## Parameters

### Object

Parameter ID: `GV_HAIR_PROXIMITY_INPUT_OBJECT`

This is the object whose guides should be checked for proximity. If this node is active, the corresponding Hair object can also be placed into the **Reference** field.

### Point

Parameter ID: `GV_HAIR_PROXIMITY_INPUT_POINT` · Range: [XYZ ]

Enter the point data for the user-defined point in space to which the proximity of the nearest point on the hair or guide should be ascertained.

### Index

Parameter ID: `GV_HAIR_PROXIMITY_POINT_INT` · Range: [-2147483648..2147483647]

The index number of the nearest guide or hair point are output here. Each guide or hair point has a unique index number that can be entered into the **Index** port of a given Node.

### Guide

Parameter ID: `GV_HAIR_PROXIMITY_POINT_GUIDE` · Range: [-2147483648..2147483647]

The number of the guide nearest the user-defined point is located here. See [this](https://help.maxon.net/c4d/en-us/Content/html/GVHAIR_POINT.html.md) for more information about the numbering of guides.

### Segment

Parameter ID: `GV_HAIR_PROXIMITY_POINT_SEGMENT` · Range: [-2147483648..2147483647]

This port outputs the segment number of the segment nearest the nearest guide.

### Position

Parameter ID: `GV_HAIR_PROXIMITY_POINT_VEC` · Range: [XYZ ]

The next position on the guide or hair is output in vector form here.

### Segment Delta

Parameter ID: `GV_HAIR_PROXIMITY_POINT_T` · Range: [-∞..+∞]

This port outputs a corresponding position on the nearest guide segment as a value between 0 (segment begin) and **1** (segment end).
