## Parameters

• commandBuffer is the command buffer into which the command is recorded.

• buffer is the buffer containing draw parameters.

• offset is the byte offset into buffer where parameters begin.

• countBuffer is the buffer containing the draw count.

• countBufferOffset is the byte offset into countBuffer where the draw count begins.

• maxDrawCount specifies the maximum number of draws that will be executed. The actual number of executed draw calls is the minimum of the count specified in countBuffer and maxDrawCount.

• stride is the byte stride between successive sets of draw parameters.

## Description

vkCmdDrawIndexedIndirectCount behaves similarly to vkCmdDrawIndexedIndirect 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.
