Graphics programming is prevalent in many aspects of modern software development; and the need for graphics programmers is perhaps most felt with the explosion of game and graphics-oriented apps. OpenGL is at the center of this new wave of graphics-oriented programming as the chief rendering library for cross-platform development. Quality educational material is a necessity for newcomers to the field.OpenGL Essentials LiveLessons  introduces viewers to graphics programming through a moderately deep-dive into shader programming and the OpenGL API. Dr. Paul Varcholik guides viewers with a practical, hands-on approach to modern OpenGL application development. While these videos are geared towards programmers, no prior knowledge of graphics programming or 3D math is required. The lessons begin with “Hello, World!” style rendering (drawing a single point and triangle) and extend into introductory lighting models including ambient and diffuse lighting, specular highlights, point lights, and spot lights. The videos also cover texture mapping, environment mapping, normal mapping, and color blending and introduce viewers to 3D math in a straight-forward, stress-free fashion.Dr. Paul Varcholik is a twenty year veteran of the software development industry and has spent the past ten years writing video games. He was a lead software engineer at Electronic Arts working on titles including John Madden NFL Football and Superman Returns. He is currently a programming instructor at the Florida Interactive Entertainment Academy (FIEA) – a graduate degree program in game development at the University of Central Florida. Paul is also the author of Real-Time 3D Rendering with DirectX and HLSL: A Practical Guide to Graphics Programming.Skill LevelAll LevelsWhat You Will LearnOpenGL 4.4 API essentialsHow to write shaders using OpenGL Shading Language (GLSL)The 3D mathematics behind 3D graphicsHow to load and render 3D modelsMapping textures to 3D objectsAmbient and diffuse lighting, specular highlights, point lights, and spotlightsEnvironment mapping, fog, normal mapping, and color blendingSurvey additional topics in modern rendering, including post processing, shadow mapping, skeletal animation, geometry and tessellation shaders, deferred rendering, global illumination, and compute shaders.Who Should Take This CourseDevelopers looking for a practical introduction to 3D rendering and modern OpenGLCourse RequirementsFamiliarity with the C++ programming languageLesson 1: Introducing OpenGLThis lesson walks viewers through creating their first OpenGL application. It begins with a discussion of project setup, library dependencies, and a C++ rendering framework to support application development. In this lesson, viewers will write their first GLSL shaders and render simple geometry to the screen. The lesson concludes with a survey of the OpenGL graphics pipeline.Lesson 2: Understanding 3D MathThis lesson introduces viewers to the mathematics behind 3D graphics. The material is presented in a straight-forward, practical manner intended to reduce math anxiety. The lesson covers vectors, matrices, transformations, and the various coordinate systems encountered in 3D graphics.Lesson 3: Providing Shader InputLesson 3 extends the work from Lesson 1 and applies the mathematics learned in Lesson 2 through a number of hands-on demonstrations. In particular, viewers will learn about OpenGL buffers, providing input to GLSL shaders, and passing data between shader stages. Additionally, the lesson will cover loading and rendering 3D models.Lesson 4: Mapping Textures to 3D ObjectsLesson 4 covers loading textures and sampling them within GLSL shaders. The lesson also discusses texture wrapping modes useful, for example, for tiling a texture across large geometry. The lesson ends with a discussion of texture filtering modes used to improve the visual quality of textured objects.Lesson 5: Lighting 3D ObjectsLesson 5 introduces viewers to a number of lighting models including ambient and diffuse lighting, specular highlights, point lights, and spot lights. Throughout the lesson, viewers will extend their knowledge of GLSL and the OpenGL API.Lesson 6: Discovering Additional Rendering TechniquesIn this final lesson, viewers will implement more advanced rendering techniques, including environment mapping, fog, normal mapping, and color blending. The lesson concludes with a survey of post processing, shadow mapping, skeletal animation, geometry and tessellation shaders, deferred rendering, global illumination, and compute shaders.LiveLessons Video Training series publishes hundreds of hands-on, expert-led video tutorials covering a wide selection of technology topics designed to teach you the skills you need to succeed.
