c++ - Methods belonging to multiple classes -

-

i making small project extension of larger body of work. part of larger project there class contains number of methods. use of these methods methods in new class feel there must better way duplicating code different class name! there way make method belong multiple classes (i should mention of c++)! cheers, jack

there speaking 2 possibilities:

  • inheritance: if new class (b) , class you're interested in (a) represent is a relationship.

  • composition: add class you're interested in (a) field in new class (b). can use methods.

if class has more methods need, violates single responsibility principle, , should split it. if b have methods same name a, consider introducing interface methods common both classes (in general this+composition seems better solution inheritance).

python - Django-easy-pdf: xhtml2pdf reporting reportlab 2.2+ is required, but 3.0 installed -

i'm trying give django-easy-pdf go, i'm having problems installing dependencies. i importerror: no module named xhtml2pdf.default when running django. to attempt fixing, did pip install xhtml2pdf , yields could not find downloads satisfy requirement pypdf (from xhtml2pdf) . so let's pip install --allow-unverified pypdf pypdf around that. completed without issues. when repeating pip install xhtml2pdf , software gets installed without issue. however, when launching django 1.6, get: importerror: reportlab version 2.1+ needed! . i have reportlab 2.2 or higher installed though, since pip freeze lists 3.0. it looks hardcoded in few files ( util.py , __init__.py ): if not (reportlab.version[0] == "2" , reportlab.version[2] >= "1"): raise importerror("reportlab version 2.1+ needed!") if not reportlab22: raise importerror, "reportlab toolkit version 2.2 or higher needed" how can fixed (except remove these c...

collision detection - C++ library for mesh to mesh intersection: what is available? -

-
i need calculate volume intersection , penetration depth between 3d triangular meshes (e.g. in .obj format), quite new computational geometry. in previous post ( mesh mesh intersections ) , google search, found few c++ libraries might appropriate job: cgal pqp libigl swift though, not sure 1 appropriate beginner. suggestion? libigl of version 1.1 has robust mesh boolean operations in igl/boolean/mesh_boolean.h . uses either implementation using cgal's exact arithmetic kernel or wrapper of cork (another option you). for now, libigl contains patched version of cork in libigl/external/cork , improves robustness. while implementing libigl's boolean ops, found cork faster not produce correct result (specifically, fails resolve intersections). libigl, using cgal backend, robust , still fast compared converting mesh cgal's nef_polyhedron , conducting csg operations , converting mesh. final conversion possible if result manifold. instead, libigl use...
