Here you find nodes to modify the geometry.
Geometry Proximity

This node finds the closest position on the target for each point in the input geometry.
Inputs
| Entry | What it does |
|---|---|
| Geometry | The target object. |
| Group ID | Is evaluated on the face domain, and splits the input mesh into multiple parts, each with its own id. |
| Sample Position | The position where the computed location is stored. |
| Sample Group ID | Determines in which group the closest nearest surface is detected. |
Properties
Target Geometry

The element of the target geometry to calculate the distance from.
Outputs
| Entry | What it does |
|---|---|
| Position | Closest location on the surface of the target mesh, or the closest point in the target point cloud in Points mode. |
| Distance | Distance from the source position to the closest location in the target. |
| Is Valid | Wether the sampling was successful. It is false when the sampled group is empty. |
Index of Nearest

Retreive values from specific geometry elements.
| Entry | What it does |
|---|---|
| Inputs | Position: The position of the nearest element. · Group ID: The group ID of the nearest element. |
| Outputs | Index: The Index of the nearest element. · Has Neighbor: Has this element a neighbor. |
Raycast

This node sends a raycast and retreives data from the hit target.
Inputs
| Entry | What it does |
|---|---|
| Target Geometry | This is actually the source object that sends the ray. |
| Attribute | Attribute input. |
Interpolation

Mapping from the target geometry to hit points.
| Entry | What it does |
|---|---|
| Source Position | Source position input. |
| Ray Direction | A vector 3 for the ray direction. |
| Ray Length | The length of the ray. |
Properties
Data Type

What data to calculate on hit.
Output
| Entry | What it does |
|---|---|
| Is Hit | Has the raycast hit something? |
| Hit Position | The hit position if any. |
| Hit Normal | The normal of the hit point. |
| Hit Distance | The distance of the hit point. |
| Attribute | The attribute of the hit object. |
Sample Index

Retreive values from specific geometry elements.
Inputs
| Entry | What it does |
|---|---|
| Geometry | The source object to take the data from. |
| Value | The value to retreive. |
| Index | The index position of the value. |
Properties
Data Type

The type for the source and result data.
Domain

What kind of data to process.
Clamp
Clamp the indices to the size of the attribute domain.
Output
Value
The output value.
Sample Nearest

Retreives the element of a geometry closest to a position.
Inputs
| Entry | What it does |
|---|---|
| Geometry | The source object to take the data from. |
| Sample Position | The position of the source object. |
Properties

Domain
What data to process.
Output
Index
The index output.
