vkCmdBindTransformFeedbackBuffersEXT - Bind transform feedback buffers to a command buffer

Parameters

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

• firstBinding is the index of the first transform feedback binding whose state is updated by the command.
• bindingCount is the number of transform feedback bindings whose state is updated by the command.
• pBuffers is a pointer to an array of buffer handles.
• pOffsets is a pointer to an array of buffer offsets.
• pSizes is an optional array of buffer sizes, specifying the maximum number of bytes to capture to the corresponding transform feedback buffer. If pSizes is NULL, or the value of the pSizes array element is WHOLE_SIZE, then the maximum bytes captured will be the size of the corresponding buffer minus the buffer offset.

Description

The values taken from elements i of pBuffers, pOffsets and pSizes replace the current state for the transform feedback binding firstBinding + i, for i in [0, bindingCount). The transform feedback binding is updated to start at the offset indicated by pOffsets[i] from the start of the buffer pBuffers[i].

vkCmdBeginTransformFeedbackEXT - Make transform feedback active in the command buffer

Parameters

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

• firstCounterBuffer is the index of the first transform feedback buffer corresponding to pCounterBuffers[0] and pCounterBufferOffsets[0].
• counterBufferCount is the size of the pCounterBuffers and pCounterBufferOffsets arrays.
• pCounterBuffers is an optional array of buffer handles to the counter buffers which contain a 4 byte integer value representing the byte offset from the start of the corresponding transform feedback buffer from where to start capturing vertex data. If the byte offset stored to the counter buffer location was done using cmdEndTransformFeedbackEXT it can be used to resume transform feedback from the previous location. If pCounterBuffers is NULL, then transform feedback will start capturing vertex data to byte offset zero in all bound transform feedback buffers. For each element of pCounterBuffers that is NULL_HANDLE, transform feedback will start capturing vertex data to byte zero in the corresponding bound transform feedback buffer.
• pCounterBufferOffsets is an optional array of offsets within each of the pCounterBuffers where the counter values were previously written. The location in each counter buffer at these offsets must be large enough to contain 4 bytes of data. This data is the number of bytes captured by the previous transform feedback to this buffer. If pCounterBufferOffsets is NULL, then it is assumed the offsets are zero.

Description

The active transform feedback buffers will capture primitives emitted from the corresponding XfbBuffer in the bound graphics pipeline. Any XfbBuffer emitted that does not output to an active transform feedback buffer will not be captured.

Valid Usage

• PhysicalDeviceTransformFeedbackFeaturesEXT::transformFeedback must be enabled

• Transform feedback must not be active
• firstCounterBuffer must be less than PhysicalDeviceTransformFeedbackPropertiesEXT::maxTransformFeedbackBuffers
• The sum of firstCounterBuffer and counterBufferCount must be less than or equal to PhysicalDeviceTransformFeedbackPropertiesEXT::maxTransformFeedbackBuffers

vkCmdDrawIndirectByteCountEXT - Draw primitives where the vertex count is derived from the counter byte value in the counter buffer

Parameters

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

• instanceCount is the number of instances to draw.
• firstInstance is the instance ID of the first instance to draw.
• counterBuffer is the buffer handle from where the byte count is read.
• 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.
• counterOffset is subtracted from the byte count read from the counterBuffer at the counterBufferOffset
• 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 XfbStride.

Description

When the command is executed, primitives are assembled in the same way as done with cmdDraw except the vertexCount is calculated based on the byte count read from counterBuffer at offset counterBufferOffset. The assembled primitives execute the bound graphics pipeline.

The effective vertexCount is calculated as follows:

const uint32_t * counterBufferPtr = (const uint8_t *)counterBuffer.address + counterBufferOffset;
vertexCount = floor(max(0, (*counterBufferPtr - counterOffset)) / vertexStride);

The effective firstVertex is zero.
