cmdDrawMeshTasksNV :: forall io. MonadIO io => CommandBuffer -> ("taskCount" ::: Word32) -> ("firstTask" ::: Word32) -> io () Source #
vkCmdDrawMeshTasksNV - Draw mesh task work items
Parameters
commandBuffer
is the command buffer into which the command will be recorded.
taskCount
is the number of local workgroups to dispatch in the X dimension. Y and Z dimension are implicitly set to one.firstTask
is the X component of the first workgroup ID.
Description
When the command is executed, a global workgroup consisting of
taskCount
local workgroups is assembled.

vkCmdDrawMeshTasksIndirectNV - Issue an indirect mesh tasks draw into a command buffer
Parameters
commandBuffer
is the command buffer into which the command is recorded.
buffer
is the buffer containing draw parameters.offset
is the byte offset intobuffer
where parameters begin.drawCount
is the number of draws to execute, and can be zero.stride
is the byte stride between successive sets of draw parameters.
Description
cmdDrawMeshTasksIndirectNV
behaves similarly to cmdDrawMeshTasksNV
except that the parameters are read by the device from a buffer during
execution. drawCount
draws are executed by the command, with
parameters taken from buffer
starting at offset
and increasing by
stride
bytes for each successive draw. The parameters of each draw are
encoded in an array of DrawMeshTasksIndirectCommandNV
structures. If
drawCount
is less than or equal to one, stride
is ignored.

Parameters
commandBuffer
is the command buffer into which the command is recorded.
buffer
is the buffer containing draw parameters.offset
is the byte offset intobuffer
where parameters begin.countBuffer
is the buffer containing the draw count.countBufferOffset
is the byte offset intocountBuffer

is the byte stride between successive sets of draw parameters.
Description
cmdDrawMeshTasksIndirectCountNV
behaves similarly to
cmdDrawMeshTasksIndirectNV
except that the draw count is read by the
device from a buffer during execution. The command will read an unsigned
32-bit integer from countBuffer
located at countBufferOffset
and use
this as the draw count.
