= Drawing Commands
|
|
|
|
_Drawing commands_ (commands with ftext:Draw in the name) provoke work in a
|
|
graphics pipeline.
|
|
Drawing commands are recorded into a command buffer and when executed by a
|
|
queue, will produce work which executes according to the bound graphics
|
|
pipeline.
|
|
A graphics pipeline must: be bound to a command buffer before any drawing
|
|
commands are recorded in that command buffer.

Drawing can be achieved in two modes:
|
|
|
|
* <<drawing-mesh-shading,Programmable Mesh Shading>>, the mesh shader
|
|
assembles primitives, or
|
|
* <<drawing-primitive-shading,Programmable Primitive Shading>>, the input
|
|
primitives are assembled
|
|
|
|
as follows.
|
|
endif::VK_NV_mesh_shader[]
|
|
|
|
Each draw is made up of zero or more vertices and zero or more instances,
|
|
which are processed by the device and result in the assembly of primitives.
|
|
Primitives are assembled according to the pname:pInputAssemblyState member
|
|
of the sname:VkGraphicsPipelineCreateInfo structure, which is of type
|
|
sname:VkPipelineInputAssemblyStateCreateInfo:
|
|
|
|
include::../api/structs/VkPipelineInputAssemblyStateCreateInfo.txt[]
|
|
|
|
* pname:sType is the type of this structure.
|
|
* pname:pNext is `NULL` or a pointer to an extension-specific structure.
|
|
* pname:flags is reserved for future use.
|
|
* pname:topology is a elink:VkPrimitiveTopology defining the primitive
|
|
topology, as described below.
|
|
* pname:primitiveRestartEnable controls whether a special vertex index
|
|
value is treated as restarting the assembly of primitives.
|
|
This enable only applies to indexed draws (flink:vkCmdDrawIndexed and
|
|
flink:vkCmdDrawIndexedIndirect), and the special index value is either
|
|
0xFFFFFFFF when the pname:indexType parameter of
|
|
fname:vkCmdBindIndexBuffer is equal to ename:VK_INDEX_TYPE_UINT32, or
|
|
0xFFFF when pname:indexType is equal to ename:VK_INDEX_TYPE_UINT16.
|
|
Primitive restart is not allowed for "`list`" topologies.
|
|
|
|
Restarting the assembly of primitives discards the most recent index values
|
|
if those elements formed an incomplete primitive, and restarts the primitive
|
|
assembly using the subsequent indices, but only assembling the immediately
|
|
following element through the end of the originally specified elements.
|
|
The primitive restart index value comparison is performed before adding the
|
|
pname:vertexOffset value to the index value.

|
|
_Primitive topology_ determines how consecutive vertices are organized into
|
|
primitives, and determines the type of primitive that is used at the
|
|
beginning of the graphics pipeline.
|
|
The effective topology for later stages of the pipeline is altered by
|
|
tessellation or geometry shading (if either is in use) and depends on the
|
|
execution modes of those shaders.
|
|
ifdef::VK_NV_mesh_shader[]
|
|
In the case of mesh shading the only effective topology is defined by the
|
|
execution mode of the mesh shader.

|
|
Each primitive topology, and its construction from a list of vertices, is
|
|
summarized below with a supporting diagram.
|
|
In each diagram, the numbered points show the sequencing of vertices in
|
|
order within the vertex arrays; however the positions chosen are arbitrary
|
|
and for illustration only.
|
|
Vertices connected with solid lines belong to the main primitives.
|
|
In the primitive types with adjacency, the vertices connected by dashed
|
|
lines are the adjacent vertices that are accessible in a geometry shader.

|
|
=== Point Lists
|
|
|
|
A series of individual points are specified with pname:topology
|
|
ename:VK_PRIMITIVE_TOPOLOGY_POINT_LIST.
|
|
Each vertex defines a separate point.
|
|
|
|
.Point Lists

|
|
|
|
|
|
=== Line Lists
|
|
|
|
Lists of line segments, with each segment defined by a pair of vertices, are
|
|
specified with pname:topology ename:VK_PRIMITIVE_TOPOLOGY_LINE_LIST.
|
|
The first two vertices define the first segment, with subsequent pairs of
|
|
vertices each defining one more segment.
|
|
If the number of vertices is odd, then the last vertex is ignored.

