C Specification

To dynamically set the line width, call:

// Provided by VK_VERSION_1_0
void vkCmdSetLineWidth(
    VkCommandBuffer                             commandBuffer,
    float                                       lineWidth);


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

  • lineWidth is the width of rasterized line segments.


This command sets the line width for subsequent drawing commands when the graphics pipeline is created with VK_DYNAMIC_STATE_LINE_WIDTH set in VkPipelineDynamicStateCreateInfo::pDynamicStates. Otherwise, this state is specified by the VkPipelineRasterizationStateCreateInfo::lineWidth value used to create the currently active pipeline.

Valid Usage
  • VUID-vkCmdSetLineWidth-lineWidth-00788
    If the wideLines feature is not enabled, lineWidth must be 1.0

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

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

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

Host Synchronization
  • Host access to commandBuffer must be externally synchronized

  • Host access to the VkCommandPool that commandBuffer was allocated from must be externally synchronized
