java - Using regular expressions to rename a string -

-

in java, want rename string ends ".mp4"

suppose have encoded link, looking follows:

string link = www.somehost.com/linkthatineed.mp4?e=13974etc...

so, how rename link string ends ".mp4"?

link = www.somehost.com/linkthatineed.mp4  <--- that's need final string be.

another way split string ".mp4" split char , add again :)

something :

string splitchar = ".mp4"; string link = "www.somehost.com/linkthatineed.mp4?e=13974etcrezkhjk" string finalstr = link.split(splitchar)[0] + splitchar;

easy ^^

ps: prefer pass regex ask more knowledge regex ^^

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...
