如何在VMD上绘制多个pbc框？

Question

现在，我有： pbc盒-颜色黑色-宽度1 pbc集{4.541 4.541 6.463 69.5 69.5 90}

我该怎么做？

Answer 1

pbc box_draw允许这样做。示例：

# draw small box
pbc set {10 10 10}
set box0 [pbc box_draw -width 1 -color black]

# draw large box
pbc set {15 15 15}
set box1 [pbc box_draw -width 1 -color black]

如果以后需要删除一个框，可以这样做：

# delete all objects associated with the box
foreach i $box0 {
    graphics top delete $i
}
