Flaga Nepalu ( Wikipedia , Numberphile ) wygląda zupełnie inaczej. Zawiera również szczegółowe instrukcje rysowania (zawarte w artykule w Wikipedii). Chcę, żebyście stworzyli program, który narysuje flagę Nepalu.

Użytkownik wprowadza żądaną wysokość flagi (od 100 do 10000 pikseli), a program wysyła flagę Nepalu. Możesz wybrać dowolny sposób narysowania flagi: wszystko, od grafiki ASCII po OpenGL.

To jest konkurs popularności, więc zwycięzca otrzyma najwyższą głosowaną odpowiedź 1 lutego, więc nie martw się o długość kodu, ale pamiętaj, że krótszy kod może uzyskać więcej głosów.

Jest tylko jeden wymóg: nie wolno korzystać z zasobów sieciowych.

Baw się dobrze :)

Matematyka

Tymczasowa konstytucja Nepalu - Załącznik 1 (w odniesieniu do art. 6), s. 260 i 262, zawiera 25 szczegółowych instrukcji na temat budowy flagi. (patrz http://www.ccd.org.np/resources/interim.pdf ). Liczby w komentarzach odnoszą się do odpowiednich instrukcji w konstytucji.

Będziemy potrzebować funkcji, aby narysować równoboczne trójkąty i określić odległość od punktu do linii:

ClearAll[triangle]
triangle[a_?NumericQ,b_?NumericQ,c_?NumericQ,labeled_:True]:=
Block[{x,y,pt,sqr},sqr=#.#&;
pt[a1_,b1_,c1_]:=Reduce[sqr[{x,y}]==b1^2&&sqr[{x,y}-{a1,0}]==c1^2&&y>0,{x,y}];
{(
(*Polygon[{{0,0},{a,0},{x,y}}]*)
Polygon[{{-a/2(*0*),0},{a/2,0},{x-a/2,y}}]),
If[labeled,
{Text[Style[Framed[a,Background->LightYellow],11],{a/2,0}],
Text[Style[Framed[b,Background->LightYellow],11],{x/2,y/2}],
Text[Style[Framed[c,Background->LightYellow],11],{(a+x)/2,y/2}]},{}]}/.ToRules[pt[a,b,c]]]

dist[line_,{x0_,y0_}]:=(Abs[a x0+b y0+c]/.{x0-> m[[1]],y0-> m[[2]]})/Sqrt[a^2+b^2]; (* used below *)

Pozostały kod, z numerami odnoszącymi się do instrukcji. Zdecydowanie najtrudniejszą częścią jest wytwarzanie promieni dla księżyca i słońca. GeometricalTransformationprzydaje się do wykonywania tłumaczeń i rotacji.

Poniższa flaga, z powyższego kodu, jest wykonana zgodnie z instrukcjami zawartymi w konstytucji.

Kolory są modyfikowane, aby ułatwić przeglądanie linii konstrukcyjnych. Litery odnoszą się do punktów i linii w instrukcji.

Nawiasem mówiąc, flagi świata można wywoływać bezpośrednio w Mathematica. Na przykład:
