vkCmdSetViewportWScalingEnableNV(3)

C Specification

To dynamically set the viewportWScalingEnable state, call:

// Provided by VK_EXT_extended_dynamic_state3, VK_EXT_shader_object
void vkCmdSetViewportWScalingEnableNV(
    VkCommandBuffer                             commandBuffer,
    VkBool32                                    viewportWScalingEnable);

Parameters

commandBuffer is the command buffer into which the command will be recorded.
viewportWScalingEnable specifies the viewportWScalingEnable state.

Description

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-08594
Either the extendedDynamicState3ViewportWScalingEnable feature or the shaderObject feature or both must be enabled

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
