Class

MDLNoiseTexture

A generator of texel data that creates a field of random noise.

Declaration

@interface MDLNoiseTexture : MDLTexture

Overview

Like other procedural MDLTexture subclasses, the MDLNoiseTexture class generates texel data only when that data is first referenced, and then caches it for future use.
