关于立方体和 tikz 图片的一些问题

Question

我有三个立方体，我用 tikz 图片来画它们。现在，

1. 我怎样才能使这个图形的颜色更加突出？
2. 我使用‎\begin{tikzpicture}[t][tdplot_main_coords]‎‎它来绘制图像，结果是可以接受的，但是文件有错误。改用`\begin{tikzpicture}[tdplot_main_coords]‎‎'，错误得到纠正，但是图像显示更改为不正确。我该如何处理这个问题？

我的代码是：

Answer 1

我不确定你期望这个t选项能做什么，但要改变图形的视图，玩弄数字

\tdplotsetmaincoords{80}{125}

至于颜色，这些是在\draw命令中指定的，例如fill=blue!5。语法<color>!N意味着颜色与白色混合（我认为），N指定颜色的百分比，其余为白色。因此，blue!5您得到 5% 蓝色，95% 白色。

我不知道您所说的突出具体是什么意思，但您可以例如增加蓝色、黄色和红色的百分比。例如：

\documentclass[reqno]{amsart}
\usepackage{tikz}
\usepackage{tikz-3dplot}
\begin{document}
\tdplotsetmaincoords{80}{155} %perspective angles

\begin{figure}
\centering
\begin{tikzpicture}[tdplot_main_coords]

 \coordinate (o) at (0,0,0);

\draw[fill=blue!25] (0,0,2) -- (0,2,2) -- (2,2,2) -- (2,0,2) -- cycle;
\draw[fill=blue!25] (2,0,0) -- (2,0,2) -- (2,2,2) -- (2,2,0) -- cycle;
\draw[fill=blue!25] (0,2,2) -- (0,2,0) -- (2,2,0) -- (2,2,2) -- cycle;
\node (A) at (0.68,0.68,1) {\Huge H};
\draw[very thick, ->, dotted] (2,1,1) -- node[midway,above]{$\dfrac{dN}{dt}$}(3.6,1,1);

\draw[fill=yellow!25] (4,2,2) -- (4,2,0) -- (6,2,0) -- (6,2,2) -- cycle;
\draw[fill=yellow!25] (6,0,0) -- (6,0,2) -- (6,2,2) -- (6,2,0) -- cycle;
\draw[fill=yellow!25] (6,0,2) -- (4,0,2) -- (4,2,2) -- (6,2,2) -- cycle;
\draw[very thick, ->, dotted] (6,1,1) -- node[midway,above]{$\dfrac{dR}{dt}$}(7.6,1,1);
\node (A) at (4.68,0.68,1) {\Huge N};

\draw[fill=red!25] (8,2,2) -- (8,2,0) -- (10,2,0) -- (10,2,2) -- cycle;
\draw[fill=red!25] (10,0,0) -- (10,0,2) -- (10,2,2) -- (10,2,0) -- cycle;
\draw[fill=red!25] (10,0,2) -- (8,0,2) -- (8,2,2) -- (10,2,2) -- cycle;