=== Line Strips
|
|
|
|
A series of one or more connected line segments are specified with
|
|
pname:topology ename:VK_PRIMITIVE_TOPOLOGY_LINE_STRIP.
|
|
In this case, the first vertex specifies the first segment's start point
|
|
while the second vertex specifies the first segment's endpoint and the
|
|
second segment's start point.
|
|
In general, vertex [eq]#i# (for [eq]#i > 0#) specifies the beginning of the
|
|
[eq]##i##th segment and the end of the previous segment.
|
|
The last vertex specifies the end of the last segment.
|
|
If only one vertex is specified, then no primitive is generated.

=== Triangle Lists
|
|
|
|
Lists of separate triangles are specified with pname:topology
|
|
ename:VK_PRIMITIVE_TOPOLOGY_TRIANGLE_LIST.
|
|
In this case, vertices [eq]#3 i#, [eq]#3 i {plus} 1#, and [eq]#3 i {plus} 2#
|
|
(in that order) determine a triangle for each [eq]#i = 0, 1, ..., n-1#,
|
|
where there are [eq]#3 n {plus} k# vertices drawn.
|
|
[eq]#k# is either 0, 1, or 2; if [eq]#k# is not zero, the final [eq]#k#
|
|
vertices are ignored.

=== Triangle Strips
|
|
|
|
A triangle strip is a series of triangles connected along shared edges, and
|
|
is specified with pname:topology ename:VK_PRIMITIVE_TOPOLOGY_TRIANGLE_STRIP.
|
|
In this case, the first three vertices define the first triangle, and their
|
|
order is significant.
|
|
Each subsequent vertex defines a new triangle using that point along with
|
|
the last two vertices from the previous triangle.
|
|
If fewer than three vertices are specified, no primitive is produced.
|
|
The order of vertices in successive triangles changes as shown in the figure
|
|
below, so that all triangle faces have the same orientation.

=== Triangle Fans
|
|
|
|
A triangle fan is specified with pname:topology
|
|
ename:VK_PRIMITIVE_TOPOLOGY_TRIANGLE_FAN.
|
|
It is similar to a triangle strip, but changes the vertex replaced from the
|
|
previous triangle so that all triangles in the fan share a common vertex.

=== Line Lists With Adjacency
|
|
|
|
Lines with adjacency are specified with pname:topology
|
|
ename:VK_PRIMITIVE_TOPOLOGY_LINE_LIST_WITH_ADJACENCY, and are independent
|
|
line segments where each endpoint has a corresponding _adjacent_ vertex that
|
|
is accessible in a <<geometry,geometry shader>>.
|
|
If a geometry shader is not active, the adjacent vertices are ignored.
|
|
|
|
A line segment is drawn from vertex [eq]#4 i {plus} 1# to vertex [eq]#4 i
|
|
{plus} 2# for each [eq]#i = 0, 1, ..., n-1#, where there are [eq]#4 n {plus}
|
|
k# vertices.
|
|
[eq]#k# is either 0, 1, 2, or 3; if [eq]#k# is not zero, the final [eq]#k#
|
|
vertices are ignored.
|
|
For line segment [eq]#i#, vertices [eq]#4 i# and [eq]#4 i {plus} 3# vertices
|
|
are considered adjacent to vertices [eq]#4 i {plus} 1# and [eq]#4 i {plus}
|

|
line strips, except that each line segment has a pair of adjacent vertices
|
|
that are accessible in a geometry shader.
|
|
If a geometry shader is not active, the adjacent vertices are ignored.
|
|
|
|
A line segment is drawn from vertex [eq]#i {plus} 1# vertex to vertex [eq]#i
|

{plus} 2# for each [eq]#i = 0, 1, ..., n-1#, where there are [eq]#n {plus}
|
|
3# vertices.
|
|
If there are fewer than four vertices, all vertices are ignored.
|
|
For line segment [eq]#i#, vertices [eq]#i# and [eq]#i {plus} 3# are

|
considered adjacent to vertices [eq]#i {plus} 1# and [eq]#i {plus} 2#,

ename:VK_PRIMITIVE_TOPOLOGY_TRIANGLE_LIST_WITH_ADJACENCY, and are similar to
|
|
separate triangles except that each triangle edge has an adjacent vertex
|
|
that is accessible in a geometry shader.
|
|
If a geometry shader is not active, the adjacent vertices are ignored.
|
|
|
|
Vertices [eq]#6 i#, [eq]#6 i {plus} 2#, and [eq]#6 i {plus} 4# (in that
|
|
order) determine a triangle for each [eq]#i = 0, 1, ..., n-1#, where there
|

