Description

This extension gives defined behavior to fragment depth values which end up outside the conventional [0, 1] range. It can be used to ensure portability in edge cases of features like depthBias. The particular behavior is chosen to match OpenGL to aid porting or emulation.

• Extending PhysicalDeviceFeatures2, DeviceCreateInfo:

  • PhysicalDeviceDepthClampZeroOneFeaturesEXT

New Enum Constants

• EXT_DEPTH_CLAMP_ZERO_ONE_EXTENSION_NAME

• EXT_DEPTH_CLAMP_ZERO_ONE_SPEC_VERSION

• Extending StructureType:

VkPhysicalDeviceDepthClampZeroOneFeaturesEXT - Structure describing feature to control zero to one depth clamping

Members

This structure describes the following feature:

Description

If the PhysicalDeviceDepthClampZeroOneFeaturesEXT structure is included in the pNext chain of the PhysicalDeviceFeatures2 structure passed to getPhysicalDeviceFeatures2, it is filled in to indicate whether each corresponding feature is supported. PhysicalDeviceDepthClampZeroOneFeaturesEXT can also be used in the pNext chain of DeviceCreateInfo to selectively enable these features.

Fields

• depthClampZeroOne :: Bool

  depthClampZeroOne indicates that the implementation supports clamping the depth to a range of 0 to 1.
