How to typeset Triforce?

Question

What would be the best practice approach to typeset the Triforce symbol known from the Nintendo® Zelda™ series?

Answer 1

Here is a nice shaded TikZ version which you can draw in variable sizes.

You have to call the \triforce macro with one parameter, which is the width of the Triforce, e.g. \triforce{10cm}.

\documentclass{article}

\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}

\usepackage[svgnames]{xcolor}

\usepackage{tikz}
\usetikzlibrary{shadings, calc}

\colorlet{triforcefilloutercolor}{Gold!50!Yellow}
\colorlet{triforcefillinnercolor}{white!80!triforcefilloutercolor}
\colorlet{triforceoutlineinnercolor}{white}
\colorlet{triforceoutlineoutercolor}{Goldenrod}

\tikzset{%
    triforcefillshade/.style={%
        inner color=triforcefillinnercolor,%
        outer color=triforcefilloutercolor%
    },%
    triforceoutlineshade/.style={%
        inner color=triforceoutlineinnercolor,%
        outer color=triforceoutlineoutercolor%
    }%
}

\newcommand{\triforce}[1]{%
    \begin{tikzpicture}%
        \newdimen\triforcewidth%
        \newdimen\triforceheight%
        \triforcewidth=#1%
        \pgfmathparse{sqrt(3)}%
        \pgfmathsetlength{\triforceheight}{\pgfmathresult / 2 * \triforcewidth}%
        %
        \foreach \x / \y in {0 / 0, 0.5\triforcewidth / 0, 0.25\triforcewidth / 0.5\triforceheight}%
        {%
            \shade[triforcefillshade, xshift=\x, yshift=\y]%
                (0, 0)  -- +(.5\triforcewidth, 0) -- +(60:.5\triforcewidth) -- cycle;%
            \shade[triforceoutlineshade, xshift=\x, yshift=\y]%
                (0, 0)  -- +(.5\triforcewidth, 0) -- +(60:.5\triforcewidth) -- cycle%
                (30:.0175\triforcewidth) -- ($(60:.5\triforcewidth) + (-90:.0175\triforcewidth)$) -- ($(0.5\triforcewidth, 0) + (150:.0175\triforcewidth)$) -- cycle;%
        }%
    \end{tikzpicture}%
}

\begin{document}
\triforce{10cm}
\end{document}

Answer 2

A simple tikz solution:

\documentclass{article}
\usepackage{tikz}
\begin{document}
\tikz\fill[yellow]
  (0,0)  -- +(1,0) -- +(60:1) -- cycle
  (1,0)  -- +(1,0) -- +(60:1) -- cycle
  (60:1) -- +(1,0) -- +(60:1) -- cycle
;
\end{document}

Answer 3

With stacks. The top one is a simple stack of \TriangleUp symbols, whereas the bottom one uses a shrunken \stackinset upon the same, to achieve a border, as shown on the wiki reference.

\documentclass{article}
\usepackage{stackengine,xcolor,bbding,graphicx}
\def\LTri{\stackinset{c}{}{c}{-.2pt}{\scalebox{.85}
  {\textcolor{yellow!20}{\TriangleUp}}}
  {\textcolor{yellow}{\TriangleUp}}}
\begin{document}
\textcolor{yellow}{\stackon[0pt]{\TriangleUp\TriangleUp}{\TriangleUp}}

\stackon[0pt]{\LTri\LTri}{\LTri}
\end{document}

Answer 4

Compile with XeLaTex :

\documentclass{article}
\usepackage{pifont}
\usepackage{color}
\begin{document}
I can triforce !

\noindent
~~\ding{115}\\
\ding{115}~\ding{115}

Even in yellow:

\color{yellow}{
\noindent
~~\ding{115}\\
\ding{115}~\ding{115}
}
\end{document}

Answer 5

Just for fun, with pict2e:

\documentclass{standalone}
\usepackage{pict2e}
\begin{document}
\begin{picture}(2,1.732050808)
\newsavebox{\tripart}
\savebox{\tripart}{\moveto(0,0)\lineto(1,0)\lineto(0.5,0.866025404)\closepath\fillpath}
\put(0,0){\usebox{\tripart}}
\put(1,0){\usebox{\tripart}}
\put(0.5,0.866025404){\usebox{\tripart}}
\end{picture}
\end{document}

Answer 6

Only with amssymb

\documentclass[a4paper]{article}

\usepackage[english]{babel}
\usepackage[utf8]{inputenc}
\usepackage{amssymb}

\begin{document}
\Huge%
\hspace{-8pt}$\blacktriangle$\vspace{-15pt}\\
$\blacktriangle$\hspace{-4pt}$\blacktriangle$
\end{document}

Answer 7

Based on Heiko Oberdiek's answer, there is --- just for the fun --- an even simpler drawing with TiKz.

\documentclass{article}
\usepackage{tikz}
\begin{document}
\begin{tikzpicture}
\fill[yellow] (0,0)  -- +(2,0) -- +(60:2) -- cycle;
\fill[white]  (60:1) -- +(1,0)  -- (1,0) -- cycle;
\end{tikzpicture}
\end{document}

Below the drawing with [blue!05] instead of [white], just to mess with Steven B. Segletes's screen.

And to get a "triforce symbol logo of 1em height", as szantaii suggests :

\documentclass{article}
\usepackage{tikz}
\newcommand{\triforce}{\resizebox{1em}{!}{
\begin{tikzpicture}
\fill[black] (0,0)  -- +(2,0) -- +(60:2) -- cycle;
\fill[white]  (60:1) -- +(1,0)  -- (1,0) -- cycle;
\end{tikzpicture}
}}
\begin{document}
I'd like to introduce the \triforce{} symbol.
\end{document}
