Introduction➹
The following discusses different topics in Modern OpenGL Tutorials.OpenGL is a graphics library that can be used to render interactive 2D and 3D graphics applications.OpenGL has wide range of applications.This tutorials attempts to teach basic to advanced concepts one at a time. The goal is to create an advanced , multifunctional library from scratch. The tutorials will be a set of C++ header (.h) files.This tutorial is primarily targeted for windows OS. Visual Studio development environment is used for writing, compiling and debugging the code.
VedaOpenGLLib Implementation - Initializing OpenGL Context➹
OpenGL is a drawing library that requires a context to draw upon.
Creating OpenGL context in windows OS is not a trivial task. It's mainly because opengl32.lib supplied by windows OS supports OpenGL specification 1.1.
The display card providers such as NVidia or Intel or AMD actually implement the latest and greatest OpenGL specification, including additional functionality and supply it as OpenGL Installable Client Driver or ICD.
Lesson01 : Initializing OpenGL Context➹
This lesson discusses implementing the basic operations of creating a hosting window, Initializing it with OpenGL context, rendering it and handle mouse/keyboard inputs.
A scene consists of a set of 3D objects. Transformations such as translation, scaling and rotation as a result of Camera movement, mouse and keyboard input brings them into life.
For example the following diagram shows a multi color cube with 50 degrees pitch and 20 degrees yaw.
