# Projection Mapping

Projection mapping in LightAct usually follows these steps:

1. [**Projection study**](/projection-mapping/projection-study.md): this is the process where you analyse how many and what kind of projectors you will need and where you will place them. This process usually happens before you actually have projectors connected to the servers.
2. **Projection mapping**: this is the process of making sure the output of the projectors falls where it should and that the final look is as close to the intended one as possible. There are 2 kinds of Projection mapping:
   1. [*2D projection Mapping*](/projection-mapping/2d-projection-mapping-workflow.md): 2D projection mapping refers to projecting content on flat or curved surfaces such as screens and walls.
   2. [*3D Projection Mapping*](/projection-mapping/3d-projection-mapping-workflow.md): 3D projection mapping refers to projection on more complex 3D objects. This process requires an accurate 3D model of the projection object(s). This process may include using [Iris computer vision](https://lightact.com/iris/). In this workflow the content is usually rendered onto a 3D model of the projection object.

# Agent Instructions: 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:

```
GET https://docs.lightact.com/projection-mapping/projection-mapping.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
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.
