Overview

Create a 3D image based off of an STL file and user defined spacing. Additional, options exist for rotating the mesh, adding a 3MF file to create a "color-intensity" on the surface of the image, and flipping the image and mesh along the vertical axial plane.

The script produces 2 files: 1) Metaimage file for the image, 2) STL file just incase any rotations/flips were added (makes this file even if nothing was changed from the original STL file).

Notes:

• The spacing must be integeres, even if floats are input they will be converted.
• Adding a 3MF file will greatly increase the computation time depending on mesh size ~ 30 minutes for 1 million points.

Features

Converts STL file to a 3D image.

Options:

• Add 3MF file to transfer mesh color to surface insensity on the image.
• Allows mesh rotation before image creation.
• Flip image/mesh before output along the vertical axis in the axial plane.

Installation

Using pip:

pip install STLtoMask

Examples

Basic

from STLtoMask.converter import stl_to_mask

input_path = r'/path/to/STL_file'
output_path = r/path/to/export/data'
spacing = [1, 1, 1]

stl_to_mask(input_path, output_path, spacing)

Advanced

from STLtoMask.converter import stl_to_mask

input_path = r'/path/to/STL_file'
output_path = r/path/to/export/data'
spacing = [1, 1, 1]

threemf_path = r'Z:\Morfeus\Derek\2023-06-21_OCCR.3mf'
rotation = {'zxy': [10, 5, 20]}

stl_to_mask(input_path, output_path, spacing, three_mf_path, rotation, flip=True)
