# MouseParams

Parameters describing mouse interaction in 3D space.

## Declaration

```swift
struct MouseParams
```

## Overview

Overview This structure captures both the position and direction of a mouse cursor projected into 3D coordinates, commonly used for ray casting or spatial interactions.
