Framebuffer

Framebuffers allow rendering into textures instead of directly to the screen. Typical uses: render-to-texture, post-processing, off-screen rendering, mini-maps, lighting effects.

Creating

Framebuffer framebuffer(1280, 720);

Binding

framebuffer.Bind();
// ... render into the framebuffer ...
framebuffer.Unbind(); // back to the default framebuffer

Resizing

framebuffer.Resize(1920, 1080);

Reading the result

GLuint texture = framebuffer.GetTextureID();

Like other GPU resources, Framebuffer is move-only.
