OpenGL C++ Version
To create a simple OpenGL program in C++, follow these steps:
- Set up the OpenGL environment by including the necessary headers and linking with the OpenGL libraries.
- Initialize the GLFW library with
glfwInit()
and set the version and profile withglfwWindowHint()
. - Create a window with
glfwCreateWindow()
and make the context current withglfwMakeContextCurrent()
. - Initialize GLEW to access OpenGL functions with
glewInit()
. - Set the viewport with
glViewport()
to define the area of the window to render to. - Create a vertex buffer object (VBO) and vertex array object (VAO) to store the vertex data.
- Define the vertices of the object to be rendered and bind the VBO and VAO.
- Create vertex and fragment shaders using GLSL and compile them.
- Link the shaders into a shader program and use it by calling
glUseProgram()
. - Enter the main rendering loop and clear the color buffer with
glClear()
before drawing the object withglDrawArrays()
orglDrawElements()
. - Swap the front and back buffers with
glfwSwapBuffers()
and poll for events withglfwPollEvents()
.
These steps will create a basic OpenGL program in C++ for rendering simple objects.
