pyvista_js.PolyDataReader

class pyvista_js.PolyDataReader(path: str | Path)

ベースクラス: object

Reader for legacy VTK PolyData files (.vtk).

Reads a legacy VTK ASCII file and produces a Mesh that delegates parsing to vtk.js's vtkPolyDataReader at render time. Python extracts only the point coordinates so that camera framing and bounding-sphere queries work before rendering.

パラメータ:

path (str or Path) -- Path to the .vtk file.

サンプル

>>> import pyvista_js as pv
>>> reader = pv.PolyDataReader("sphere.vtk")
>>> mesh = reader.read()

__init__(path: str | Path) → None

Initialize the reader with a file path.

Methods

__init__(path)	Initialize the reader with a file path.
read()	Read the VTK file and return a Mesh.

Attributes

path	Return the file path.

property path: Path

Return the file path.

戻り値:

The path to the VTK file.

戻り値の型:

Path

read() → _PolyDataMesh

Read the VTK file and return a Mesh.

The full file content is stored so that vtk.js can parse it at render time. Point coordinates are extracted on the Python side for bounding-sphere and camera-framing calculations.

戻り値:

A mesh backed by the VTK file content.

戻り値の型:

Mesh

例外:

ValueError -- If the file format is invalid or unsupported.
