C Specification
If the bound pipeline state object was not created with the
VK_DYNAMIC_STATE_VIEWPORT_W_SCALING_NV
dynamic state enabled, viewport
W scaling parameters are specified using the pViewportWScalings
member of VkPipelineViewportWScalingStateCreateInfoNV in the pipeline
state object.
If the pipeline state object was created with the
VK_DYNAMIC_STATE_VIEWPORT_W_SCALING_NV
dynamic state enabled, the
viewport transformation parameters are dynamically set and changed with the
command:
void vkCmdSetViewportWScalingNV(
VkCommandBuffer commandBuffer,
uint32_t firstViewport,
uint32_t viewportCount,
const VkViewportWScalingNV* pViewportWScalings);
Parameters
-
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.
Description
The viewport parameters taken from element i of
pViewportWScalings
replace the current state for the viewport index
firstViewport
+ i, for i in [0,
viewportCount
).
