The extension name.

The extension specification version.

Extends VkStructureType.

See CmdSetDepthBiasEnable.

Parameters

commandBuffer:VkCommandBuffer

the command buffer into which the command will be recorded.

depthBiasEnable:boolean

controls whether to bias fragment depth values.

Select which logical operation to apply for blend state dynamically for a command buffer.

C Specification

To dynamically set the logical operation to apply for blend state, call:

void vkCmdSetLogicOpEXT(
    VkCommandBuffer                             commandBuffer,
    VkLogicOp                                   logicOp);

Description

This command sets the logical operation for blend state for subsequent drawing commands when drawing using shader objects, or when the graphics pipeline is created with DYNAMIC_STATE_LOGIC_OP_EXT set in VkPipelineDynamicStateCreateInfo::pDynamicStates. Otherwise, this state is specified by the VkPipelineColorBlendStateCreateInfo::logicOp value used to create the currently active pipeline.

Valid Usage

• Either the extendedDynamicState2LogicOp feature or the shaderObject feature or both must be enabled

Valid Usage (Implicit)

• commandBuffer must be a valid VkCommandBuffer handle
• logicOp must be a valid VkLogicOp value
• commandBuffer must be in the recording state
• The VkCommandPool that commandBuffer was allocated from must support graphics operations
• This command must only be called outside of a video coding scope

Host Synchronization

• Host access to commandBuffer must be externally synchronized
• Host access to the VkCommandPool that commandBuffer was allocated from must be externally synchronized

Command Properties

Parameters

commandBuffer:VkCommandBuffer

the command buffer into which the command will be recorded.

logicOp:int

specifies the logical operation to apply for blend state.

Specify the number of control points per patch dynamically for a command buffer.

C Specification

To dynamically set the number of control points per patch, call:

void vkCmdSetPatchControlPointsEXT(
    VkCommandBuffer                             commandBuffer,
    uint32_t                                    patchControlPoints);

Description

This command sets the number of control points per patch for subsequent drawing commands when drawing using shader objects, or when the graphics pipeline is created with DYNAMIC_STATE_PATCH_CONTROL_POINTS_EXT set in VkPipelineDynamicStateCreateInfo::pDynamicStates. Otherwise, this state is specified by the VkPipelineTessellationStateCreateInfo::patchControlPoints value used to create the currently active pipeline.

Valid Usage

• Either the extendedDynamicState2PatchControlPoints feature or the shaderObject feature or both must be enabled
• patchControlPoints must be greater than zero and less than or equal to VkPhysicalDeviceLimits::maxTessellationPatchSize

Valid Usage (Implicit)

• commandBuffer must be a valid VkCommandBuffer handle
• commandBuffer must be in the recording state
• The VkCommandPool that commandBuffer was allocated from must support graphics operations
• This command must only be called outside of a video coding scope

Host Synchronization

• Host access to commandBuffer must be externally synchronized
• Host access to the VkCommandPool that commandBuffer was allocated from must be externally synchronized

Command Properties

Parameters

commandBuffer:VkCommandBuffer

the command buffer into which the command will be recorded.

patchControlPoints:int

specifies the number of control points per patch.

See CmdSetPrimitiveRestartEnable.

Parameters

commandBuffer:VkCommandBuffer

the command buffer into which the command will be recorded.

primitiveRestartEnable:boolean

controls whether a special vertex index value is treated as restarting the assembly of primitives. It behaves in the same way as VkPipelineInputAssemblyStateCreateInfo::primitiveRestartEnable

See CmdSetRasterizerDiscardEnable.

Parameters

commandBuffer:VkCommandBuffer

the command buffer into which the command will be recorded.

rasterizerDiscardEnable:boolean

controls whether primitives are discarded immediately before the rasterization stage.
