vkCmdSetViewportWScalingEnableNV

Specify the viewport W scaling enable state dynamically for a command buffer
primary / secondary
both
graphics
state

To dynamically set the viewportWScalingEnable state, call:

void vkCmdSetViewportWScalingEnableNV(
    VkCommandBuffer commandBuffer,
    VkBool32 viewportWScalingEnable);
  • commandBuffer is the command buffer into which the command will be recorded.
  • viewportWScalingEnable specifies the viewportWScalingEnable state.

This command sets the viewportWScalingEnable state for subsequent drawing commands when drawing using shader objects, or when the graphics pipeline is created with VK_DYNAMIC_STATE_VIEWPORT_W_SCALING_ENABLE_NV set in VkPipelineDynamicStateCreateInfo::pDynamicStates. Otherwise, this state is specified by the VkPipelineViewportWScalingStateCreateInfoNV::viewportWScalingEnable value used to create the currently active pipeline.

Valid Usage

VUID-vkCmdSetViewportWScalingEnableNV-None-09423

At least one of the following must be true:

Valid Usage (Implicit)

VUID-vkCmdSetViewportWScalingEnableNV-commandBuffer-parameter

commandBuffer must be a valid VkCommandBuffer handle

VUID-vkCmdSetViewportWScalingEnableNV-commandBuffer-recording

commandBuffer must be in the recording state

VUID-vkCmdSetViewportWScalingEnableNV-commandBuffer-cmdpool

The VkCommandPool that commandBuffer was allocated from must support graphics operations

VUID-vkCmdSetViewportWScalingEnableNV-videocoding

This command must only be called outside of a video coding scope

Host Synchronization

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