Pros of Vulkan-Samples

• Comprehensive collection of Vulkan samples covering various advanced topics
• Officially maintained by Khronos Group, ensuring up-to-date and accurate implementations
• Includes performance best practices and optimizations for different platforms

Cons of Vulkan-Samples

• May be overwhelming for beginners due to its extensive coverage of advanced topics
• Requires more setup and configuration compared to VulkanTutorial
• Less focused on step-by-step learning, more on demonstrating specific features

Code Comparison

VulkanTutorial:

VkApplicationInfo appInfo{};
appInfo.sType = VK_STRUCTURE_TYPE_APPLICATION_INFO;
appInfo.pApplicationName = "Hello Triangle";
appInfo.applicationVersion = VK_MAKE_VERSION(1, 0, 0);
appInfo.pEngineName = "No Engine";

Vulkan-Samples:

vkb::ApplicationInfo app_info;
app_info.app_name = "Vulkan Sample";
app_info.engine_name = "Vulkan Samples Framework";
app_info.api_version = VK_API_VERSION_1_0;

VulkanTutorial focuses on a more direct approach to Vulkan API usage, while Vulkan-Samples utilizes a framework to simplify some aspects of Vulkan development. The Vulkan-Samples code is more abstracted, potentially making it easier to use but less transparent for learning the raw API.

Pros of Vulkan

• More comprehensive and advanced examples covering a wider range of Vulkan features
• Includes performance optimizations and best practices for real-world applications
• Offers a larger collection of samples, providing a broader learning experience

Cons of Vulkan

• May be overwhelming for beginners due to its complexity and depth
• Less structured as a step-by-step tutorial, requiring more self-guided exploration
• Examples might be more challenging to understand without prior Vulkan knowledge

Code Comparison

VulkanTutorial (Basic triangle rendering):

void drawFrame() {
    vkWaitForFences(device, 1, &inFlightFence, VK_TRUE, UINT64_MAX);
    vkResetFences(device, 1, &inFlightFence);
    vkAcquireNextImageKHR(device, swapChain, UINT64_MAX, imageAvailableSemaphore, VK_NULL_HANDLE, &imageIndex);
    // ... (command buffer recording and submission)
}

Vulkan (Advanced rendering with multiple passes):

void buildCommandBuffers() {
    VkCommandBufferBeginInfo cmdBufInfo = vks::initializers::commandBufferBeginInfo();
    for (int32_t i = 0; i < drawCmdBuffers.size(); ++i) {
        vkBeginCommandBuffer(drawCmdBuffers[i], &cmdBufInfo);
        // ... (multiple render pass setup and drawing commands)
    }
}

Pros of awesome-vulkan

• Comprehensive collection of Vulkan resources, including tutorials, libraries, and tools
• Regularly updated with new Vulkan-related content
• Covers a wide range of topics and skill levels

Cons of awesome-vulkan

• Less structured learning path compared to VulkanTutorial
• May be overwhelming for beginners due to the sheer amount of information
• Lacks hands-on coding examples and step-by-step instructions

Code comparison

VulkanTutorial provides detailed code examples, while awesome-vulkan primarily links to external resources. Here's a sample from VulkanTutorial:

VkApplicationInfo appInfo{};
appInfo.sType = VK_STRUCTURE_TYPE_APPLICATION_INFO;
appInfo.pApplicationName = "Hello Triangle";
appInfo.applicationVersion = VK_MAKE_VERSION(1, 0, 0);
appInfo.pEngineName = "No Engine";

awesome-vulkan doesn't include direct code examples but links to various tutorials and projects that contain code samples.

Summary

VulkanTutorial offers a structured, step-by-step approach to learning Vulkan with detailed code examples. awesome-vulkan provides a comprehensive collection of Vulkan resources, covering a broader range of topics but with less direct guidance. VulkanTutorial is better suited for beginners looking for a hands-on learning experience, while awesome-vulkan is an excellent reference for developers at all levels seeking a wide variety of Vulkan-related information and tools.

Pros of vk_raytracing_tutorial_KHR

• Focuses specifically on ray tracing in Vulkan, providing in-depth coverage of this advanced topic
• Includes NVIDIA-specific optimizations and best practices for ray tracing
• Offers more recent and up-to-date content, reflecting the latest developments in Vulkan ray tracing

Cons of vk_raytracing_tutorial_KHR

• Less comprehensive for general Vulkan learning, as it's specialized for ray tracing
• May be more challenging for beginners due to its focus on advanced techniques
• Potentially less portable across different hardware vendors, given its NVIDIA-centric approach

Code Comparison

VulkanTutorial (basic triangle rendering):

vkCmdBeginRenderPass(commandBuffer, &renderPassInfo, VK_SUBPASS_CONTENTS_INLINE);
vkCmdBindPipeline(commandBuffer, VK_PIPELINE_BIND_POINT_GRAPHICS, graphicsPipeline);
vkCmdDraw(commandBuffer, 3, 1, 0, 0);
vkCmdEndRenderPass(commandBuffer);

vk_raytracing_tutorial_KHR (ray tracing pipeline setup):

VkRayTracingPipelineCreateInfoKHR rayPipelineInfo{VK_STRUCTURE_TYPE_RAY_TRACING_PIPELINE_CREATE_INFO_KHR};
rayPipelineInfo.stageCount = static_cast<uint32_t>(stages.size());
rayPipelineInfo.pStages = stages.data();
rayPipelineInfo.groupCount = static_cast<uint32_t>(groups.size());
rayPipelineInfo.pGroups = groups.data();
