[英]Vulkan: Image error when recreating the swapchain after a window resize
So I'm trying to handle window resizing by recreating the swapchain and its image views and all that.所以我试图通过重新创建交换链及其图像视图以及所有这些来处理窗口大小调整。 This is the method that I'm using:
这是我正在使用的方法:
void VxRenderer::recreateSwapchain() {
device.waitIdle();
for (uint32_t i = 0; i < swapchainImageCount; ++i) {
vkDestroyFramebuffer(device, framebuffers[i], nullptr);
vkDestroyImageView(device, swapchainImageViews[i], nullptr);
}
vkResetCommandPool(device, commandPool, 0);
vkDestroyPipeline(device, pipeline, nullptr);
vkDestroySwapchainKHR(device, swapchain, nullptr);
createSwapchain();
getSwapchainImages();
createSwapchainImageViews();
createFramebuffers();
createGraphicsPipeline();
recordCommandBuffers();
}
The problem is that sometimes I get this error when resizing:问题是有时我在调整大小时会收到此错误:
Validation Error: [ VUID-VkPresentInfoKHR-pImageIndices-01296 ] Object 0: handle = 0x1d7260c6cc8,
type = VK_OBJECT_TYPE_QUEUE; | MessageID = 0xc7aabc16 | vkQueuePresentKHR(): pSwapchains[0] images
passed to present must be in layout VK_IMAGE_LAYOUT_PRESENT_SRC_KHR or VK_IMAGE_LAYOUT_SHARED_PRESENT_KHR
but is in VK_IMAGE_LAYOUT_UNDEFINED. The Vulkan spec states: Each element of pImageIndices must be the
index of a presentable image acquired from the swapchain specified by the corresponding element of the
pSwapchains array, and the presented image subresource must be in the VK_IMAGE_LAYOUT_PRESENT_SRC_KHR
layout at the time the operation is executed on a VkDevice
(https://github.com/KhronosGroup/Vulkan-Docs/search?q=)VUID-VkPresentInfoKHR-pImageIndices-01296)
It says that the problem comes from the elements in pImageIndices
in the VkPresentInfoKHR
structure, which I wrote as:它说问题来自
VkPresentInfoKHR
结构中pImageIndices
中的VkPresentInfoKHR
,我将其写为:
uint32_t imageIndex;
VkResult result =
vkAcquireNextImageKHR(device, swapchain, UINT64_MAX, imageAcquiredSemaphores[currentImage], VK_NULL_HANDLE, &imageIndex);
if (result == VK_ERROR_OUT_OF_DATE_KHR) {
recreateSwapchain();
return;
}
...
VkPresentInfoKHR presentInfo;
presentInfo.sType = VK_STRUCTURE_TYPE_PRESENT_INFO_KHR;
presentInfo.pNext = nullptr;
presentInfo.waitSemaphoreCount = 1;
presentInfo.pWaitSemaphores = &renderFinishedSemaphores[currentImage];
presentInfo.swapchainCount = 1;
presentInfo.pSwapchains = &swapchain;
presentInfo.pImageIndices = &imageIndex;
presentInfo.pResults = nullptr;
You need to transfer your image from the undefined layout in which it starts to a presentable image format, depending on what exactly you're doing with it.您需要将您的图像从未定义的布局转换为可呈现的图像格式,具体取决于您正在使用它做什么。 For example, if you're using it as a texture in a shader, it needs to be in
SHADER_READ_ONLY_OPTIMAL
layout.例如,如果您将其用作着色器中的纹理,则它需要位于
SHADER_READ_ONLY_OPTIMAL
布局中。
You can do this in multiple ways, one of them being an image memory barrier that you can submit to a transient queue.您可以通过多种方式做到这一点,其中之一是您可以提交到临时队列的图像内存屏障。 And you absolutely need to do this after recreating your swap chain, because your entire context is invalidated by the window resize operation.
并且您绝对需要在重新创建交换链后执行此操作,因为窗口大小调整操作会使整个上下文无效。
