c++ - Question about how to general a bezier curve by inputing several points -

-

i want generate bezier curve pass through several points input mouse.these points more four,can me , give me suggestions how implent it? more thanks. luck!

you have solve distance between points along curve first u & v.

generally, shortest arc lengths between points approx. best curve.

p0 , p3 endpoints; f , g 2 points along curve.

d1 distance between p0 , f; d2 between f , g; d3 between g , p3.

solving control points, p1 , p2:

let u=d1/(d1+d2+d3); v=(d1+d2)/(d1+d2+d3)

unit testing - How to mock PreferenceManager in Android? -

-
i've written class using context , third party library , sharedpreferences preferencemanager . it's possible mock context , third party library can mocked using mocking framework, preferencemanager ? i have 2 methods: public void savestring(thirdpartyobject obj) { sharedpreferences apppreferences = preferencemanager.getdefaultsharedpreferences(mcontext); sharedpreferences.editor editor = apppreferences.edit(); editor.putstring(mcontext.getstring( r.string.preferences_string_name), obj.getstring()); editor.commit(); } and corresponding, loads preferences. it doesn't want mock instance of preferencemanager (which used in preferencefragment or preferenceactivity ). you want either: a mock sharedpreferences , in case can mock context#getsharedpreferences (which called preferencemanager#getdefaultsharedpreferences anyhow). you'll have make mock sharedpreferences.editor if preferences edited, above. know how moc...
