I'm trying to create a "3D" schema of a grid where every "pixel" is colored with a random shade of blue (or whatever other color). As a tikz beginner, I'm already glad that I managed to tilt the grid, but so far I only managed to change the color for the whole grid. This is my MWE:
\documentclass{standalone}
\usepackage{tikz}
\usepackage{xcolor}
\begin{document}
\begin{tikzpicture}[every node/.style={minimum size=1cm}]
\begin{scope}[
every node/.append style={
yslant=0.5, xslant=-1}, yslant=0.5, xslant=-1
]
\fill[blue, fill opacity=.6] (0,0) rectangle (5.5, 5.5);
\draw[gray, very thick] (0,0) rectangle (5.5, 5.5);
\draw[step=5mm, gray] (0,0) grid (5.5, 5.5);
\end{scope}
\end{tikzpicture}
\end{document}
From what I saw in other posts, I fear I need to draw every pixel on its own?
\ComputeColor
to choose the desried random color. If that works for you, then this can be closed as a dupliacte of that question.
