vkCmdDrawIndirectCount - Draw primitives with indirect parameters and draw count
Description
cmdDrawIndirectCount
behaves similarly to
cmdDrawIndirect
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.
