A Learning Curve creating openGL_tests. As a beginner for modern OpenGL, this repository is created fullfilling the purpose of learning OpenGL and computer graphics. And also at the same time, engaging the practice of C++ language in play organise proper gl program with interfaces. This will be a process of documenting.
- First Gl window in the context of GLFW
- Initialise GLFW and GLEW
- Create the 'Big While Loop' for running program.
- Using
glClearColor()function to fill the gl-viewport with a certain colour.
- Drawing the First geo(Triangle/Polygon) -> Switch between
GL_TRIANGLESandGL_TRIANGLE_FAN - Setting up a few header files seperating these functions/classes:
- ObjectsCore -> An class stores geometry information, vertices are stored in
std::verctor<std::vector<float>>, and then using a few setters and getter functions to establish interface to bridge other contexts in this case the openGL; - GL_Create_Geometrys -> here stores a function taking the object and VAO VBO as reference, establish the data and send to buffer
- GL_ShaderFunctions -> here basically relates to functions create/compile shaders.
- ObjectsCore -> An class stores geometry information, vertices are stored in
Therefore using this structure, it will be possible to work further clearly rather than putting all the functions in one cpp file. I can seperate the shaders, shader compiling/validating, openGL geometry buffer and attribute inputs, geometry classes and methods, and context-main(glfw/win32).
