pic2stl 10.0.12

img2stl is a Python package that converts an image to a 3D STL models.

pic2stl Image Converter

Overview

pic2stl is a Python package that converts images to 3D STL models. It reads an image, translates it into a 3D mesh, and exports the mesh in STL format. This package is ideal for creating 3D printable models from logos, silhouettes, and other high-contrast images.

Features

• Convert images to 3D STL meshes
• Set extrusion height for 3D models
• Optionally add a base plane for enhanced model adhesion
• Compatible with any mainstream image format

Installation

To use this package, ensure that you have the required dependencies installed:

pip install numpy Pillow numpy-stl scipy

Usage

Function

def image_to_stl(image_path, output_path, extrusion_height, add_base=False, base_thickness=0)

Parameters

• image_path: Path to the input image.
• output_path: Path to save the generated STL file.
• extrusion_height: Height of the 3D model extrusion.
• add_base (Optional, default False): Adds a base plane if set to True.
• base_thickness (Optional, default 1): Thickness of the base plane.

Example

# Convert an image to STL
image_to_stl('path/to/input_image.png', 'output.stl', extrusion_height=3, add_base=True, base_thickness=2)

How It Works

1. Load Image: The function reads the input image and converts it to grayscale if needed.
2. Binary Conversion: Pixels above a specific threshold are considered "on," and those below are "off."
3. Mesh Creation: A 3D mesh is generated based on the "on" pixels, extruding vertically.
4. Optional Base: Adds an optional base to the bottom of the model for stability.
5. Export to STL: The mesh is then exported to STL format.
