Tengo una imagen tikz que tiene elementos repetidos. Ahora mismo los estoy definiendo individualmente. Pero me gustaría tener un código que defina una plantilla-triángulo cuyas dimensiones controlo (como lo hago en mi ejemplo a través de p1,q1) y uso la rotación para controlar la orientación.
(Tenga en cuenta que este ejemplo tiene solo fines ilustrativos. Quiero crear patrones más complicados usando otras formas y me gustaría evitar el uso de más bibliotecas)
Mi código:
\documentclass[tikz]{standalone}
\usetikzlibrary{positioning,graphicx,calc}
\begin{document}
\begin{tikzpicture}
% Gridline
\coordinate (x1) at (-4,+0);
\coordinate (x2) at (+0,-4);
\coordinate (x3) at (+4,+0);
\coordinate (x4) at (+0,+4);
\coordinate (k) at (+0,+0);
\coordinate (p1) at (+4,+0); %Triangle variable
\coordinate (q1) at (+0,+4); %Triangle variable
%---------------------------------
\coordinate (G1) at ($(x1)+(x2)$);
\coordinate (G2) at ($(x3)+(x4)$);
\draw [step=0.5cm,draw=gray] (G1) grid (G2);
%\draw [fill=yellow,opacity=0.5] ($(x1)+(x4)$)--(G2)--($(x3)+(x2)$)--(G1);

\coordinate (b1) at (p1);

\coordinate (A1) at ($(B1)-(b1)$);

Quizás no sea el mejor tikzestilo para manejar esto, pero funciona incluso sin las bibliotecas que faltan en su ejemplo.
\documentclass[tikz]{standalone}
\newcommand{\tri}[1]{%
\draw[#1] (0,0) -- (4,0) -- (4,4) -- cycle;
}
\begin{document}
\begin{tikzpicture}
\tri{fill=black}
\tri{fill=red,rotate=90}
\tri{fill=green,rotate=180}
\tri{fill=blue,rotate=270}
\end{tikzpicture}
\end{document}

Quizás puedas considerar usar pics. Puedes usarlos para definir una figura tikz compleja y reutilizarla. Es posible definirlos con argumentos o incluso cambiar algunas propiedades cuando finalmente se dibujen.
El siguiente código muestra dos ejemplos con sus figuras. mytriangledefine un triángulo cuadrado con origen en un vértice con tres argumentos: color de relleno y longitud de dos lados. El segundo ejemplo define la imagen "compleja".
\documentclass[tikz, border=2mm]{standalone}
\usetikzlibrary{positioning}
\tikzset{
pics/mytriangle/.style n args={3}{
code={
\fill[#1] (0,0)--++(0,#2)--++(#3,0)--cycle;
}
},
myfigure/.pic={
\fill[black] (0,0) rectangle ++(-1,-1);
\fill[blue] (-1,0) rectangle ++(-3,-1);
\fill[green] (-4,0)-- ++(-1,0)--++(1,-1)--cycle;
\fill[blue] (0,-1) rectangle ++(-1,-3);
\fill[green] (0,-4)-- ++(-1,0)--++(1,-1)--cycle;
\fill[red] (-4,-1)-- ++(0,-3)--++(3,0)--cycle;
}
}
\begin{document}
\begin{tikzpicture}
\foreach \a/\c in {0/red,90/green,180/blue,270/black}
\pic[rotate=\a] at (0,0) {mytriangle={\c}{2}{2}};
\begin{scope}[xshift=4cm]
\foreach \a/\c in {0/red,90/green,180/blue,270/black}
\pic[rotate=\a] at (0,0) {mytriangle={\c}{1}{1.8}};
\end{scope}
\begin{scope}[xshift=8cm]
\foreach \a/\c in {0/red,90/green,180/blue,270/black}
\pic[rotate=\a] at (0,0) {mytriangle={\c}{1.5}{1}};
