vkCmdSetViewportWScalingNV

To dynamically set the viewport W scaling parameters, call:

void vkCmdSetViewportWScalingNV(
    VkCommandBuffer commandBuffer,
    uint32_t firstViewport,
    uint32_t viewportCount,
    const VkViewportWScalingNV* pViewportWScalings);

• 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.

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

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