Quick Start

Convert VTK to USD

from monai_physio import ConvertVTKToUSD

converter = ConvertVTKToUSD.from_files(
    data_basename="Heart",
    vtk_files=["heart_phase_00.vtk", "heart_phase_01.vtk"],
    time_codes=[0.0, 1.0],
)
stage = converter.convert("animated_heart.usd")

Create Anatomical Scene

from monai_physio import process_usd_anatomy

stage = process_usd_anatomy.create_anatomical_stage()
process_usd_anatomy.add_heart_model(stage, "heart.vtk")
process_usd_anatomy.add_lungs_model(stage, "lungs.vtk")
stage.Save()
