Class EXTSamplerFilterMinmax

java.lang.Object

org.lwjgl.vulkan.EXTSamplerFilterMinmax

public final class EXTSamplerFilterMinmax
extends java.lang.Object

In unextended Vulkan, minification and magnification filters such as LINEAR allow sampled image lookups to return a filtered texel value produced by computing a weighted average of a collection of texels in the neighborhood of the texture coordinate provided.

This extension provides a new sampler parameter which allows applications to produce a filtered texel value by computing a component-wise minimum (MIN) or maximum (MAX) of the texels that would normally be averaged. The reduction mode is orthogonal to the minification and magnification filter parameters. The filter parameters are used to identify the set of texels used to produce a final filtered value; the reduction mode identifies how these texels are combined.

Promotion to Vulkan 1.2

All functionality in this extension is included in core Vulkan 1.2, with the EXT suffix omitted. The original type, enum and command names are still available as aliases of the core functionality.
