plyio¶
PLY file format.
This module implements support for reading and writing of PLY files.
- class plyio.PlyHeaderElement(name: str, count: int, properties: List[PlyHeaderProperty])¶
Header information about one element.
- count: int¶
Number of items
- element_size() int | None ¶
The total size of all properties of one element.
- name: str¶
Name of the element
- properties: List[PlyHeaderProperty]¶
List of properties
- to_header_line() str ¶
Format a property element line.
- class plyio.PlyHeaderProperty(name: str, kind: str, size: int | None)¶
Header information about one property.
- kind: str¶
Type (char, uchar, short, int, float, list int int, …)
- name: str¶
Name of the property
- size: int | None¶
Size of one item in bytes
- to_header_line() str ¶
Format a property header line.
- class plyio.PlyMesh(vertices: ndarray, indices: ndarray, normals: ndarray | None, header_elements: List[PlyHeaderElement])¶
All mesh data of a PLY file.
- property attributes: ndarray¶
Get auxiliary vertex attributes.
- has_attributes() bool ¶
Are auxiliary vertex attributes available?
- header_elements: List[PlyHeaderElement]¶
