Class MTLRasterizationRateLayerDescriptor

  • All Implemented Interfaces:
    NSCopying, NSObject
    public class MTLRasterizationRateLayerDescriptor
extends NSObject
implements NSCopying
    [@interface] MTLRasterizationRateLayerDescriptor Describes the minimum rasterization rate screen space using two piecewise linear functions. The two piecewise linear function (PLF) describe the desired rasterization quality on the horizontal and vertical axis separately. Each quality sample in the PLF is stored in an array as single precision floating point value between 0 (lowest quality) and 1 (highest quality). The first sample in the array describes the quality at the top (vertical) or left (horizontal) edge of screen space. The last sample in the array describes the quality at the bottom (vertical) or right (horizontal) edge of screen space. All other samples are spaced equidistant in screen space. MTLRasterizationRateLayerDescriptor instances will be stored inside a MTLRasterizationRateMapDescriptor which in turn is compiled by MTLDevice into a MTLRasterizationRateMap. Because MTLDevice may not support the requested granularity, the provided samples may be rounded up (towards higher quality) during compilation. API-Since: 13.0