are [eq]#6 n+k# vertices.
|
|
[eq]#k# is either 0, 1, 2, 3, 4, or 5; if [eq]#k# is non-zero, the final

image::images/primitive_topology_triangle_strip_with_adjacency.svg[align="center",opts="{imageopts}"]
|
|
|
|
The table below illustrates the vertices and order used to draw each
|
|
triangle, and which vertices are considered adjacent to each edge of those
|
|
triangles.
|
|
Each triangle is drawn using the vertices whose numbers are in the *1st*,
|
|
*2nd*, and *3rd* columns under *Primitive Vertices*, in that order.
|
|
The vertices in the 1/2, 2/3, and 3/1 columns under *Adjacent Vertices* are
|
|
considered adjacent to the edges from the first to the second, from the
|
|
second to the third, and from the third to the first vertex of the triangle,
|
|
respectively.
|
|
The six rows correspond to six cases: the first and only triangle [eq]#(i =
|
|
0, n = 1)#, the first triangle of several [eq]#(i = 0, n > 0)#, _odd_ middle
|
|
triangles [eq]#(i = 1, 3, 5 ...)#, _even_ middle triangles [eq]#(i = 2, 4,
|
|
6, ...)#, and special cases for the last triangle, when [eq]#i# is either
|
|
even or odd.
|
|
For the purposes of this table, both the first vertex and first triangle are
|
|
numbered [eq]#0#.

|
|
=== Separate Patches
|
|
|
|
Separate patches are specified with pname:topology
|
|
ename:VK_PRIMITIVE_TOPOLOGY_PATCH_LIST.
|
|
A patch is an ordered collection of vertices used for
|
|
<<tessellation,primitive tessellation>>.
|
|
The vertices comprising a patch have no implied geometric ordering, and are
|
|
used by tessellation shaders and the fixed-function tessellator to generate
|
|
new point, line, or triangle primitives.
|
|
|
|
Each patch in the series has a fixed number of vertices, specified by the
|
|
pname:patchControlPoints member of the
|
|
slink:VkPipelineTessellationStateCreateInfo structure passed to
|
|
flink:vkCreateGraphicsPipelines.
|
|
Once assembled and vertex shaded, these patches are provided as input to the
|
|
tessellation control shader stage.
|
|
|
|
If the number of vertices in a patch is given by [eq]#v#, vertices [eq]#v
|
|
{times} i# through [eq]#v {times} i {plus} v - 1# (in that order) determine
|
|
a patch for each [eq]#i = 0, 1, ..., n-1#, where there are [eq]#v {times} n
|
|
{plus} k# vertices.
|
|
[eq]#k# is in the range [eq]#[0, v - 1]#; if [eq]#k# is not zero, the final
|
|
[eq]#k# vertices are ignored.

[[drawing-primitive-order]]

