新问题

是否有任何乳胶包可以绘制不同分子的球和棒模型（或用于不同目的但可用于绘制球和棒模型的包）。 球和棒模型如下： 在此处输入图片描述

我目前正在使用 avogadro -> 导出为 svg -> inkscape svg -> pdf+latex -> 插入文档。我更喜欢 tikz 包。

新问题

我发现 Avogadro 可以导出原子的坐标。我想知道如何制作连接圆柱体并在圆柱体上添加阴影。我还想改变视角，有没有比 tikz 3d 视图更自然的 3d 视图？这是我尝试绘制的分子的 TiKz 代码（不是上面的那个）

上面的代码没有将圆柱体作为键，而是仅通过函数将线作为键\draw。如何使圆柱体着色并更改 3D 视角？
