vkCmdSetPrimitiveTopology
To dynamically set primitive topology, call:
void vkCmdSetPrimitiveTopologyEXT(
VkCommandBuffer commandBuffer,
VkPrimitiveTopology primitiveTopology);
commandBuffer
is the command buffer into which the command will be recorded.primitiveTopology
specifies the primitive topology to use for drawing.
This command sets the primitive topology for subsequent drawing commands
when drawing using shader objects, or
when the graphics pipeline is created with
VK_DYNAMIC_STATE_PRIMITIVE_TOPOLOGY
set in
VkPipelineDynamicStateCreateInfo::pDynamicStates
.
Otherwise, this state is specified by the
VkPipelineInputAssemblyStateCreateInfo::topology
value used to
create the currently active pipeline.
Valid Usage
VUID-vkCmdSetPrimitiveTopology-None-08971
At least one of the following must be true:
Valid Usage (Implicit)
VUID-vkCmdSetPrimitiveTopology-commandBuffer-parameter
commandBuffer
must be a valid VkCommandBuffer handle
VUID-vkCmdSetPrimitiveTopology-primitiveTopology-parameter
primitiveTopology
must be a valid VkPrimitiveTopology value
VUID-vkCmdSetPrimitiveTopology-commandBuffer-recording
commandBuffer
must be in the recording state
VUID-vkCmdSetPrimitiveTopology-commandBuffer-cmdpool
The VkCommandPool
that commandBuffer
was allocated from must support graphics operations
VUID-vkCmdSetPrimitiveTopology-videocoding
This command must only be called outside of a video coding scope
Host Synchronization
