The playlist you linked — Vulkan Game Engine Tutorial — is a tutorial series (in C++) on using Vulkan (the graphics API) to build a rendering engine.

Use this as a roadmap while you watch, to understand what each stage is trying to teach (which should also help you as you already want to learn CMake etc.). #### - The series is not about drawing a few shapes — it walks you through building a minimal but real “game engine / rendering engine” in Vulkan.

YouTube[6]")] | | | | --- | --- | | | | | | | | | | | | | | | | | | | | | | Why this progression matters: Vulkan is very explicit and low-level. Unlike high-level APIs where windowing, pipeline, memory management are hidden, Vulkan makes you handle all of them. The early tutorials set up the skeleton; once that’s correct, drawing anything becomes straightforward. #### Given your interest in programming, learning advanced tools and building from first principles:[[edit](https://freemwiki.com/index.php?title=Openai/692b5dfe-c870-8001-8b1b-e406111f0f53&veaction=edit§ion=6 "Edit section: Given your interest in programming, learning advanced tools and building from first principles:") | [edit source](https://freemwiki.com/index.php?title=Openai/692b5dfe-c870-8001-8b1b-e406111f0f53&action=edit§ion=6 "Edit section's source code: Given your interest in programming, learning advanced tools and building from first principles:")] * This series aligns well: you’ll get to see how a “real-engine backbone” is built. * Since you also want to learn CMake, once you start coding along, you’ll likely need a build system — you’ll appreciate how project structure, dependencies (Vulkan SDK, libs) come together. * Because you enjoy technical depth (as with your physics and math interests for contour integrals, pulley problems, etc.), the explicitness of Vulkan will appeal: nothing magical is hidden, you must understand each layer. Also — many developers recommend reinforcing Vulkan learning with other resources: for example, some in a discussion write that after doing a Vulkan tutorial you should check out resources like LearnOpenGL or the official Khronos Group documentation to understand shader programming and graphics concepts more broadly.

People often recommend being comfortable with matrices, vectors, and shaders when venturing further.

Good practice to study each piece thoroughly, and build incrementally. #### Since you already plan to learn CMake and enjoy rigorous, detail-oriented learning:[[edit](https://freemwiki.com/index.php?title=Openai/692b5dfe-c870-8001-8b1b-e406111f0f53&veaction=edit§ion=8 "Edit section: Since you already plan to learn CMake and enjoy rigorous, detail-oriented learning:") | [edit source](https://freemwiki.com/index.php?title=Openai/692b5dfe-c870-8001-8b1b-e406111f0f53&action=edit§ion=8 "Edit section's source code: Since you already plan to learn CMake and enjoy rigorous, detail-oriented learning:")] 1. Watch tutorial 1–7 carefully, and implement them yourself (don’t just watch — code along). 2. Complement with resources like LearnOpenGL (for shader + graphics math) and the official docs / guides for Vulkan. 3. Once you complete tutorial 7 and “hello triangle + basic pipeline” — try to extend: draw more geometry, maybe try a simple 3D triangle or basic camera. This will reinforce what you learned. 4. Use CMake for project structure — it will help organize code, make it easier to build on, and align with future projects. If you like — I can pull up a detailed “cheat-sheet / notes summary” for tutorials 1–7 (with key Vulkan API calls, pipeline states, what each struct means, what to watch out for). Do you want me to build that for you now? ### User: no not like this generate notes for this and put them in a pdf or something so i can download it[[edit](https://freemwiki.com/index.php?title=Openai/692b5dfe-c870-8001-8b1b-e406111f0f53&veaction=edit§ion=9 "Edit section: User: no not like this generate notes for this and put them in a pdf or something so i can download it") | [edit source](https://freemwiki.com/index.php?title=Openai/692b5dfe-c870-8001-8b1b-e406111f0f53&action=edit§ion=9 "Edit section's source code: User: no not like this generate notes for this and put them in a pdf or something so i can download it")] no not like this generate notes for this and put them in a pdf or something so i can download it ### Assistant: Your PDF is ready![[edit](https://freemwiki.com/index.php?title=Openai/692b5dfe-c870-8001-8b1b-e406111f0f53&veaction=edit§ion=10 "Edit section: Assistant: Your PDF is ready!") | [edit source](https://freemwiki.com/index.php?title=Openai/692b5dfe-c870-8001-8b1b-e406111f0f53&action=edit§ion=10 "Edit section's source code: Assistant: Your PDF is ready!")] Your PDF is ready! 👉 Download here: vulkan_tutorial_notes.pdf[[9]](https://freemwiki.com/index.php?oldid=593853&title=Openai%2F692b5dfe-c870-8001-8b1b-e406111f0f53#cite_note-9) If you want: * a more detailed version * diagrams / flowcharts * separate PDFs per tutorial * handwritten-style notes Just tell me — I can generate them. ### User: where are the explanations of the concepts?[[edit](https://freemwiki.com/index.php?title=Openai/692b5dfe-c870-8001-8b1b-e406111f0f53&veaction=edit§ion=11 "Edit section: User: where are the explanations of the concepts?") | [edit source](https://freemwiki.com/index.php?title=Openai/692b5dfe-c870-8001-8b1b-e406111f0f53&action=edit§ion=11 "Edit section's source code: User: where are the explanations of the concepts?")] where are the explanations of the concepts? ### Assistant: Here you go — a much more detailed explanation of all concepts from Tutorials 1–7.[[edit](https://freemwiki.com/index.php?title=Openai/692b5dfe-c870-8001-8b1b-e406111f0f53&veaction=edit§ion=12 "Edit section: Assistant: Here you go — a much more detailed explanation of all concepts from Tutorials 1–7.") | [edit source](https://freemwiki.com/index.php?title=Openai/692b5dfe-c870-8001-8b1b-e406111f0f53&action=edit§ion=12 "Edit section's source code: Assistant: Here you go — a much more detailed explanation of all concepts from Tutorials 1–7.")] Here you go — a much more detailed explanation of all concepts from Tutorials 1–7. 📄 Download the full detailed notes PDF: 👉 vulkan_concepts_detailed.pdf[[10]](https://freemwiki.com/index.php?oldid=593853&title=Openai%2F692b5dfe-c870-8001-8b1b-e406111f0f53#cite_note-10) If you want: * diagrams (pipeline, swapchain, render pass flow) * memory layout charts * separate PDFs per tutorial * handwritten-style notes * longer explanations for any section Just tell me — I can generate them. ### User: 1 and where bugs usually hide, code snippets[[edit](https://freemwiki.com/index.php?title=Openai/692b5dfe-c870-8001-8b1b-e406111f0f53&veaction=edit§ion=13 "Edit section: User: 1 and where bugs usually hide, code snippets") | [edit source](https://freemwiki.com/index.php?title=Openai/692b5dfe-c870-8001-8b1b-e406111f0f53&action=edit§ion=13 "Edit section's source code: User: 1 and where bugs usually hide, code snippets")] 1 and where bugs usually hide, code snippets ### Assistant: Great — beginner-friendly, but with real explanations, code snippets, and “here’s where bugs hide” warnings.[[edit](https://freemwiki.com/index.php?title=Openai/692b5dfe-c870-8001-8b1b-e406111f0f53&veaction=edit§ion=14 "Edit section: Assistant: Great — beginner-friendly, but with real explanations, code snippets, and “here’s where bugs hide” warnings.") | [edit source](https://freemwiki.com/index.php?title=Openai/692b5dfe-c870-8001-8b1b-e406111f0f53&action=edit§ion=14 "Edit section's source code: Assistant: Great — beginner-friendly, but with real explanations, code snippets, and “here’s where bugs hide” warnings.")] Great — beginner-friendly, but with real explanations, code snippets, and “here’s where bugs hide” warnings.

