C Specification

To dynamically set the polygon mode, call:

// Provided by VK_EXT_extended_dynamic_state3, VK_EXT_shader_object
void vkCmdSetPolygonModeEXT(
    VkCommandBuffer                             commandBuffer,
    VkPolygonMode                               polygonMode);


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

  • polygonMode specifies polygon mode.


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

Valid Usage
  • VUID-vkCmdSetPolygonModeEXT-None-09423
    At least one of the following must be true:

  • VUID-vkCmdSetPolygonModeEXT-fillModeNonSolid-07424
    If the fillModeNonSolid feature is not enabled, polygonMode must be VK_POLYGON_MODE_FILL or VK_POLYGON_MODE_FILL_RECTANGLE_NV

  • VUID-vkCmdSetPolygonModeEXT-polygonMode-07425
    If the VK_NV_fill_rectangle extension is not enabled, polygonMode must not be VK_POLYGON_MODE_FILL_RECTANGLE_NV

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

  • VUID-vkCmdSetPolygonModeEXT-polygonMode-parameter
    polygonMode must be a valid VkPolygonMode value

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

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

  • VUID-vkCmdSetPolygonModeEXT-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
