android - View.postDelayed why is it an instance method? -

-

in android platform, view object has instance method postdelayed, according documentation:

causes runnable added message queue, run after specified amount of time elapses. runnable run on user interface thread.

my questions:

  1. why method has instance method of view?
  2. would different if call postdelayed in 1 view instead of another?

thanks.

why method has instance method of view?

it references mattachinfo data member, in current implementation, , in turn data member's mhandler, handler postdelayed() work (if mattachinfo not null). welcome read of in the source code.

would different if call postdelayed in 1 view instead of another?

in theory, 2 view instances work separate handler instances. however, standpoint of documented behavior, there should no difference.

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...
