vkCmdSetFrontFace
To dynamically set the front face orientation, call:
void vkCmdSetFrontFace(
VkCommandBuffer commandBuffer,
VkFrontFace frontFace);
pub fn cmd_set_front_face(
command_buffer: vk::CommandBuffer,
front_face: vk::FrontFace,
);
void vkCmdSetFrontFaceEXT(
VkCommandBuffer commandBuffer,
VkFrontFace frontFace);
pub fn cmd_set_front_face_ext(
command_buffer: vk::CommandBuffer,
front_face: vk::FrontFace,
);
commandBufferis the command buffer into which the command will be recorded.frontFaceis a VkFrontFace value specifying the front-facing triangle orientation to be used for culling.
This command sets the front face orientation for subsequent drawing commands
when drawing using shader objects, or
when the graphics pipeline is created with VK_DYNAMIC_STATE_FRONT_FACE
set in VkPipelineDynamicStateCreateInfo::pDynamicStates.
Otherwise, this state is specified by the
VkPipelineRasterizationStateCreateInfo::frontFace value used to
create the currently active pipeline.
Valid Usage
VUID-vkCmdSetFrontFace-None-08971
At least one of the following must be true:
- the
extendedDynamicStatefeature is enabled - the
shaderObjectfeature is enabled - the value of VkApplicationInfo::
apiVersionused to create the VkInstance parent ofcommandBufferis greater than or equal to Version 1.3
Valid Usage (Implicit)
VUID-vkCmdSetFrontFace-commandBuffer-parameter
commandBuffer must be a valid VkCommandBuffer handle
VUID-vkCmdSetFrontFace-frontFace-parameter
frontFace must be a valid VkFrontFace value
VUID-vkCmdSetFrontFace-commandBuffer-recording
commandBuffer must be in the recording state
VUID-vkCmdSetFrontFace-commandBuffer-cmdpool
The VkCommandPool that commandBuffer was allocated from must support VK_QUEUE_GRAPHICS_BIT operations
VUID-vkCmdSetFrontFace-videocoding
This command must only be called outside of a video coding scope
