如何在VMD上绘制多个pbc框？

Question

现在，我有：pbc box -color black -width 1 pbc set {4.541 4.541 6.463 69.5 69.5 90}

我该怎么做另一个？

Answer 1

pbc box_draw允许这样做。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]

如果您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
}
