public Class XrSwapchainStateSamplerVulkanFB

Description

When XrSwapchainStateSamplerVulkanFB is specified in the call to UpdateSwapchainFB, texture sampler state for all images in the XrSwapchain will be updated for the compositor process. For most cases, the sampler state update is only required compositor-side, as that is where the swapchain images are sampled. If the application requires sampling of the swapchain images, the application will be responsible for updating the texture state using normal Vulkan mechanisms and synchronizing appropriately with application-side rendering.

When XrSwapchainStateSamplerVulkanFB is specified in the call to GetSwapchainStateFB, the sampler state will be populated with the current swapchain sampler state.

To use XrSwapchainStateSamplerVulkanFB, USE_GRAPHICS_API_VULKAN must be defined before including openxr_platform.h.

Valid Usage (Implicit)

• The XR_FB_swapchain_update_state_vulkan extension must be enabled prior to using XrSwapchainStateSamplerVulkanFB
• type must be TYPE_SWAPCHAIN_STATE_SAMPLER_VULKAN_FB
• next must be NULL or a valid pointer to the next structure in a structure chain
• minFilter must be a valid VkFilter value
• magFilter must be a valid VkFilter value
• mipmapMode must be a valid VkSamplerMipmapMode value
• wrapModeS must be a valid VkSamplerAddressMode value
• wrapModeT must be a valid VkSamplerAddressMode value
• swizzleRed must be a valid VkComponentSwizzle value
• swizzleGreen must be a valid VkComponentSwizzle value
