uLib

uLib is the base toolkit library for the CMT (Cosmic Muon Tomography) project, developed at the University of Padova and INFN Sezione di Padova, Italy.

It provides:

• Core – object model, timers, configuration, UUID utilities.
• Math – linear algebra (Eigen3), structured grids, voxel images, ray-tracing, image filters.
• Python bindings – full pybind11 interface for scripting and analysis workflows.
• Optional CUDA acceleration for voxel filtering (transparent RAM ↔ VRAM management).

Quick Start

Users (pip / poetry)Developers (CMake)

# Activate your conda/micromamba environment first
micromamba activate mutom

poetry install            # CPU build
USE_CUDA=ON poetry install # GPU build

conan install . --output-folder=build --build=missing
cmake --preset conan-release
cmake --build build --target uLib_python -j$(nproc)

export PYTHONPATH="$(pwd)/build/src/Python:$(pwd)/src/Python"

Then in Python:

import uLib

# Core
timer = uLib.Core.Timer()
timer.Start()

# Math
grid = uLib.Math.StructuredGrid([10, 10, 10])
grid.SetSpacing([1.0, 1.0, 1.0])

img = uLib.Math.VoxImage([10, 10, 10])
img.SetValue(0, 3.14)
print(img.GetValue(0))
