# Shadow Plane

**Shadow Plane** is a performant way to get floor shadows in your browser WebGL scene. A projection of the geometry is done from above. The distance of the geometry from the top of the projection to the **Shadow Plane** is calculated. Then a texture is saved and applied to the **Shadow Plane** asset. Meshes closer to the **Shadow Plane** appear darker and meshes farther away appear a lighter grey, much like a depth map. Threekit then exposes features to adjust the look of the direction and direction of the projection. The **Shadow Plane** doesn’t export to AR and is a great option for adding more realism to your browser WebGL scene.

## 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://community.threekit.com/platform-documentation/catalog-2.0-docs/project-data/assets/nodes/lights/shadow-plane.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.
