Description

This extension adds stricter requirements for how out of bounds reads from images are handled. Rather than returning undefined values, most out of bounds reads return R, G, and B values of zero and alpha values of either zero or one. Components not present in the image format may be set to zero or to values based on the format as described in Conversion to RGBA.

Issues

  1. How does this extension differ from VK_EXT_robustness2?

The guarantees provided by this extension are a subset of those provided by the robustImageAccess2 feature of VK_EXT_robustness2. Where this extension allows return values of (0, 0, 0, 0) or (0, 0, 0, 1), robustImageAccess2 requires that a particular value dependent on the image format be returned. This extension provides no guarantees about the values returned for an access to an invalid Lod.

Examples

None.

data PhysicalDeviceImageRobustnessFeaturesEXT Source #

VkPhysicalDeviceImageRobustnessFeaturesEXT - Structure describing the out-of-bounds behavior for an implementation

Members

The members of the PhysicalDeviceImageRobustnessFeaturesEXT structure describe the following features:

Description

If the PhysicalDeviceImageRobustnessFeaturesEXT structure is included in the pNext chain of PhysicalDeviceFeatures2, it is filled with values indicating whether the feature is supported.

Valid Usage (Implicit)

Constructors

PhysicalDeviceImageRobustnessFeaturesEXT 

Fields

  • robustImageAccess :: Bool

    robustImageAccess indicates whether image accesses are tightly bounds-checked against the dimensions of the image view. Invalid texels resulting from out of bounds image loads will be replaced as described in Texel Replacement, with either (0,0,1) or (0,0,0) values inserted for missing G, B, or A components based on the format.
