poc: Python OCE Composer
poc is a tool in the vein of OpenSCAD for creating 3D models in a high level language with a minimum of boilerplate.
poc programs are Python2 programs, executed in an environment that provides convenient shorthand for performing geometric operations.
Python2 is used instead of Python3 because a python3 compatible version of
vtk is not availble in debian stretch. However, the python3-like features of
print_function and division are automatically enabled.
poc uses OpenCASCADE (via pythonocc-core) to implement its geometric
operations. This means it has different strengths and weaknesses compared to
OpenSCAD, which uses CGAL. For instance, OpenCASCADE has fillet as a
first-class operation, while it lacks minkowski and hull which are quite
frequently used in OpenSCAD.
Setup
- Install dependencies
- Run setup, e.g.,
sudo python setup.py install - Invoke
pocview somefile.pocto lanuch a viewer. It autoupdates if you modify the input file. - Invoke
poc somefile.pocto createsomefile.stl - or use
#!/usr/bin/env pocso that./somefile.pocis executable
Dependencies
- OpenCASCADE Community Edition (OCE)
- pythonocc-core
- python-vtk6
Stability
The the design of the poc standard library is very much in flux, and there are likely to be compatibility-breaking changes as it develops.
