petrify 0.3.0

Design Principles

• Novice focus. This library should make it as easy as possible to build and manipulate solids, shapes, and other geometry.

• Immutable operation. Immutable math is easier for novices to reason about. This library explicitly does not target strong real-time applications like games that demands mutability for performance.

• Pluggable engines. CSG is complicated. Different engines have different tradeoffs:

  • The pymesh engine is the default where the pymesh2 library is installed. It uses the IGL engine, which is mature and quite fast. However, building pymesh with IGL support can be difficult for novices and in certain environments (like Windows).

  • cython-csg is relatively fast, but still requires a cython build toolchain.

  • pycsg is a pure-python implementation. It is obviously quite slow, but works everywhere python does. For example, pure python environments like pyiodide can utilize this engine easily.