In Linux, windows come from systems like X11 or Wayland. In macOS, they come from Cocoa (Objective-C). The BIG problem: ##### So Vulkan cannot assume one method.[[edit](https://freemwiki.com/index.php?title=Openai/692b5dfe-c870-8001-8b1b-e406111f0f53&veaction=edit§ion=20 "Edit section: So Vulkan cannot assume one method.") | [edit source](https://freemwiki.com/index.php?title=Openai/692b5dfe-c870-8001-8b1b-e406111f0f53&action=edit§ion=20 "Edit section's source code: So Vulkan cannot assume one method.")] That’s why we use GLFW (or SDL). GLFW hides OS differences and gives you a simple API: glfwInit(); glfwWindowHint(GLFW_CLIENT_API, GLFW_NO_API); // important for Vulkan GLFWwindow* window = glfwCreateWindow(800, 600, "My Window", nullptr, nullptr); ##### If you forget:[[edit](https://freemwiki.com/index.php?title=Openai/692b5dfe-c870-8001-8b1b-e406111f0f53&veaction=edit§ion=21 "Edit section: If you forget:") | [edit source](https://freemwiki.com/index.php?title=Openai/692b5dfe-c870-8001-8b1b-e406111f0f53&action=edit§ion=21 "Edit section's source code: If you forget:")] glfwWindowHint(GLFW_CLIENT_API, GLFW_NO_API); GLFW will try to create an OpenGL context.

What’s your background and how deep do you want each explanation to be (pick one)? 1. Beginner C++ / new to graphics — plain English, analogies, little math, step-by-step how things fit together. 2. Intermediate (comfortable with C++ & some GL/OpenGL) — deeper API details, code snippets, and where bugs usually hide. 3. Advanced / engine dev — exact Vulkan structs, memory/synchronization pitfalls, SPIR-V/shader details, and optimization notes. Reply with 1, 2, or 3 (or a short combo like “2, focus on shaders”), and I’ll start teaching every subtopic from Tutorials 1–7 in teacher style — one concept at a time, with questions and short checks so you actually understand. ## References[[edit](https://freemwiki.com/index.php?title=Openai/692b5dfe-c870-8001-8b1b-e406111f0f53&veaction=edit§ion=47 "Edit section: References") | [edit source](https://freemwiki.com/index.php?title=Openai/692b5dfe-c870-8001-8b1b-e406111f0f53&action=edit§ion=47 "Edit section's source code: References")] 1.
