Description

It can be detrimental to performance for applications to have to define fake vertex attribute locations and buffer bindings for vertex shaders that may reference attribute locations for which there is no vertex data.

This extension allows applications to not have to specify fake vertex attribute locations, and if the vertex shader reads those attributes it will read (0,0,0,0) or (0,0,0,1).

VkPhysicalDeviceVertexAttributeRobustnessFeaturesEXT - Structure describing whether the vertex attribute robustness feature is supported by an implementation

Members

This structure describes the following feature:

Description

If the PhysicalDeviceVertexAttributeRobustnessFeaturesEXT 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. PhysicalDeviceVertexAttributeRobustnessFeaturesEXT can also be used in the pNext chain of DeviceCreateInfo to selectively enable these features.
