vkCmdSetCullMode

Set cull mode dynamically for a command buffer

To dynamically set the cull mode, call:

void vkCmdSetCullModeEXT(
    VkCommandBuffer commandBuffer,
    VkCullModeFlags cullMode);
  • commandBuffer is the command buffer into which the command will be recorded.
  • cullMode specifies the cull mode property to use for drawing.

This command sets the cull mode for subsequent drawing commands when drawing using shader objects, or when the graphics pipeline is created with VK_DYNAMIC_STATE_CULL_MODE set in VkPipelineDynamicStateCreateInfo::pDynamicStates. Otherwise, this state is specified by the VkPipelineRasterizationStateCreateInfo::cullMode value used to create the currently active pipeline.

Valid Usage

VUID-vkCmdSetCullMode-None-08971

At least one of the following must be true:

Valid Usage (Implicit)

VUID-vkCmdSetCullMode-commandBuffer-parameter

commandBuffer must be a valid VkCommandBuffer handle

VUID-vkCmdSetCullMode-cullMode-parameter

cullMode must be a valid combination of VkCullModeFlagBits values

VUID-vkCmdSetCullMode-commandBuffer-recording

commandBuffer must be in the recording state

VUID-vkCmdSetCullMode-commandBuffer-cmdpool

The VkCommandPool that commandBuffer was allocated from must support graphics operations

VUID-vkCmdSetCullMode-videocoding

This command must only be called outside of a video coding scope
