Auto Redraw

自动重绘

You have probably noticed that a great way to test the movements of your IK chain, especially in combination with the Dynamics function of Soft IK, is to press the Play button (or hotkey: F8).

你可能已经注意到，一个很好的方法来测试你的 IK 链的运动，特别是结合动力学功能的软 IK，是按下播放按钮(或热键: F8)。

However, since the IK chain works with soft constraints, the animation reacts to a number of different factors. This means that the animation might not be finished at the last frame. The joints might still come to rest slowly. To display those changes without playing back the entire animation, you can use the Auto Redraw command. Once enabled, it will constantly update the calculations, displaying the reactions of your IK chain immediately.

然而，由于 IK 链是在软约束下工作的，所以动画会对许多不同的因素做出反应。这意味着动画可能不会在最后一帧结束。关节可能还是会慢慢地休息。要在不回放整个动画的情况下显示这些更改，可以使用“自动重绘”命令。一旦启用，它将不断更新计算，立即显示 IK 链的反应。

When choosing this command, the dialog will enable you to set the redraw step in milliseconds. If you have activated the Auto Redraw you will find the dialog already below the Object Manager. Normally, the animation will be played back in real-time; for PAL systems, that means 25 frames per second, for NTSC it is 30. Each frame will therefore be displayed for 1/25 or 1/30 of a second before it is updated again.

当选择此命令时，该对话框将允许您以毫秒为单位设置重绘步骤。如果你已经激活了自动重绘，你会发现对象管理器下面的对话框。通常情况下，动画会被实时播放; 对于 PAL 系统，这意味着25帧率/秒，对于 NTSC 来说是30秒。因此，每一帧将显示1/25或1/30秒，然后再次更新。

The default value of 50 milliseconds (20 frames per second) is quite enough to make the movements smooth. Note that each redraw costs processing power. Higher redraw times will cost more processor time. 50 milliseconds is a good average value. Very complex scenes may, however, require faster redraw times.

默认的50毫秒(20毫秒帧率)足以让移动变得平稳。请注意，每次重绘成本处理能力。更高的重绘时间将消耗更多的处理器时间。50毫秒是个很好的平均值。然而，非常复杂的场景可能需要更快的重画时间。
