VkVertexInputBindingDescription2EXT
Structure specifying the extended vertex input binding description
The VkVertexInputBindingDescription2EXT
structure is defined as:
typedef struct VkVertexInputBindingDescription2EXT {
VkStructureType sType;
void* pNext;
uint32_t binding;
uint32_t stride;
VkVertexInputRate inputRate;
uint32_t divisor;
} VkVertexInputBindingDescription2EXT;
sType
is a VkStructureType value identifying this structure.pNext
isNULL
or a pointer to a structure extending this structure.binding
is the binding number that this structure describes.stride
is the byte stride between consecutive elements within the buffer.inputRate
is a VkVertexInputRate value specifying whether vertex attribute addressing is a function of the vertex index or of the instance index.divisor
is the number of successive instances that will use the same value of the vertex attribute when instanced rendering is enabled. This member can be a value other than1
if thevertexAttributeInstanceRateDivisor
feature is enabled. For example, if the divisor is N, the same vertex attribute will be applied to N successive instances before moving on to the next vertex attribute. The maximum value ofdivisor
is implementation-dependent and can be queried usingVkPhysicalDeviceVertexAttributeDivisorPropertiesEXT
::maxVertexAttribDivisor
. A value of0
can be used for the divisor if thevertexAttributeInstanceRateZeroDivisor
feature is enabled. In this case, the same vertex attribute will be applied to all instances.
Valid Usage

binding
must be less than
VkPhysicalDeviceLimits
::maxVertexInputBindings
VUID-VkVertexInputBindingDescription2EXT-stride-04797
stride
must be less than or equal to

If the vertexAttributeInstanceRateZeroDivisor
feature is not enabled,
divisor
must not be 0

If the vertexAttributeInstanceRateDivisor
feature is not enabled,
divisor
must be 1
VUID-VkVertexInputBindingDescription2EXT-divisor-06226
divisor
must be a value between 0
and
VkPhysicalDeviceVertexAttributeDivisorPropertiesEXT