|
== Primitive Order
|
|
|
|
Primitives generated by <<drawing, drawing commands>> progress through the
|
|
stages of the <<synchronization-pipeline-stages-types, graphics pipeline>>
|
|
in _primitive order_.
|
|
Primitive order is initially determined in the following way:
|
|
|
|
. Submission order determines the initial ordering
|
|
. For indirect draw commands, the order in which accessed instances of the
|
|
slink:VkDrawIndirectCommand are stored in pname:buffer, from lower
|
|
indirect buffer addresses to higher addresses.
|
|
. If a draw command includes multiple instances, the order in which
|
|
instances are executed, from lower numbered instances to higher.
|
|
. The order in which primitives are specified by a draw command:
|
|
** For non-indexed draws, from vertices with a lower numbered
|
|
code:vertexIndex to a higher numbered code:vertexIndex.
|
|
** For indexed draws, vertices sourced from a lower index buffer addresses
|
|
to higher addresses.
|
|
ifdef::VK_NV_mesh_shader[]
|
|
** For draws using mesh shaders, the order is provided by <<mesh-ordering,
|
|
mesh shading>>.
|
|
endif::VK_NV_mesh_shader[]
|
|
|
|
Within this order implementations further sort primitives:
|
|
|
|
[start=5]
|
|
. If tessellation shading is active, by an implementation-dependent order
|
|
of new primitives generated by <<tessellation-primitive-order,
|
|
tessellation>>.
|
|
. If geometry shading is active, by the order new primitives are generated
|
|
by <<geometry-ordering, geometry shading>>.
|
|
. If the <<primsrast-polygonmode,polygon mode>> is not
|
|
ename:VK_POLYGON_MODE_FILL,
|
|
ifdef::VK_NV_fill_rectangle[]
|
|
or ename:VK_POLYGON_MODE_FILL_RECTANGLE_NV,
|
|
endif::VK_NV_fill_rectangle[]
|
|
by an implementation-dependent ordering of the new primitives generated
|
|
within the original primitive.
|
|
|
|
Primitive order is later used to define <<primrast-order, rasterization
|
|
order>>, which determines the order in which fragments output results to a
|
|
framebuffer.
|
|
|
|
|
|
[[drawing-primitive-shading]]
|
|
== Programmable Primitive Shading
|
|
|
|
Once primitives are assembled, they proceed to the vertex shading stage of
|
|
the pipeline.
|
|
If the draw includes multiple instances, then the set of primitives is sent
|
|
to the vertex shading stage multiple times, once for each instance.
|
|
|
|
It is implementation-dependent whether vertex shading occurs on vertices
|
|
that are discarded as part of incomplete primitives, but if it does occur
|
|
then it operates as if they were vertices in complete primitives and such
|
|
invocations can: have side effects.
|
|
|
|
Vertex shading receives two per-vertex inputs from the primitive assembly
|
|
stage - the code:vertexIndex and the code:instanceIndex.
|
|
How these values are generated is defined below, with each command.
|
|
|
|
Drawing commands fall roughly into two categories:
|
|
|
|
* Non-indexed drawing commands present a sequential code:vertexIndex to
|
|
the vertex shader.
|
|
The sequential index is generated automatically by the device (see
|
|
<<fxvertex,Fixed-Function Vertex Processing>> for details on both
|
|
specifying the vertex attributes indexed by code:vertexIndex, as well as
|
|
binding vertex buffers containing those attributes to a command buffer).
|
|

=== Drawing Transform Feedback
|
|
|
|
It is possible to draw vertex data that was previously captured during
|
|
active <<vertexpostproc-transform-feedback,transform feedback>> by binding
|
|
one or more of the transform feedback buffers as vertex buffers.
|
|
A pipeline barrier is required between using the buffers as transform
|
|
feedback buffers and vertex buffers to ensure all writes to the transform
|
|
feedback buffers are visible when the data is read as vertex attributes.
|
|
The source access is ename:VK_ACCESS_TRANSFORM_FEEDBACK_WRITE_BIT_EXT and
|
|
the destination access is ename:VK_ACCESS_VERTEX_ATTRIBUTE_READ_BIT for the
|
|
pipeline stages ename:VK_PIPELINE_STAGE_TRANSFORM_FEEDBACK_BIT_EXT and
|
|
ename:VK_PIPELINE_STAGE_VERTEX_INPUT_BIT respectively.
|
|
The value written to the counter buffer by
|
|
flink:vkCmdEndTransformFeedbackEXT can: be used to determine the vertex
|
|
count for the draw.
|
|
A pipeline barrier is required between using the counter buffer for
|
|
fname:vkCmdEndTransformFeedbackEXT and fname:vkCmdDrawIndirectByteCountEXT
|
|
where the source access is
|
|
ename:VK_ACCESS_TRANSFORM_FEEDBACK_COUNTER_WRITE_BIT_EXT and the destination
|
|
access is ename:VK_ACCESS_INDIRECT_COMMAND_READ_BIT for the pipeline stages
|
|
ename:VK_PIPELINE_STAGE_TRANSFORM_FEEDBACK_BIT_EXT and
|
|
ename:VK_PIPELINE_STAGE_DRAW_INDIRECT_BIT respectively.

