vkCmdSetViewportSwizzleNV

To dynamically set the viewport swizzle state, call:

void vkCmdSetViewportSwizzleNV(
    VkCommandBuffer commandBuffer,
    uint32_t firstViewport,
    uint32_t viewportCount,
    const VkViewportSwizzleNV* pViewportSwizzles);

• 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.
• pViewportSwizzles is a pointer to an array of VkViewportSwizzleNV structures specifying viewport swizzles.

This command sets the viewport swizzle state for subsequent drawing commands when drawing using shader objects, or when the graphics pipeline is created with VK_DYNAMIC_STATE_VIEWPORT_SWIZZLE_NV set in VkPipelineDynamicStateCreateInfo::pDynamicStates. Otherwise, this state is specified by the VkPipelineViewportSwizzleStateCreateInfoNV::viewportCount, and VkPipelineViewportSwizzleStateCreateInfoNV::pViewportSwizzles values used to create the currently active pipeline.
