A framebuffer (frame buffer, or sometimes framestore) is a portion of RAM containing a bitmap that is driven to a video display from a memory buffer containing a complete frame of data.
The information in the memory buffer typically consists of color values for every pixel (point that can be displayed) on the screen. Color values are commonly stored in 1-bit binary (monochrome), 4-bit palettized, 8-bit palettized, 16-bit high color and 24-bit true color formats. An additional alpha channel is sometimes used to retain information about pixel transparency. The total amount of the memory required to drive the framebuffer depends on the resolution of the output signal, and on the color depth and palette size.
Framebuffers differ significantly from the vector displays that were common prior to the advent of faster graphics (and consequently the concept of a framebuffer). With a vector display, only the vertices of the graphics primitives are stored. The electron beam of the output display is then commanded to move from vertex to vertex, tracing an analog line across the area between these points. With a framebuffer, the electron beam (if the display technology uses one) is commanded to trace a left-to-right, top-to-bottom path across the entire screen, the way a television renders a broadcast signal. At the same time, the color information for each point on the screen is pulled from the framebuffer, creating a set of discrete picture elements (pixels).

Framebuffer
This video steps through the drawcalls for the rooftop map. Showcasing the strategic ordering of each element for an optimized frame. You can also see how wide the player detection circle could be; grass tiles choose a specific view prefab based on distance to character.
• 20 Opaque Drawcalls
• 8 Transparent Drawcalls
Responsibilities: The city background environment, and the playable area of the map; everything except for the playable map's border walls. All environment and character shader's Look & Feel, implementation and optimization

In this tutorial I'll show you how to create a custom framebuffer in OpenGL on which you can apply different post-processing effects.
