C Specification

To dynamically set whether an exclusive scissor is enabled or not, call:

// Provided by VK_NV_scissor_exclusive
void vkCmdSetExclusiveScissorEnableNV(
    VkCommandBuffer                             commandBuffer,
    uint32_t                                    firstExclusiveScissor,
    uint32_t                                    exclusiveScissorCount,
    const VkBool32*                             pExclusiveScissorEnables);


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

  • firstExclusiveScissor is the index of the first exclusive scissor rectangle whose state is updated by the command.

  • exclusiveScissorCount is the number of exclusive scissor rectangles updated by the command.

  • pExclusiveScissorEnables is a pointer to an array of VkBool32 values defining whether the exclusive scissor is enabled.


The exclusive scissor enables taken from element i of pExclusiveScissorEnables replace the current state for the scissor index firstExclusiveScissor + i, for i in [0, exclusiveScissorCount).

This command sets the exclusive scissor enable for subsequent drawing commands when drawing using shader objects, or when the graphics pipeline is created with VK_DYNAMIC_STATE_EXCLUSIVE_SCISSOR_ENABLE_NV set in VkPipelineDynamicStateCreateInfo::pDynamicStates. Otherwise, this state is implied by the VkPipelineViewportExclusiveScissorStateCreateInfoNV::exclusiveScissorCount value used to create the currently active pipeline, where all exclusiveScissorCount exclusive scissors are implicitly enabled and the remainder up to VkPhysicalDeviceLimits::maxViewports are implicitly disabled.

Valid Usage
  • VUID-vkCmdSetExclusiveScissorEnableNV-exclusiveScissor-07853
    The exclusiveScissor feature must be enabled, and the implementation must support at least specVersion 2 of the VK_NV_scissor_exclusive extension

Valid Usage (Implicit)
  • VUID-vkCmdSetExclusiveScissorEnableNV-commandBuffer-parameter
    commandBuffer must be a valid VkCommandBuffer handle

  • VUID-vkCmdSetExclusiveScissorEnableNV-pExclusiveScissorEnables-parameter
    pExclusiveScissorEnables must be a valid pointer to an array of exclusiveScissorCount VkBool32 values

  • VUID-vkCmdSetExclusiveScissorEnableNV-commandBuffer-recording
    commandBuffer must be in the recording state

  • VUID-vkCmdSetExclusiveScissorEnableNV-commandBuffer-cmdpool
    The VkCommandPool that commandBuffer was allocated from must support graphics operations

  • VUID-vkCmdSetExclusiveScissorEnableNV-videocoding
    This command must only be called outside of a video coding scope

  • VUID-vkCmdSetExclusiveScissorEnableNV-exclusiveScissorCount-arraylength
    exclusiveScissorCount must be greater than 0

Host Synchronization
  • Host access to commandBuffer must be externally synchronized

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