QLab通过脚本校准投影映射面

QLab通过脚本校准投影映射面 此脚本来自QLab论坛 原贴是一位网友求助：

我正在制作一个节目，我使用许多视频面将行星视频投影到舞台上的各种泡沫球体（尺寸在 40～90 厘米之间）。我正在寻找一种简单的方法来在演出前校准所有表面以精确投影，因为球体的位置可能会有几厘米的变化。有没有比编辑每个表面更简单的方法，例如通过一个脚本来调整每个表面的原点参数，通过按键（向上、向下、向左）轻推它们？

作者micpool回复：主要的障碍是你不能得到当前的表面原点，因为没有脚本钩子，所以无法使用OSC查询来返回这个属性。但是，可以手动将表面ID和表面原点的当前设置输入到用于存储变量的虚拟文本提示中，如下所示：
原点X存储在翻译X中
翻译Y中的原点Y
文本中的表面ID
按比例微调量X
使用此方法，可以在每个表面使用4个脚本用于上下左右调整，也可以通过热键触发。

以下为脚本：

--nudge DOWN  Surface 1
set theStore to "S1" --q number of cue used to store current position of origin for this surface 
---------------------------------------
tell application id "com.figure53.QLab.4" to tell front workspace
	set the originX to (translation x of cue theStore)
	set theID to text of cue theStore
	set theNudge to scale x of cue theStore
	set the originY to (translation y of cue theStore) + theNudge
	set the translation y of cue theStore to the originY
	set theOSC to "/settings/video/surfaces/" & theID & "/0/origin {" & (originX as integer) & "," & (originY as integer) & "}"
	do shell script "echo " & quoted form of theOSC & " | nc -u -w 0 localhost 53535"
end tell

	set the originX to (translation x of cue theStore)
	set the originY to (translation y of cue theStore) - theNudge
	set the translation y of cue theStore to the originY
	set theOSC to "/settings/video/surfaces/" & theID & "/0/origin {" & (originX as integer) & "," & (originY as integer) & "}"
