Description

One of the states that contributes to the combinatorial explosion of pipeline state objects that need to be created, is the vertex input binding and attribute descriptions. By allowing them to be dynamic applications may reduce the number of pipeline objects they need to create.

This extension adds dynamic state support for what is normally static state in PipelineVertexInputStateCreateInfo.

Members

This structure describes the following feature:

Description

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

VkVertexInputBindingDescription2EXT - Structure specifying the extended vertex input binding description

Valid Usage

binding must be less than PhysicalDeviceLimits::maxVertexInputBindings

stride must be less than or equal to PhysicalDeviceLimits::maxVertexInputBindingStride
If the vertexAttributeInstanceRateZeroDivisor feature is not enabled, divisor must not be 0
If the vertexAttributeInstanceRateDivisor feature is not enabled, divisor must be 1
divisor must be a value between 0 and PhysicalDeviceVertexAttributeDivisorPropertiesEXT::maxVertexAttribDivisor, inclusive
If divisor is not 1 then inputRate must be of type VERTEX_INPUT_RATE_INSTANCE

Valid Usage (Implicit)

sType must be STRUCTURE_TYPE_VERTEX_INPUT_BINDING_DESCRIPTION_2_EXT

inputRate must be a valid VertexInputRate value

binding :: Word32
binding is the binding number that this structure describes.
stride :: Word32
stride is the distance in bytes between two consecutive elements within the buffer.
inputRate :: VertexInputRate
inputRate is a VertexInputRate value specifying whether vertex attribute addressing is a function of the vertex index or of the instance index.
divisor :: Word32
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 set to a value other than 1 if the vertexAttributeInstanceRateDivisor 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 of divisor is implementation-dependent and can be queried using PhysicalDeviceVertexAttributeDivisorPropertiesEXT::maxVertexAttribDivisor. A value of 0 can be used for the divisor if the vertexAttributeInstanceRateZeroDivisor feature is enabled. In this case, the same vertex attribute will be applied to all instances.
