# Fix Intersections

<div align="left"><figure><img src="/files/ZoHNVihJWShGl4fO26oI" alt=""><figcaption></figcaption></figure></div>

```
/**
 * Node that fixes mesh self-intersections and penetrations.
 * 
 * Pushes vertices outward to resolve collisions between mesh surfaces,
 * with optional smoothing to maintain surface quality.
 * 
 * Usage:
 * 1. Connect the mesh to fix and a collision target mesh
 * 2. Configure correction settings
 * 3. Click Apply to resolve intersections

| Parameter                                                 | Description                                                                                                                                                                        |
| --------------------------------------------------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| <p>MaxCorrectionIterations</p><p><code>integer</code></p> | Maximum number of iterations to resolve penetrations. Higher values ensure complete elimination but take longer.                                                                   |
| <p>CorrectionOffset</p><p><code>double</code></p>         | Minimum clearance to maintain from the target surface (in same units as mesh). Small positive value prevents numerical precision issues.                                           |
| <p>PostSmoothingIterations</p><p><code>integer</code></p> | Number of smoothing iterations to apply after pushing vertices to prevent sharp artifacts.                                                                                         |
| <p>PostSmoothingStrength</p><p><code>double</code></p>    | Smoothing Strength                                                                                                                                                                 |
| <p>DetailPreservation</p><p><code>double</code></p>       | <p>Weight factor for detail preservation. Higher values preserve more detail but may allow slight penetrations.<br>Range: 0.0 (no preservation) to 1.0 (maximum preservation).</p> |

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.meshmorpher.com/graph/geometry/fix-intersections.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
