What is OpenGL and why should you learn it?




OpenGL is a cross-platform API for rendering 2D and 3D graphics




OpenGL stands for Open Graphics Library. It is an application programming interface (API) that allows you to communicate with the graphics hardware of your computer. With OpenGL, you can create applications that render 2D and 3D graphics on various platforms, such as Windows, Linux, Mac OS X, Android, iOS, and WebGL. OpenGL is not a programming language itself, but rather a set of commands that you can use in your preferred language, such as C++, Java, Python, or Rust.


OpenGL is widely used in the industry for games, simulations, CAD, and more




OpenGL is one of the most popular APIs for graphics programming. It is used by many professional developers and hobbyists alike for creating games, simulations, computer-aided design (CAD), virtual reality (VR), augmented reality (AR), data visualization, and more. Some examples of famous applications that use OpenGL are Minecraft, Photoshop, Blender, Google Earth, and Unity.


OpenGL lets you access the power of modern GPUs and shaders




One of the main advantages of OpenGL is that it allows you to harness the power of modern graphics processing units (GPUs). GPUs are specialized hardware devices that can perform parallel computations very fast. They are especially good at handling graphics tasks, such as transforming vertices, rasterizing pixels, applying lighting effects, and more. With OpenGL, you can send commands to the GPU and let it do the heavy lifting for you.


Another key feature of OpenGL is that it supports shaders. Shaders are small programs that run on the GPU and determine how the graphics are rendered. Shaders give you a lot of flexibility and control over the appearance and behavior of your graphics. You can use shaders to create realistic materials, dynamic shadows, procedural textures, particle systems, and more.

Anton Gerdelan has written a book and online tutorials on OpenGL 4




Anton's OpenGL 4 Tutorials is a book that contains 40 chapters on various topics of OpenGL 4 and shaders. It is a practical guide that teaches you how to start 3D programming with OpenGL and shaders, using the most recent version of the API. It covers the basics, such as setting up the environment, creating windows, loading textures, drawing triangles, and using buffers. It also covers more advanced topics, such as lighting models, shadow mapping, normal mapping, skeletal animation, deferred rendering, and more.


The book is written in a clear and concise style, with plenty of illustrations, diagrams, and code examples. It also includes troubleshooting tips, tricks, and exercises to help you avoid common pitfalls and improve your skills. The book is suitable for anyone who wants to learn OpenGL and shaders, whether you are a beginner or an experienced programmer.


In addition to the book, Anton also provides online tutorials on his website. These tutorials are free to access and cover some of the same topics as the book, as well as some extra ones. Some of the online tutorials are:



  • Hello Triangle: Minimal code to draw a triangle using simple shaders and vertex buffers.



  • Extended Initialisation: Specifying OpenGL version, configuring the display, getting driver information, extension handling with GLEW, and adding a frames-per-second counter.



  • Shaders: Shaders determine the style of rendering.



  • Vertex Buffer Objects: Vertex buffer objects hold the mesh data to render on the graphics hardware.



  • Hot Reloading Shaders: Being able to edit your shader code and see what visually changes, live, without restarting your program.



  • Ray-Based Picking: Cast rays from mouse pointer to various primitive "bounding" shapes.



  • Cube Maps: Sky Boxes and Environment Mapping: Look at using GL cube maps for sky boxes, and environment-mapping reflection and refraction effects.



  • Morph Target Animation: Using interpolation between animation "targets". AKA "blend shapes".



  • WebGL Starter: Moving into WebGL.



  • It's More Fun to Compute: Introduction to compute shaders and ray traced rendering.



Anton Gerdelan's tutorials cover the basics and advanced topics of OpenGL 4




One of the strengths of Anton's OpenGL 4 Tutorials is that they cover both the basics and advanced topics of OpenGL 4. This means that you can learn everything you need to know about OpenGL 4 from one source. You don't have to switch between different books or websites that might have different styles or levels of difficulty.


The tutorials start with the fundamentals of OpenGL 4, such as how to create a window, how to draw simple shapes, how to use shaders, how to load textures, how to use buffers, etc. These topics are essential for any graphics programmer who wants to use OpenGL 4. They will give you a solid foundation for understanding how OpenGL 4 works and how to use it effectively.


The tutorials then move on to more advanced topics of OpenGL 4, such as how to implement different lighting models, how to create shadows, how to use normal maps, how to animate models, how to do deferred rendering, etc. These topics are more challenging but also more rewarding. They will allow you to create more realistic and impressive graphics with OpenGL 4. They will also expose you to some of the latest techniques and trends in graphics programming.


How can you get Anton's OpenGL 4 Tutorials ePub download?




You can buy the book on Itch.io or Amazon in ePub and MOBI formats




OpenGL 4 Tutorials ePub download, you can buy the book on Itch.io or Amazon. The book is available in ePub and MOBI formats, which are compatible with most devices and software.
