: Use a library like FreeType to rasterize glyphs into a grayscale texture. You map specific texture coordinates to rectangles (quads) to display each letter.
// Specify the vertex data GLfloat vertices[] = -0.5f, -0.5f, 0.0f, 0.5f, -0.5f, 0.0f, 0.0f, 0.5f, 0.0f ; opengl 2
Before OpenGL 2.0, developers were stuck with the . Think of this like a kitchen where you can only order from a set menu—you could toggle lighting on or off or choose from a few blending modes, but you couldn't "cook" your own visual effects. : Use a library like FreeType to rasterize
Shaders are small programs that run on the GPU. Think of this like a kitchen where you
Its streamlined cousin, OpenGL ES 2.0 , became the engine behind the mobile gaming revolution on early iPhones and Android devices.
// Make the window's context current glfwMakeContextCurrent(window);
OpenGL 2.0 introduced the . This allowed programmers to write small programs called shaders that ran directly on the GPU.
