    geometry3d

    A Python library for geometric objects in 3 dimentions

    Implemented classes of 3d objects: * Vector * Point * Line * Plane * LineSegment Yet incompletely implemented classes: * Triangle * Disk (closed circle) * Union (a collection of 3d objects) Each object has methods for finding its sizes, containing box or containing sphere. It finds intersection and distance or closest to another object part of itself. It also can tell if it contains the other object or is it contained by that. Where appropriate, it's easy to check orthogonality and parallelism. Vectors are sub-typed from numpy ndarray class. Extensive unit tests are included. Test coverage exceeds 95%. See documentation of the library internals in section Files ( https://sourceforge.net/projects/geometry3d/files/ ).

    Deepend

    Deallocate groups of objects in a single call

    Deepend is a storage pool with subpool capabilities for Ada 2022, Ada 2012, Ada 2005, and Ada 95. Memory allocations can be associated with subpools and subpools can be deallocated as a whole which provides a safer alternative than managing deletions of individual objects. It also is likely to be more deterministic and efficient than garbage collection.
