The extension can be used to dynamically change sampling without need to swap pipelines. image:./image/image.png[] == Enabling the extension To be able to use this extension in Vulkan API: `VK_EXT_extended_dynamic_state3` depends on `VK_KHR_get_physical_device_properties2`, which is promoted to Vulkan 1.1. That is, to use this extension, `VK_EXT_extended_dynamic_state3` and either `VK_KHR_get_physical_device_properties2` or Vulkan 1.1 are required. Additionally this sample uses `VK_KHR_dynamic_rendering` which required Vulkan 1.2. == Using the extension To use the extension: 1) `VK_DYNAMIC_STATE_RASTERIZATION_SAMPLES_EXT` must be added to `VkPipelineDynamicStateCreateInfo`. 2) Method `void vkCmdSetRasterizationSamplesEXT(VkCommandBuffer commandBuffer, VkSampleCountFlagBits rasterizationSamples)` should be called with the active command buffer. == Resources https://registry.khronos.org/vulkan/specs/latest/man/html/VK_EXT_extended_dynamic_state3.html https://registry.khronos.org/vulkan/specs/latest/man/html/vkCmdSetRasterizationSamplesEXT.html
