vkCmdSetLineRasterizationModeEXT(3)

C Specification

To dynamically set the lineRasterizationMode state, call:

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

Parameters

commandBuffer is the command buffer into which the command will be recorded.
lineRasterizationMode specifies the lineRasterizationMode state.

Description

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 VkPipelineRasterizationLineStateCreateInfoKHR::lineRasterizationMode value used to create the currently active pipeline.

Valid Usage
