关于创建 3D 精美盒子

Question

亲爱的社区成员们，

我想通过结合第一个框（有一个简单的矩形）和第二个框来绘制一个 3D 精美框。您有什么想法吗？

这些分别是第一个和第二个框的 Latex 代码。

第一个代码（在 \begin{document} 环境之外编写）：

\usepackage{tikz}
\usetikzlibrary{calc}
\xdefinecolor{mycolor}{HTML}{1475bb} % Neutral Blue
\colorlet{bancolor}{mycolor}

\def\bancolor{mycolor}
\newenvironment{mybox}[3][]{%
\begin{tikzpicture}[#1]%
    \def\myboxname{#3}%
    \node [draw, line width=0.5mm, inner sep=1.5ex,text width=#2]% good 
options: minimum height, minimum width  , fill={mycolor!30}
    (BOXCONTENT) \bgroup\rule{0pt}{3ex}\ignorespaces
}{%
\egroup;
\node [right,inner xsep=1em,fill=bancolor!50,outer sep=0pt,text 
height=2ex,text depth=.5ex, text =black, font=\bf] (BOXNAME) 
at ([shift={(-1em,0pt)}]BOXCONTENT.north west) {\myboxname};
\fill[bancolor] (BOXNAME.north east) -- +(-1em,1em) -- +(-1em,0) -- cycle;
\fill[bancolor] (BOXNAME.south west) -- +(1em,-1em) -- +(1em,0) -- cycle;
\end{tikzpicture}
}

我在 \begin{document} 环境中调用它，如下所示：

\begin{mybox}{\textwidth}{Title}
    \justifying
    Hello World!
\end{mybox}

第二段代码（在 \begin{document} 环境中编写）：

\smartdiagramset{
    uniform color list=gray!60!black for 2 items,
    back arrow disabled=true,
}
\smartdiagram[flow diagram:horizontal]{PGF}

问候。Widad

tcolorbox以下是使用和的实现TikZ。

\documentclass{article}

\usepackage{blindtext}

\usepackage[most]{tcolorbox}

\usetikzlibrary{calc}

\definecolor{bluebg}{rgb}{0.5,0.7,0.84}
\definecolor{trianglebg}{rgb}{0.09,0.41,0.69}


\makeatletter
\tcbset{%
  decorationwidth/.store in=\kv@decoration@width,
  decorationwidth=10pt,
  boxedtitlecolor/.colorlet=tcbcol@boxedtitle,
  decorationcolor/.colorlet =tcbcol@decorationcolor,
  decorationcolor=trianglebg,
  boxedtitlecolor=bluebg,
}
\newtcolorbox[auto counter]{myboxother}[2][]{%
  enhanced, sharp corners,
  drop shadow,
  attach boxed title to top left={xshift=-\kv@decoration@width,yshift=-\tcboxedtitleheight/2,yshifttext=-\tcboxedtitleheight/2},
  coltitle=black,
  boxed title style={toprule=0pt,bottomrule=0pt,leftrule=0pt,frame hidden,enhanced,colback=tcbcol@boxedtitle,sharp corners},
  underlay boxed title={ 
    \coordinate (refpointsouth) at ($(title.south west)+(0pt,0mm)$);
    \filldraw[line width=0pt,tcbcol@decorationcolor] 
    (refpointsouth)  -- ($(refpointsouth) + (\kv@decoration@width,0)$) -- +(0pt, -\kv@decoration@width) -- cycle;
    \coordinate (refpointnorth) at ($(title.north east)-(\kvtcb@[email protected],0pt)$);
    \filldraw[line width=0pt,tcbcol@decorationcolor]
    (refpointnorth)  -- ($(refpointnorth) + (-\kv@decoration@width,0pt)$) -- ($(refpointnorth) +(0pt, \kv@decoration@width)$) -- cycle;
    }
  ,
  title={#2},#1,  
}
\makeatother

\begin{document}

\begin{myboxother}[decorationwidth=15pt]{My title}
  Hello World

  \blindtext
\end{myboxother}


\begin{tcolorbox}[enhanced,interior style={top color=white,bottom color=white!60!black}, drop shadow]
  Hello World
  \blindtext
\end{tcolorbox}

or a small box

\tcbox[enhanced,interior style={top color=white,bottom color=white!60!black}, drop shadow south]{Hello World}

\end{document}
