value[, start, stop])	Return first index of value.

Attributes

normal	The normal of the contact point, pointing outwards.
object_id	The identifier of the object.
point	The position of the contact point.

__add__(value, /)

Return self+value.

__getitem__(key, /)

Return self[key].

__init__()

__iter__()

Implement iter(self).

__len__()

Return len(self).

__mul__(value, /)

Return self*value.

static __new__(_cls, object_id, point, normal)

Create new instance of ContactPointProposal(object_id, point, normal)

Parameters:

• object_id (int)

• point (Tuple[float, float, float] | List[float] | ndarray)

• normal (Tuple[float, float, float] | List[float] | ndarray)

count(value, /)

Return number of occurrences of value.

index(value, start=0, stop=9223372036854775807, /)

Return first index of value.

Raises ValueError if the value is not present.

normal: Tuple[float, float, float] | List[float] | ndarray

The normal of the contact point, pointing outwards.

object_id: int

The identifier of the object.

point: Tuple[float, float, float] | List[float] | ndarray

The position of the contact point.
