vkCmdCopyMicromapEXT
To copy a micromap call:
void vkCmdCopyMicromapEXT(
VkCommandBuffer commandBuffer,
const VkCopyMicromapInfoEXT* pInfo);
commandBuffer
is the command buffer into which the command will be recorded.pInfo
is a pointer to a VkCopyMicromapInfoEXT structure defining the copy operation.
This command copies the pInfo→src
micromap to the pInfo→dst
micromap in the manner specified by pInfo→mode
.
Accesses to pInfo→src
and pInfo→dst
must be
synchronized with the
VK_PIPELINE_STAGE_2_MICROMAP_BUILD_BIT_EXT
pipeline stage and an
access type of
VK_ACCESS_2_MICROMAP_READ_BIT_EXT
or
VK_ACCESS_2_MICROMAP_WRITE_BIT_EXT
as appropriate.
Valid Usage
VUID-vkCmdCopyMicromapEXT-buffer-07529
The buffer
used to create pInfo→src
must be bound to
device memory
VUID-vkCmdCopyMicromapEXT-buffer-07530
The buffer
used to create pInfo→dst
must be bound to
device memory
Valid Usage (Implicit)
VUID-vkCmdCopyMicromapEXT-commandBuffer-parameter
commandBuffer
must be a valid VkCommandBuffer handle
VUID-vkCmdCopyMicromapEXT-pInfo-parameter
pInfo
must be a valid pointer to a valid VkCopyMicromapInfoEXT structure
VUID-vkCmdCopyMicromapEXT-commandBuffer-recording
commandBuffer
must be in the recording state
VUID-vkCmdCopyMicromapEXT-commandBuffer-cmdpool
The VkCommandPool
that commandBuffer
was allocated from must support compute operations
VUID-vkCmdCopyMicromapEXT-renderpass
This command must only be called outside of a render pass instance
VUID-vkCmdCopyMicromapEXT-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 ::
