pattern VK_DYNAMIC_STATE_VIEWPORT_W_SCALING_NV :: VkDynamicState Source #

VK_DYNAMIC_STATE_VIEWPORT_W_SCALING_NV specifies that the pViewportScalings state in VkPipelineViewportWScalingStateCreateInfoNV will be ignored and must be set dynamically with vkCmdSetViewportWScalingNV before any draws are performed with a pipeline state with VkPipelineViewportWScalingStateCreateInfo member viewportScalingEnable set to VK_TRUE

vkCmdSetViewportWScalingNV - Set the viewport W scaling on a command buffer

Parameters

commandBuffer is the command buffer into which the command will be recorded.

firstViewport is the index of the first viewport whose parameters are updated by the command.
viewportCount is the number of viewports whose parameters are updated by the command.
pViewportWScalings is a pointer to an array of VkViewportWScalingNV structures specifying viewport parameters.

Description

The viewport parameters taken from element i of pViewportWScalings replace the current state for the viewport index firstViewport + i, for i in [0, viewportCount).

Valid Usage

The bound graphics pipeline must have been created with the VK_DYNAMIC_STATE_VIEWPORT_W_SCALING_NV dynamic state enabled

firstViewport must be less than VkPhysicalDeviceLimits::maxViewports
The sum of firstViewport and viewportCount must be between 1 and VkPhysicalDeviceLimits::maxViewports, inclusive

Valid Usage (Implicit)

commandBuffer must be a valid VkCommandBuffer handle

pViewportWScalings must be a valid pointer to an array of viewportCount VkViewportWScalingNV structures
commandBuffer must be in the recording state
The VkCommandPool that commandBuffer was allocated from must support graphics operations
viewportCount must be greater than 0

Host Synchronization

Host access to commandBuffer must be externally synchronized

Host access to the VkCommandPool that commandBuffer was allocated from must be externally synchronized

data VkPipelineViewportWScalingStateCreateInfoNV Source #

VkPipelineViewportWScalingStateCreateInfoNV - Structure specifying parameters of a newly created pipeline viewport W scaling state

Valid Usage (Implicit)

sType must be VK_STRUCTURE_TYPE_PIPELINE_VIEWPORT_W_SCALING_STATE_CREATE_INFO_NV

viewportCount must be greater than 0

vkSType :: VkStructureType
sType is the type of this structure.
vkPNext :: Ptr ()
pNext is NULL or a pointer to an extension-specific structure.
vkViewportWScalingEnable :: VkBool32
viewportWScalingEnable controls whether viewport W scaling is enabled.
vkViewportCount :: Word32
viewportCount is the number of viewports used by W scaling, and must match the number of viewports in the pipeline if viewport W scaling is enabled.
vkPViewportWScalings :: Ptr VkViewportWScalingNV
pViewportWScalings is a pointer to an array of VkViewportWScalingNV structures, which define the W scaling parameters for the corresponding viewport. If the viewport W scaling state is dynamic, this member is ignored.
