trimesh.typed module

class trimesh.typed.Any(*args, **kwargs)

Bases: object

Special type indicating an unconstrained type.

  • Any is compatible with every type.

  • Any assumed to have all methods.

  • All values assumed to be instances of Any.

Note that all the above statements are true from the point of view of static type checkers. At runtime, Any should not be used with instance checks.

class trimesh.typed.BinaryIO

Bases: IO[bytes]

Typed version of the return of open() in binary mode.

abstract write(s: bytes | bytearray) int
class trimesh.typed.Callable

Bases: object

trimesh.typed.Dict

alias of dict

class trimesh.typed.Hashable

Bases: object

class trimesh.typed.IO

Bases: Generic

Generic base class for TextIO and BinaryIO.

This is an abstract, generic version of the return of open().

NOTE: This does not distinguish between the different possible classes (text vs. binary, read vs. write vs. read/write, append-only, unbuffered). The TextIO and BinaryIO subclasses below capture the distinctions between text vs. binary, which is pervasive in the interface; however we currently do not offer a way to track the other distinctions in the type system.

class trimesh.typed.Iterable

Bases: object

trimesh.typed.List

alias of list

class trimesh.typed.Mapping

Bases: Collection

A Mapping is a generic container for associating key/value pairs.

This class provides concrete generic implementations of all methods except for __getitem__, __iter__, and __len__.

get(k[, d]) D[k] if k in D, else d.  d defaults to None.
items() a set-like object providing a view on D's items
keys() a set-like object providing a view on D's keys
values() an object providing a view on D's values
class trimesh.typed.Sequence

Bases: Reversible, Collection

All the operations on a read-only sequence.

Concrete subclasses must override __new__ or __init__, __getitem__, and __len__.

count(value) integer -- return number of occurrences of value
index(value[, start[, stop]]) integer -- return first index of value.

Raises ValueError if the value is not present.

Supporting start and stop arguments is optional, but recommended.

trimesh.typed.Set

alias of set

trimesh.typed.Tuple

alias of tuple

class trimesh.typed.float64(x=0, /)

Bases: floating, float

Double-precision floating-point number type, compatible with Python float and C double.

Character code:

'd'

Canonical name:

numpy.double

Alias on this platform (Linux x86_64):

numpy.float64: 64-bit precision floating-point number type: sign bit, 11 bits exponent, 52 bits mantissa.

as_integer_ratio()

Return a pair of integers, whose ratio is exactly equal to the original floating point number, and with a positive denominator. Raise OverflowError on infinities and a ValueError on NaNs.

>>> np.double(10.0).as_integer_ratio()
(10, 1)
>>> np.double(0.0).as_integer_ratio()
(0, 1)
>>> np.double(-.25).as_integer_ratio()
(-1, 4)
is_integer() bool

Return True if the floating point number is finite with integral value, and False otherwise.

Added in version 1.22.

Examples

>>> np.double(-2.0).is_integer()
True
>>> np.double(3.2).is_integer()
False
class trimesh.typed.int64

Bases: signedinteger

Default signed integer type, 64bit on 64bit systems and 32bit on 32bit systems.

Character code:

'l'

Canonical name:

numpy.int_

Alias on this platform (Linux x86_64):

numpy.int64: 64-bit signed integer (-9_223_372_036_854_775_808 to 9_223_372_036_854_775_807).

Alias on this platform (Linux x86_64):

numpy.intp: Signed integer large enough to fit pointer, compatible with C intptr_t.

bit_count() int

Computes the number of 1-bits in the absolute value of the input. Analogous to the builtin int.bit_count or popcount in C++.

Examples

>>> np.int64(127).bit_count()
7
>>> np.int64(-127).bit_count()
7
