参数
•物体
Use this port to pass an object to be checked for overlapping, or drag an object into the Reference field.
使用此端口传递要检查是否重叠的对象，或者将对象拖动到 Reference 字段中。
•定位[ XYZ ]
Use this setting port to enter a position vector. This can be done more easily in the XPresso Editor by connecting the positions of corresponding objects or particles to the Position input port.
使用此设置端口输入位置向量。在 XPresso 编辑器中，通过将相应对象或粒子的位置连接到位置输入端口，可以更容易地实现这一点。
•速度[ XYZ ]
A velocity vector can be entered here, or simply connect the corresponding velocity vectors to the Velocity input port in the XPresso Editor.
可以在这里输入速度矢量，或者将相应的速度矢量连接到 XPresso 编辑器中的速度输入端口。
How can the velocity vectors of (normally) animated objects be ascertained?
如何确定(正常情况下)动画物体的速度矢量？
Drag the object into the XPresso Editor and subsequently activate the History Level setting with a value of at least 1. Finally, select Position Velocity as your output port.
将对象拖动到 XPresso 编辑器中，然后激活至少为1的历史记录级别设置。最后，选择位置速度作为输出端口。
•半径[-∞ . . + ∞]
This is the radius of the (virtual) spherical area of detection that is placed around a given position that should be checked for collision with guides or hairs. Enter a value greater than 0, otherwise no intersections will take place.
这是放置在给定位置周围的(虚拟)探测球面区域的半径，应该检查是否与导轨或毛发发生碰撞。输入一个大于0的值，否则不会发生交叉。
十字路口•
The result of this output port is a Boolean true or false, depending on whether or not intersections take place.
此输出端口的结果是布尔值 true 或 false，具体取决于是否发生交叉。
Guide[-2147483648..2147483647]•
指南[-2147483648. . 2147483647]•
This port outputs the guide number of the intersecting guide.
此端口输出交叉指南的指南号。
Segment[-2147483648..2147483647]•
部分[-2147483648. . 2147483647]•
This port outputs the segment number of the intersected segment.
此端口输出相交段的段号。
段 Delta [-∞ . . + ∞] ·
This port outputs the exact position at which a given segment was intersected. A value between 0 (segment start) to 1 (segment end) will result.
此端口输出给定段与其相交的精确位置。结果是0(段开始)到1(段结束)之间的值。
Ray Delta [-∞ . . + ∞]•
This port outputs the exact position at which a given velocity vector was intersected. A value between 0 to 1 will result.
这个端口输出给定速度矢量相交的精确位置。结果是0到1之间的值。
位置[ XYZ ]•
This port outputs the point of intersection on the guide containing the velocity vector as vector.
这个端口输出的交叉点上的指南包含的速度矢量作为矢量。
