我有一些图形，我相信它们足以展示我的需要，但我想更进一步，我想知道在 \shade[] 命令中可以使用什么样的设置来创建 3D 效果。
MWE 是红灯的绘图，我希望它看起来像这个 png 图形

这是我在 20 + 10 分钟内能够完成的事情...剩下的微调将花费更长的时间。编辑：添加了阴影。

请注意，我生活在不同的时区，因此太阳的位置与图片中的位置略有不同。如果您对此不满意，请查看这个帖子其中解释了如何自定义角度。

答案2
钛钾Z 不擅长 3D。特别是，它不支持照明 - 没有光源、阴影等概念。伪造总是可能的 - 如果你愿意，可以逐个像素地绘画 - 但这是毫无意义的浪费时间。
如果您确实需要自己绘制，请使用专为 3D 设计且能够处理光源的工具。有人提到过 Asymptote，但可能还有更好的选择。如果您将其创建为 2D 图像，Asymptote 很好，但如果您切换到 3D，它会坚持使用光栅输出。
然而，对于这幅图像来说，这种努力实际上是毫无意义的，因为高分辨率的光栅和矢量图已经可以从https://openclipart.org/detail/118837/traffic-light-dan-gerhar-01。下载 PDF 并使用\includegraphics是获得卓越品质的轻松途径。或者，您可以尝试下载 SVG 并进行转换。我最初使用 Inkscape 的尝试并不是很成功，但通过微调可能会做得更好。
作为参考，这是我使用 Inkscape 尝试的结果。我猜想这其中肯定有窍门，但这些留给读者练习。也就是说，我不知道它们是什么——我的转换非常不稳定，不幸的是，失败的次数多于成功的次数。（驴子工作正常；驴子和交通灯则不太好。）

答案3
我建议你应该针对每个目标使用合适的工具，例如蒂克兹专注于节点、文本、箭头、框等，而不是创建2D 图纸，虽然只要有技巧和必要的时间就可以完成，但这就像是徒手完成一样因此，您应该选择具有与免费软件相同基本特征的合适工具。因此，我建议使用 Inkscape，您可以在所见即所得的环境中绘图，如您所见，它可以安静地处理在 Tikz 和 Latex 中处理的 pdf 文件，可以获得更好的结果而不会影响质量，但可能会牺牲文件大小。（我希望不会太大）
测试结果改进了在 tikz 中生成的图像，在 inkscape 中修饰，利用 pdf 格式的兼容性，通过导入空白文档添加方程式，该文档中包含在 latex 中制作的方程式（花费任意时间，直到对结果满意为止，就我的情况来说，需要 37 分钟）才能得到这个。
当然，所有这些图像都是矢量图，您可以随意缩放而不会损失质量。
成本仅仅是文件大小：
- Tikz_pdf_文件：tikz2-5D.pdf -->7Kb。
- Inkscape SVG 包含导入的 pdf 和已编辑的--> 343Kb。
- 导出的 pdf 文件：2-5D.pdf-->25Kb。（这真是太棒了。）
- Inkscape SVG 导入方程式 latex pdf 和一些附加版本--> 373Kb。
- 导出的 pdf 文件：2-5Dred.pdf-->59Kb。（这个很不错）。
为了检查透明度，我使用了包\background，pdf 文件输出大小为：103Kb。
