Package org.lwjgl.opengl

Class KHRShaderSubgroup

java.lang.Object

org.lwjgl.opengl.KHRShaderSubgroup

public final class KHRShaderSubgroup
extends Object

Native bindings to the KHR_shader_subgroup extension.

This extension enables support for the KHR_shader_subgroup shading language extension in OpenGL.

The extension adds API queries to be able to query

• the size of subgroups in this implementation (SUBGROUP_SIZE_KHR)
• which shader stages support subgroup operations (SUBGROUP_SUPPORTED_STAGES_KHR)
• which subgroup features are supported (SUBGROUP_SUPPORTED_FEATURES_KHR)
• whether quad subgroup operations are supported in all stages supporting subgroup operations (SUBGROUP_QUAD_ALL_STAGES_KHR)

In OpenGL implementations supporting SPIR-V, this extension enables the minimal subset of SPIR-V 1.3 which is required to support the subgroup features that are supported by the implementation.

Requires OpenGL 4.3.
