Description

This extension allows an application to specify areas of the render target where the fragment shader may be invoked fewer times. These fragments are broadcasted out to multiple pixels to cover the render target.

The primary use of this extension is to reduce workloads in areas where lower quality may not be perceived such as the distorted edges of a lens or the periphery of a user’s gaze.

Synopsis

Documentation

data PhysicalDeviceFragmentDensityMapFeaturesEXT Source #

VkPhysicalDeviceFragmentDensityMapFeaturesEXT - Structure describing fragment density map features that can be supported by an implementation

Members

The members of the PhysicalDeviceFragmentDensityMapFeaturesEXT structure describe the following features:

Description

If the PhysicalDeviceFragmentDensityMapFeaturesEXT structure is included in the pNext chain of PhysicalDeviceFeatures2, it is filled with values indicating whether each feature is supported. PhysicalDeviceFragmentDensityMapFeaturesEXT can also be included in pNext chain of DeviceCreateInfo to enable the features.

data RenderPassFragmentDensityMapCreateInfoEXT Source #

VkRenderPassFragmentDensityMapCreateInfoEXT - Structure containing fragment density map attachment for render pass

Description

The fragment density map is read at an implementation-dependent time with the following constraints determined by the attachment’s image view flags:

The fragment density map may additionally be read by the device during PIPELINE_STAGE_FRAGMENT_DENSITY_PROCESS_BIT_EXT for any mode.

If this structure is not present, it is as if fragmentDensityMapAttachment was given as ATTACHMENT_UNUSED.
