# GLKEffectPropertyTransform

Coordinate transform information for use in GLKit rendering effects.

```
class GLKEffectPropertyTransform
```

## Overview

The [`GLKEffectPropertyTransform`](/documentation/GLKit/GLKEffectPropertyTransform) class defines properties that provide the coordinate transformations to be performed when rendering the effect.

## Topics

### Configuring Modelview Properties
