VBO PBO FBO

Vertex buffer object(VBO)

allows vertex array data to be stored in high-performance graphics memory on the server side and
promotes efficient data transfer. If the buffer object is used to store pixel data, it is called Pixel Buffer Object(PBO).

 

Pixel Buffer Object borrows

all APIs from Vertex Buffer Object. The only difference is there are 2 additional tokens for PBOs: GL_PIXEL_PACK_BUFFER_ARB and GL_PIXEL_UNPACK_BUFFER_ARB.

 

FBO

itself does not have any image storage(buffer) in it. Instead, we must attach framebuffer-attachable images
(texture or renderbuffer objects) to the FBO.