|
|
|

To record a non-indexed draw call, where the vertex count is based on a byte
|
|
count read from a buffer and the passed in vertex stride parameter, call:
|
|
|
|
include::../api/protos/vkCmdDrawIndirectByteCountEXT.txt[]
|
|
|
|
* pname:commandBuffer is the command buffer into which the command is
|
|
recorded.
|
|
* pname:instanceCount is the number of instances to draw.
|
|
* pname:firstInstance is the instance ID of the first instance to draw.
|
|
* pname:counterBuffer is the buffer handle from where the byte count is
|
|
read.
|
|
* pname:counterBufferOffset is the offset into the buffer used to read the
|
|
byte count, which is used to calculate the vertex count for this draw
|
|
call.
|
|
* pname:counterOffset is subtracted from the byte count read from the
|
|
pname:counterBuffer at the pname:counterBufferOffset
|
|
* pname:vertexStride is the stride in bytes between each element of the
|
|
vertex data that is used to calculate the vertex count from the counter
|
|
value.
|
|
This value is typically the same value that was used in the graphics
|
|
pipeline state when the transform feedback was captured as the
|
|
code:XfbStride.
|
|
|
|
When the command is executed, primitives are assembled in the same way as
|
|
done with flink:vkCmdDraw except the pname:vertexCount is calculated based
|
|
on the byte count read from pname:counterBuffer at offset
|
|
pname:counterBufferOffset.
|
|
The assembled primitives execute the bound graphics pipeline.
|
|
|
|
The effective pname:vertexCount is calculated as follows:
|
|
|
|
[source,c]
|
|
---------------------------------------------------
|
|
const uint32_t * counterBufferPtr = (const uint8_t *)counterBuffer.address + counterBufferOffset;
|
|
vertexCount = floor(max(0, (*counterBufferPtr - counterOffset)) / vertexStride);
|
|
---------------------------------------------------
|
|
|
|
The effective pname:firstVertex is zero.

== Conditional Rendering
|
|
Certain rendering commands can: be executed conditionally based on a value
|
|
in buffer memory.
|
|
These rendering commands are limited to <<drawing,drawing commands>>,
|
|
<<dispatch,dispatching commands>>, and clearing attachments with
|
|
flink:vkCmdClearAttachments within a conditional rendering block which is
|
|
defined by commands flink:vkCmdBeginConditionalRenderingEXT and
|
|
flink:vkCmdEndConditionalRenderingEXT.
|
|
Other rendering commands remain unaffected by conditional rendering.
|
|
|
|
[[active-conditional-rendering]]
|
|
After beginning conditional rendering, it is considered _active_ within the
|
|
command buffer it was called until it is ended with
|
|
flink:vkCmdEndConditionalRenderingEXT.
|
|
|
|
Conditional rendering must: begin and end in the same command buffer.
|
|
When conditional rendering is active, a primary command buffer can: execute
|
|
secondary command buffers if the
|
|
<<features-features-inheritedConditionalRendering, inherited conditional
|
|
rendering>> feature is enabled.
|
|
For a secondary command buffer to be executed while conditional rendering is
|
|
active in the primary command buffer, it must: set the
|
|
pname:conditionalRenderingEnable flag of
|
|
slink:VkCommandBufferInheritanceConditionalRenderingInfoEXT, as described in
|
|
the <<commandbuffers-recording, Command Buffer Recording>> section.
|
|
|
|
Conditional rendering must: also either begin and end inside the same
|
|
subpass of a render pass instance, or must: both begin and end outside of a
|
|
render pass instance (i.e. contain entire render pass instances).

|
|
|
|
* pname:sType is the type of this structure.
|
|
* pname:pNext is `NULL` or a pointer to an extension-specific structure.
|
|
* pname:buffer is a buffer containing the predicate for conditional
|
|
rendering.
|
|
* pname:offset is the byte offset into pname:buffer where the predicate is
|
|
located.
|
|
* pname:flags is a bitmask of elink:VkConditionalRenderingFlagsEXT
|
|
specifying the behavior of conditional rendering.
|
|
|
|
If the 32-bit value at pname:offset in pname:buffer memory is zero, then the
|
|
rendering commands are discarded, otherwise they are executed as normal.
|
|
If the value of the predicate in buffer memory changes while conditional
|
|
rendering is active, the rendering commands may: be discarded in an
|
|
implementation-dependent way.
|
|
Some implementations may latch the value of the predicate upon beginning
|
|
conditional rendering while others may read it before every rendering
|
|
command.
