# Inputs

You are here:

## Inputs

### Array Mode

Parameter ID: `ARRAYMODE`

The node can either query individual values, e.g., when the point positions of a geometry are passed to the *Sample Field* one after another within a loop to determine the field values for each of these points, or it can directly process an array of corresponding queries. Accordingly, the **Array Mode** then returns an array of measurement results, which you would have to unpack yourself.

### Field

Parameter ID: `FIELD`

This input can process a list of [Field objects](https://help.maxon.net/c4d/en-us/Content/html/58455.html.md). Such a list is provided, for example, directly by a MoGraph [Nodes Effector](https://help.maxon.net/c4d/en-us/Content/html/OENODES.html.md), or you can use this input directly as a user data input for a capsule to add an input element for *Field Lists* there. You’ll find an example of this [on this page](https://help.maxon.net/c4d/en-us/Content/html/NET_MAXON_NBO_NODE_SAMPLEFIELD.html.md).

### Global Matrix

Parameter ID: `MATRIX`

This should be the object's global matrix, which contains, for example, the local positions used for field evaluation.

### Location

Parameter ID: `LOCATION`

In **Array Mode**, this is the input for an array collection consisting of the three values: *position* (Vector64), *uvw* (Vector64), and *direction* (Vector64).

### Knot Position

Parameter ID: `VARIADIC_PROPS_POSITION` · Range: [0..100%]

This is the local position at which the assigned fields are to be evaluated. For example, this could be a point on a geometry.

### UVW

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

Use this section to specify the UVW values at the positions where the fields are to be evaluated. If you only want to determine the intensities of fields at point positions, you can ignore this information.

### Local Direction

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

If vectors are also being manipulated by the fields, you can specify the original direction at the local position to be evaluated here for each one. If you are only interested in evaluating field strengths, you can ignore this input.

### Index

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

### Count

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

These parameters are intended solely for internal processing and are not available to you as a user..
