vkCmdSetViewportSwizzleNV
To dynamically set the viewport swizzle state, call:
void vkCmdSetViewportSwizzleNV(
VkCommandBuffer commandBuffer,
uint32_t firstViewport,
uint32_t viewportCount,
const VkViewportSwizzleNV* pViewportSwizzles);
commandBufferis the command buffer into which the command will be recorded.firstViewportis the index of the first viewport whose parameters are updated by the command.viewportCountis the number of viewports whose parameters are updated by the command.pViewportSwizzlesis 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.
