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

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 PipelineDynamicStateCreateInfo::pDynamicStates. Otherwise, this state is specified by the PipelineTessellationStateCreateInfo::patchControlPoints value used to create the currently active pipeline.

Valid Usage

• At least one of the following must be true:

  • The extendedDynamicState2PatchControlPoints feature is enabled

  • The shaderObject feature is enabled

• patchControlPoints must be greater than zero and less than or equal to PhysicalDeviceLimits::maxTessellationPatchSize

Valid Usage (Implicit)

• commandBuffer must be a valid CommandBuffer handle

• commandBuffer must be in the recording state

• The CommandPool that commandBuffer was allocated from must support QUEUE_GRAPHICS_BIT 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 CommandPool that commandBuffer was allocated from must be externally synchronized

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

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 PipelineDynamicStateCreateInfo::pDynamicStates. Otherwise, this state is specified by the PipelineColorBlendStateCreateInfo::logicOp value used to create the currently active pipeline.

Valid Usage

• At least one of the following must be true:

  • The extendedDynamicState2LogicOp feature is enabled

  • The shaderObject feature is enabled

Valid Usage (Implicit)

• commandBuffer must be a valid CommandBuffer handle

• logicOp must be a valid LogicOp value

• commandBuffer must be in the recording state

• The CommandPool that commandBuffer was allocated from must support QUEUE_GRAPHICS_BIT 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 CommandPool that commandBuffer was allocated from must be externally synchronized

VkPhysicalDeviceExtendedDynamicState2FeaturesEXT - Structure describing what extended dynamic state can be used

Members

This structure describes the following features:

Description

If the PhysicalDeviceExtendedDynamicState2FeaturesEXT structure is included in the pNext chain of the PhysicalDeviceFeatures2 structure passed to getPhysicalDeviceFeatures2, it is filled in to indicate whether each corresponding feature is supported. If the application wishes to use a Device with any features described by PhysicalDeviceExtendedDynamicState2FeaturesEXT, it must add an instance of the structure, with the desired feature members set to TRUE, to the pNext chain of DeviceCreateInfo when creating the Device.
