Those topics deal with floating point and vector processing and are outside the scope of this article.

这些主题涉及的是浮点和向量处理，已经超出了本文的范围。

This routine is used to accomplish the same if one provides the interface handle which is generated by the IDL compiler, a type UUID and manager routine's entry point vector.

这个例程用于完成这个步骤，这需要提供IDL编译器生成的接口句柄、类型UUID和管理器例程的入口点向量。

And, that's the plane that contains the origin, the point, and the velocity vector.

并且这个平面包含了原点和动点，以及速度矢量。

youdao

it's clear that you want to add a vector that looks like that, because then you go from the start of this to the finish of that, you end up at the same point and you get this invisible 0 vector.

显然应该给它加上这样一个矢量,因为从这个矢量的起点指向那个矢量的终点,最终指向的是同一个点,你就得到这个不可见的零矢量
