C Specification

To dynamically set the lineRasterizationMode state, call:

// Provided by VK_EXT_extended_dynamic_state3, VK_EXT_shader_object
void vkCmdSetLineRasterizationModeEXT(
    VkCommandBuffer                             commandBuffer,
    VkLineRasterizationModeEXT                  lineRasterizationMode);


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

  • lineRasterizationMode specifies the lineRasterizationMode state.


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

Valid Usage
  • VUID-vkCmdSetLineRasterizationModeEXT-None-08558
    Either the extendedDynamicState3LineRasterizationMode feature or the shaderObject feature or both must be enabled

  • VUID-vkCmdSetLineRasterizationModeEXT-lineRasterizationMode-07418
    If lineRasterizationMode is VK_LINE_RASTERIZATION_MODE_RECTANGULAR_EXT, then the rectangularLines feature must be enabled

  • VUID-vkCmdSetLineRasterizationModeEXT-lineRasterizationMode-07419
    If lineRasterizationMode is VK_LINE_RASTERIZATION_MODE_BRESENHAM_EXT, then the bresenhamLines feature must be enabled

  • VUID-vkCmdSetLineRasterizationModeEXT-lineRasterizationMode-07420
    If lineRasterizationMode is VK_LINE_RASTERIZATION_MODE_RECTANGULAR_SMOOTH_EXT, then the smoothLines feature must be enabled

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

  • VUID-vkCmdSetLineRasterizationModeEXT-lineRasterizationMode-parameter
    lineRasterizationMode must be a valid VkLineRasterizationModeEXT value

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

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

  • VUID-vkCmdSetLineRasterizationModeEXT-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
