Mesh Reducer

This project provides a Rust implementation for reading and reducing points from various 3D mesh file formats (STL, OBJ, PLY, and STEP) using a fast grid sampling method. The functionality is exposed to Python using PyO3.

Features

• Read STL, OBJ, PLY, and STEP files and extract points.
• Reduce the number of points using a fast grid sampling method.
• Python bindings for seamless integration with Python projects.

Supported Formats

• STL
• OBJ
• PLY
• STEP (initial implementation with future improvements expected)

Usage

Python

pip install mesh-reducer

Functions

load_mesh(file_path: Path, clusters: int) -> List[Tuple[float, float, float]]

Reduces the number of points in a mesh file using fast grid clustering.

Args:

• file_path (Path): Path to the mesh file.
• clusters (int): Number of clusters to reduce the points to.

Returns:

List[Tuple[float, float, float]]: A list of tuples containing the reduced points.

load_meshes(file_paths: List[Path], clusters: int) -> List[List[Tuple[float, float, float]]]

Reduces the number of points in multiple mesh files using fast grid clustering.

Args:

• file_paths (List[Path]): List of paths to the mesh files.
• clusters (int): Number of clusters to reduce the points to.

Returns:

List[List[Tuple[float, float, float]]]: A list of lists of tuples containing the reduced points for each file.
