C Specification

To begin conditional rendering, call:

// Provided by VK_EXT_conditional_rendering
void vkCmdBeginConditionalRenderingEXT(
    VkCommandBuffer                             commandBuffer,
    const VkConditionalRenderingBeginInfoEXT*   pConditionalRenderingBegin);


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

  • pConditionalRenderingBegin is a pointer to a VkConditionalRenderingBeginInfoEXT structure specifying parameters of conditional rendering.


Valid Usage
  • VUID-vkCmdBeginConditionalRenderingEXT-None-01980
    Conditional rendering must not already be active

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

  • VUID-vkCmdBeginConditionalRenderingEXT-pConditionalRenderingBegin-parameter
    pConditionalRenderingBegin must be a valid pointer to a valid VkConditionalRenderingBeginInfoEXT structure

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

  • VUID-vkCmdBeginConditionalRenderingEXT-commandBuffer-cmdpool
    The VkCommandPool that commandBuffer was allocated from must support graphics, or compute operations

  • VUID-vkCmdBeginConditionalRenderingEXT-videocoding
    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
