OpenGL® framebuffer simplifies buffer encoding for rendering, adding graphical effects and textures to images. It combines multiple buffers for efficient resource pooling. It allows for complex per-pixel effects and easy texture application, but requires an accompanying image and proper sizing and tying. It uses several other buffers simultaneously for efficiency.
The Open Graphics Library® (OpenGL®) framebuffer is an encoding object that simplifies buffer encoding for rendering. A primary use for the OpenGL® framebuffer is to add graphical effects to an image, which is usually a feature associated with graphic design programs. Another use of the OpenGL® framebuffer is to add texture to an image, such as static or blurry. While the effects and textures may look good on their own, the framebuffer is relatively useless unless there’s an image you can attach the effects or textures to; otherwise, nothing will be displayed. When the framebuffer is used, it combines several other buffers, which makes pooling of graphics resources more efficient than if the buffers were used separately.
Common graphic design programs have a list of special effects that can be added to an image, but doing the same thing in OpenGL® is quite complex. When the OpenGL® framebuffer is used, it places an image through many shaders that can create per-pixel effects. This means that complex effects can be applied to the OpenGL® image, making it easier to add effects and make those effects visually consistent.
There are many textures in the physical world: nearly every object has a visually distinct texture. If an OpenGL® project is supposed to emulate reality, it is important to be able to apply a texture. There are a few methods of adding a texture in this program, but the OpenGL® framebuffer is one of the simplest methods. Using this object, you can apply a texture to an area or graphic object using a small amount of code.
One problem with the OpenGL® framebuffer is that it can’t work on its own; there must be another image accompanying the effects or nothing will appear on the screen. Effects and textures are applied to an image, so this limitation rarely occurs. When a user creates a framebuffer object it is important that the framebuffer and image are the same size or there will be areas without effects or textures. The two must also be tied together or the image may not be correct in operation.
Another reason to use the OpenGL® framebuffer is that it uses several other buffers at the same time. This not only makes coordinating the buffers much easier, but fewer resources are required to run the framebuffer than using the other buffers separately. The buffers used are the color, index, depth, stencil and render buffers.
