C Specification
The VkPhysicalDeviceProvokingVertexFeaturesEXT
structure is defined
as:
// Provided by VK_EXT_provoking_vertex
typedef struct VkPhysicalDeviceProvokingVertexFeaturesEXT {
VkStructureType sType;
void* pNext;
VkBool32 provokingVertexLast;
VkBool32 transformFeedbackPreservesProvokingVertex;
} VkPhysicalDeviceProvokingVertexFeaturesEXT;
Description
-
sType
is the type of this structure. -
pNext
isNULL
or a pointer to a structure extending this structure. -
provokingVertexLast
indicates whether the implementation supports theVK_PROVOKING_VERTEX_MODE_LAST_VERTEX_EXT
provoking vertex mode for flat shading. -
transformFeedbackPreservesProvokingVertex
indicates that the order of vertices within each primitive written by transform feedback will preserve the provoking vertex. This does not apply to triangle fan primitives whentransformFeedbackPreservesTriangleFanProvokingVertex
isVK_FALSE
.transformFeedbackPreservesProvokingVertex
must beVK_FALSE
when theVK_EXT_transform_feedback
extension is not supported.
If the VkPhysicalDeviceProvokingVertexFeaturesEXT
structure is included in the pNext
chain of the
VkPhysicalDeviceFeatures2 structure passed to
vkGetPhysicalDeviceFeatures2, it is filled in to indicate whether each
corresponding feature is supported.
VkPhysicalDeviceProvokingVertexFeaturesEXT
can also be used in the pNext
chain of
VkDeviceCreateInfo to selectively enable these features.
When VkPhysicalDeviceProvokingVertexFeaturesEXT
is in the pNext
chain of VkDeviceCreateInfo but the transformFeedback
feature is not enabled, the value of
transformFeedbackPreservesProvokingVertex
is ignored.
