你第一次使用vvvv吧,还在琢磨怎么学,怎么用它做些有用好玩的事。抽点空,花20分钟就能过一遍基本教程,便可对vvvv有个基本了解。

预备,出发

当你运行vvvv时,它会自动运行一个示范程序。如果你已经熟悉它了,可以通过删除vvvv程序目录里的文件Args.txt来跳过它。可以使用windows的标准快捷键 ALT+F4来关闭vvvv。它会询问你是否需要保存一些文件,点击 Don't save and Close,不存直接关闭就好了。

再次运行vvvv,示范程序不再出现。你只能看到一个灰色窗口,一个我们称之为 Patch (程序片)的东西. 欢迎使用vvvv。

前言

vvvv不是用文本编程界面来写程序,取而代之的是用图形构件来编程。程序是写在 程序片?里的。独立的操作块或函数表示为盒子(称为结点 nodes?)。 结点之间用鼠标来勾勒或修改连线,从而建立起让数据从一个结点传往另一个结点的结构。

一个结点可能有三种基本操作中的一种:产生、处理和输出数据,也可以是这些的组合。每个结点都有一些输入输出,用结点顶部和底部的黑色的小方块来表示它们,这些叫做引脚 pins?

结点可以通过在它们的引脚之间建立连结来相互连接起来。
与文本编程相比,输入引脚可以代表函数的参数或自变量,而输出引脚表示函数的结果。

理论就到此为止,现在让我们怀一下旧,说Hello World!
