ios - Desaturate a live UIView layer (not a UIImageView) -

-

i'm wondering best way desaturate uiview—particularly, uisliderview custom appearance applied it. in ios 7, standard controls fade out tint colors when view appears on them (for example, share sheet or uialertview), since mine built uiimages, tint property doesn't apply it, , remain saturated. there good, easy way desaturate this, short of re-applying new uiappearance it? (if go route, able animate transition colored images greyscale ones?)

thanks in advance!

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...
