Class KHRShaderFloatControls

java.lang.Object

org.lwjgl.vulkan.KHRShaderFloatControls

public final class KHRShaderFloatControls
extends java.lang.Object

Description

The VK_KHR_shader_float_controls extension enables efficient use of floating-point computations through the ability to query and override the implementation's default behavior for rounding modes, denormals, signed zero, and infinity.

VK_SHADER_FLOAT_CONTROLS_INDEPENDENCE_32_BIT_ONLY_KHR

public static final int VK_SHADER_FLOAT_CONTROLS_INDEPENDENCE_32_BIT_ONLY_KHR

VkShaderFloatControlsIndependenceKHR - Enum specifying whether, and how, shader float controls can be set separately

Description

• SHADER_FLOAT_CONTROLS_INDEPENDENCE_32_BIT_ONLY_KHR specifies that shader float controls for 32-bit floating point can be set independently; other bit widths must be set identically to each other.
• SHADER_FLOAT_CONTROLS_INDEPENDENCE_ALL_KHR specifies that shader float controls for all bit widths can be set independently.
• SHADER_FLOAT_CONTROLS_INDEPENDENCE_NONE_KHR specifies that shader float controls for all bit widths must be set identically.

Description

• SHADER_FLOAT_CONTROLS_INDEPENDENCE_32_BIT_ONLY_KHR specifies that shader float controls for 32-bit floating point can be set independently; other bit widths must be set identically to each other.
• SHADER_FLOAT_CONTROLS_INDEPENDENCE_ALL_KHR specifies that shader float controls for all bit widths can be set independently.
