cmdSetViewportWScalingNV Source #

Arguments

:: forall io. MonadIO io
=> CommandBuffer	`commandBuffer` is the command buffer into which the command will be recorded.
-> ("firstViewport" ::: Word32)	`firstViewport` is the index of the first viewport whose parameters are updated by the command.
-> ("viewportWScalings" ::: Vector ViewportWScalingNV)	`pViewportWScalings` is a pointer to an array of `ViewportWScalingNV` structures specifying viewport parameters.
-> io ()

vkCmdSetViewportWScalingNV - Set the viewport W scaling on a command buffer

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

firstViewport must be less than PhysicalDeviceLimits::maxViewports

The sum of firstViewport and viewportCount must be between 1 and PhysicalDeviceLimits::maxViewports, inclusive

Valid Usage (Implicit)

commandBuffer must be a valid CommandBuffer handle

pViewportWScalings must be a valid pointer to an array of viewportCount ViewportWScalingNV structures
commandBuffer must be in the recording state
The CommandPool 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 CommandPool that commandBuffer was allocated from must be externally synchronized

data PipelineViewportWScalingStateCreateInfoNV Source #

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

Valid Usage (Implicit)

viewportWScalingEnable :: Bool
viewportWScalingEnable controls whether viewport W scaling is enabled.
viewportCount :: 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.
viewportCount must be greater than 0
viewportWScalings :: Vector ViewportWScalingNV
pViewportWScalings is a pointer to an array of ViewportWScalingNV structures defining the W scaling parameters for the corresponding viewports. If the viewport W scaling state is dynamic, this member is ignored.
