vkCmdDrawIndirect - Issue an indirect draw into a command buffer.
|
|
|
|
C Specification

---------------
|

include::../protos/vkCmdDrawIndirect.txt[]
|

Parameters
|
|
----------
|
|
|
|
pname:commandBuffer::
|
|
Specifies the command buffer into which to insert the draw command.
|
|
|
|
pname:buffer::
|
|
Specifies a handle of a buffer object containing parameters forming individual draw commands.
|
|
|
|
pname:offset::
|
|
Specifies offset, in bytes, within the buffer object represented by pname:buffer at which the drawing command parameters begin.
|
|
|
|
pname:drawCount::
|
|
Specifies the number of indirect draws to consume from the specified
|
|
memory object.
|
|
|
|
pname:stride::
|
|
Specifies the distance, in bytes, between the start of each indirect draw in the memory object. This parameter
|
|
may be zero to indicate that the array of indirect draw commands is tightly packed.
|
|
|
|
Description
|
|
-----------
|
|
|
|
fname:vkCmdDrawIndirect issues an indirect draw into a command bufer. Each
|
|
indirect command consumes pname:drawCount structures, stored at pname:offset
|
|
bytes into the buffer object whose handle is specified in pname:buffer.
|
|
The beginning of each structure is pname:stride bytes from the previous.
|
|
The data structures have the a layout in memory which may be represented by
|
|
the the slink:VkDrawIndirectCommand structure, the definition of which is:
|
|
|
|
include::../structs/VkDrawIndirectCommand.txt[]
|
|
|
|
If pname:stride is zero, the array of slink:VkDrawIndirectCommand structures is
|
|
assumed to be tightly packed.

Notes
|
|
-----
|
|
|
|
Although fname:vkCmdDrawIndirect does not generate errors or return a value, enabled
|
|
validation layers may detect possible error conditions or potentially undefined
|
|
behavior and report this via some other means.
