In Vuo, the documents that you work with are called compositions. Start a new composition by going to .
The rounded rectangles in the composition window are called nodes. The area that you place nodes on is called the canvas.
For this example, you won’t need all of these nodes, just Fire on Display Refresh and Render Image to Window. So you can click on each of the rest of the nodes and hit ⌫ (Delete).
As you may have guessed from their titles, each node has a job or responsibility. The two nodes on the canvas will each perform a task that contributes to the animated pattern that you’re creating. The Render Image to Window node will be in charge of displaying the pattern in a window. The Fire on Display Refresh node will be in charge of the timing of the animation.
An animation is a series of images displayed in rapid succession. The fastest rate at which your computer monitor can display a series of images is called the display refresh rate. On many monitors, the display refresh rate is 60 times per second.
