volpy
A volume renderer for Python.
Volpy is a dual multi-process, multithread implementation of the ray casting method of volume rendering for Python supporting ambient and diffuse lighting. It supports visualizing scalar fields (Python functions) and scalar grids (NumPy arrays). Each of these may be assigned color also using Python functions or NumPy arrays.
Unit Tests
Unit tests are in the tests subdirectory. It is recommended you install volpy
in a virtual environment before testing:
virtualenv .
. bin/activate
pip install cython numpy
python3 setup.py install
./runtests.sh
Benchmarks
Benchmarking scripts are available in the benchmarks subfolder available as
executable Python scripts. They require PIL for image output.
Examples
import numpy as np
import volpy
center = np.array([0, 0, 2, 1])
def sphere(x):
norms = np.linalg.norm(x - center, axis=1)
return np.where(norms < 1, 1, 0)
scene = volpy.Scene(ambient=sphere, scatter=10)
image = scene.render((100, 100))
