Using Vulkan, I americium reference from an image to a vector of unsigned char. It useful great.
vkCmdTraceRaysKHR( screenshotCmdBuffer, &shaderBindingTables.raygen.stridedDeviceAddressRegion, &shaderBindingTables.miss.stridedDeviceAddressRegion, &shaderBindingTables.hit.stridedDeviceAddressRegion, &emptySbtEntry, size_x, size_y, 1); vks::tools::setImageLayout( screenshotCmdBuffer, screenshotStorageImage.image, VK_IMAGE_LAYOUT_GENERAL, VK_IMAGE_LAYOUT_TRANSFER_SRC_OPTIMAL, subresourceRange); VkBufferImageCopy copyRegion{}; copyRegion.bufferOffset = 0; copyRegion.bufferRowLength = 0; copyRegion.bufferImageHeight = 0; copyRegion.imageSubresource.aspectMask = VK_IMAGE_ASPECT_COLOR_BIT; copyRegion.imageSubresource.mipLevel = 0; copyRegion.imageSubresource.baseArrayLayer = 0; copyRegion.imageSubresource.layerCount = 1; copyRegion.imageOffset = { 0, 0, 0 }; copyRegion.imageExtent.width = size_x; copyRegion.imageExtent.height = size_y; copyRegion.imageExtent.depth = 1; vkCmdCopyImageToBuffer(screenshotCmdBuffer, screenshotStorageImage.image, VK_IMAGE_LAYOUT_TRANSFER_SRC_OPTIMAL, screenshotStagingBuffer.buffer, 1, ©Region); VkBufferMemoryBarrier obstruction = {}; barrier.sType = VK_STRUCTURE_TYPE_BUFFER_MEMORY_BARRIER; barrier.srcAccessMask = VK_ACCESS_TRANSFER_WRITE_BIT; barrier.dstAccessMask = VK_ACCESS_HOST_READ_BIT; barrier.buffer = screenshotStagingBuffer.buffer; barrier.size = screenshotStagingBuffer.size; vkCmdPipelineBarrier( screenshotCmdBuffer, VK_PIPELINE_STAGE_TRANSFER_BIT, VK_PIPELINE_STAGE_HOST_BIT, 0, 0, nullptr, 1, &barrier, 0, nullptr ); vulkanDevice->flushCommandBuffer(screenshotCmdBuffer, queue); memcpy(&fbpixels[0], screenshotStagingBuffer.mapped, size);How would I spell astir penning from a vector of unsigned char to an image?
This is simply a codification that I've been trying, but it does not work:
memcpy(screenshotStagingBuffer.mapped, &uc_output_data[0], size); VkImageSubresourceRange subresourceRange = { VK_IMAGE_ASPECT_COLOR_BIT, 0, 1, 0, 1 }; vks::tools::setImageLayout( screenshotCmdBuffer, screenshotStorageImage.image, VK_IMAGE_LAYOUT_GENERAL, VK_IMAGE_LAYOUT_TRANSFER_DST_OPTIMAL, subresourceRange); VkBufferImageCopy copyRegion{}; copyRegion.bufferOffset = 0; copyRegion.bufferRowLength = 0; copyRegion.bufferImageHeight = 0; copyRegion.imageSubresource.aspectMask = VK_IMAGE_ASPECT_COLOR_BIT; copyRegion.imageSubresource.mipLevel = 0; copyRegion.imageSubresource.baseArrayLayer = 0; copyRegion.imageSubresource.layerCount = 1; copyRegion.imageOffset = { 0, 0, 0 }; copyRegion.imageExtent.width = size_x; copyRegion.imageExtent.height = size_y; copyRegion.imageExtent.depth = 1; vkCmdCopyBufferToImage( screenshotCmdBuffer, screenshotStagingBuffer.buffer, screenshotStorageImage.image, VK_IMAGE_LAYOUT_TRANSFER_DST_OPTIMAL, 1, ©Region); VkBufferMemoryBarrier obstruction = {}; barrier.sType = VK_STRUCTURE_TYPE_BUFFER_MEMORY_BARRIER; barrier.srcAccessMask = VK_ACCESS_HOST_READ_BIT; barrier.dstAccessMask = VK_ACCESS_TRANSFER_WRITE_BIT; barrier.buffer = screenshotStagingBuffer.buffer; barrier.size = screenshotStagingBuffer.size; vkCmdPipelineBarrier( screenshotCmdBuffer, VK_PIPELINE_STAGE_HOST_BIT, VK_PIPELINE_STAGE_TRANSFER_BIT, 0, 0, nullptr, 1, &barrier, 0, nullptr); vulkanDevice->flushCommandBuffer(screenshotCmdBuffer, queue);Should I beryllium utilizing an image representation obstruction alternatively of a buffer representation barrier?
The validation layers says that:
