vkCmdSetProvokingVertexModeEXT
To dynamically set the
provokingVertexMode
state, call:
void vkCmdSetProvokingVertexModeEXT(
VkCommandBuffer commandBuffer,
VkProvokingVertexModeEXT provokingVertexMode);
commandBuffer
is the command buffer into which the command will be recorded.provokingVertexMode
specifies theprovokingVertexMode
state.
This command sets the provokingVertexMode
state for subsequent drawing
commands
when drawing using shader objects, or
when the graphics pipeline is created with
VK_DYNAMIC_STATE_PROVOKING_VERTEX_MODE_EXT
set in
VkPipelineDynamicStateCreateInfo::pDynamicStates
.
Otherwise, this state is specified by the
VkPipelineRasterizationProvokingVertexStateCreateInfoEXT::provokingVertexMode
value used to create the currently active pipeline.
Valid Usage
VUID-vkCmdSetProvokingVertexModeEXT-None-09423
At least one of the following must be true:
VUID-vkCmdSetProvokingVertexModeEXT-provokingVertexMode-07447
If provokingVertexMode
is
VK_PROVOKING_VERTEX_MODE_LAST_VERTEX_EXT
, then the
provokingVertexLast
feature
must be enabled
Valid Usage (Implicit)
VUID-vkCmdSetProvokingVertexModeEXT-commandBuffer-parameter
commandBuffer
must be a valid VkCommandBuffer handle
VUID-vkCmdSetProvokingVertexModeEXT-provokingVertexMode-parameter
provokingVertexMode
must be a valid VkProvokingVertexModeEXT value
VUID-vkCmdSetProvokingVertexModeEXT-commandBuffer-recording
commandBuffer
must be in the recording state
VUID-vkCmdSetProvokingVertexModeEXT-commandBuffer-cmdpool
The VkCommandPool
that commandBuffer
was allocated from must support graphics operations
VUID-vkCmdSetProvokingVertexModeEXT-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
thatcommandBuffer
was allocated from must be externally synchronized ::
