Parse from generator. Raise StopIteration if the property could not be read.

Parse a PLY header from a readable file-like stream.

Parse a list of PLY element definitions.

Consume one element definition. The unconsumed input is returned along with a PlyElement instance.

Read the actual data from a PLY file.

Load a PLY element from a binary PLY file. The element may contain list properties.

Load a PLY element from an ASCII-format PLY file. The element may contain list properties.

Return generator over one item.

Write the data to a PLY file.

Save a PLY element to a binary PLY file. The element may contain list properties.

Save a PLY element to an ASCII-format PLY file. The element may contain list properties.
