## Node Properties

### Reference

Parameter ID: `GV_HAIR_INTERSECTION_OBJECT`

Place the Hair object that should be checked for intersection into this field.

### Mode

Parameter ID: `GV_HAIR_INTERSECTION_MODE`

Use this setting to define which guides or hairs should be checked for intersection:

- Guides: The **normal** guides, not those controlled by dynamics in their rest state.
- Dynamic Guides: The guides controlled by dynamics (internally, these are seen as copies of the guides in their rest state, which are affected by dynamics).
- Hairs: Each individual hair can be checked.

### Velocity Mode

Parameter ID: `GV_HAIR_INTERSECTION_VELOCITY_MODE`

Select between **Per Second** and **Per Frame**, depending on the velocity setting. Normally, **Per Second** will be selected automatically.
