pyvista_wasm.OBJReader

class pyvista_wasm.OBJReader(path: str | Path)

Bases: object

Reader for Wavefront OBJ files (.obj).

Reads an OBJ ASCII file and produces a Mesh that delegates parsing to VTK.wasm’s vtkOBJReader at render time. Python extracts only the vertex coordinates so that camera framing and bounding-sphere queries work before rendering.

Parameters:

path (str or Path) – Path to the .obj file.

Examples

Try it with JupyterLite!

>>> import pyvista_wasm as pv
>>> reader = pv.OBJReader("model.obj")
>>> mesh = reader.read()

Go BackOpen In Tab

__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 OBJ file and return a Mesh.

Attributes

path	Return the file path.

property path: Path

Return the file path.

Returns:

The path to the OBJ file.

Return type:

Path

read() → _OBJMesh

Read the OBJ file and return a Mesh.

The full file content is base64-encoded and stored so that VTK.wasm can parse it at render time. Vertex coordinates are extracted on the Python side for bounding-sphere and camera-framing calculations.

Returns:

A mesh backed by the OBJ file content.

Return type:

Mesh

Raises:

ValueError – If the file contains no vertex data.
