Usage

Basic I/O

import polyxios as px

# Read any supported format
mesh = px.read("brain.vtk")

# Inspect
print(mesh.vertices.shape)      # (n_verts, 3)
print(len(mesh.element_types))  # number of elements

# Write to a different format
px.write(mesh, "brain.ply")
px.write(mesh, "brain.vtp")

Format-specific options

px.write(mesh, "brain.vtk", binary=True)
px.write(mesh, "brain.ply", binary=True, endian="little")

Every codec’s own options are listed on its page under Supported formats.

Where to go next

• Supported formats - the twenty-five supported formats, one page each

• Lazy loading - reading files larger than RAM

• Transforms - filtering, cleaning and merging meshes

• Command line interface (pxios) - the pxios command line

• Plugin system - teaching polyxios a new format
