# GaussianSplatResource.ProjectionMode

Controls how 2D splat footprints are computed from 3D Gaussian primitives:

## Declaration

```swift
enum ProjectionMode
```

## Overview

Overview GaussianSplatResource.ProjectionMode.perspective — Projects splats using a standard perspective projection. GaussianSplatResource.ProjectionMode.tangential — Projects splats using a tangential approximation. May result in fewer artifacts.
