cmdSetViewportWScalingNV :: forall io. MonadIO io => CommandBuffer -> ("firstViewport" ::: Word32) -> ("viewportWScalings" ::: Vector ViewportWScalingNV) -> io ()

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 ViewportWScalingNV 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

• 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

Constructors

PipelineViewportWScalingStateCreateInfoNV

Fields

• viewportWScalingEnable :: Bool

  viewportWScalingEnable controls whether viewport W scaling is enabled.

• viewportWScalings :: Either Word32 (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.
