我有一个java程序，通过JAXB输出一个X3D文件。这是当前的输出。

我的问题是你可以看到插值占20个点，但是当它运行时它只运行了一半，然后快速回到开头。我不明白为什么它会在第10个间隔停止。我知道我错过了什么，但是什么？
顺便说一句，我是新人，所以你看到我能解决的任何问题，请继续告诉我。提前致谢。
答案 0 :(得分：0)
fraction_changed 输出0到1之间的值.IndsetInterpolator的键具有从0到20开始的整数值。这意味着只有第一个（0）和第二个（ 1）每当TimeSensor开始/结束时，值都将处于活动状态。基本上你的变换将被翻译5次到（0,0,0）和5次翻译成（10,0,0）。
要实现您想要的功能，您必须将键数组更改为： 关键[0 0.05 0.10 0.15 .... 0.95 1]
或将 person-time.time 路由到person-position.set_fraction。这将通过所有键值一次。
它应该以这种方式工作。
